web2py response stream

For each application installed you can use the site page to: All the functionality available from the web2py admin site page is also accessible programmatically via the API defined in the module gluon/admin.py. After you login into admin you can edit the admin configuration file via the URL: Notice that admin can be used to edit itself. If you cut and paste @////15/beach.jpg into wiki pages you embed the image. The session is a container for variables that are stored server-side. If you click on test, web2py will run tests. Now you have a copy of the welcome application. We also require that the "image_id" be represented by the "title", '%(title)s', of the corresponding record. Clicking on "administrative interface" takes you to the login page for the administration interface. You can extend oembed support by registering more services. Any wiki page can be retrieved and embedded at any point in your code. The scaffolding app, sets default values of these parameters in the file "models/menu.py": In this section, we build a simple wiki from scratch using only low level APIs (as opposed to using the built-in wiki capabilities of web2py demonstrated in the next section). After the administrator logs into web2py, the browser is redirected to the "site" page. For security reasons, the developer is asked to choose a new password every time web2py starts unless the option is specified. There are two default controllers: "appadmin.py" and "default.py". In fact, the "static/css/web2py.css" stylesheet is well documented and described in Chapter 5. The layout view keeps the look and feel of the two pages consistent. For example _href is the href attribute, _class is the class attribute, etc. This data is presented to the administrator as charts under the application "about" page. The blockage for me is that the documentation is somewhat disconnected in that none of the examples are in the context of web2py environment e.g.whether and how to use pdf.output vs response.stream . You can change color, columns, size, borders and background without editing the HTML. As far as the database is concerned, we had already declared this when we defined the table "post". > from what I understand, Tornado is a multithreaded event-loop, whith a buil-in http-server, as a replacement for, say, apache. Web2Py how to download multiple files with response.stream I have multiple json and csv files under the static folder of Web2Py that I'd like to download from the server to local client with a web2py controller and response.stream. The 'target' tag is a DIV defined in line 52. Lines 3-6 define a table "image". You can use the env parameter of auth.wiki to expose functions to your wiki. Of course, before upgrading be sure to have a full working backup! As before, from the site page in admin, create a new application called images, and navigate to the edit page: We start by creating a model, a representation of the persistent data in the application (the images to upload, their names, and the comments). Pack compiled. Lost password; Create your account; matplotlib howto. We will call this application "myapp". Go. web2py automatically and transparently tracks visitors using sessions and cookies. The unique id is sent to the browser via a cookie. web2py Spanish; web2py English; web2py Spanish (Translation in progress) if the table does not exist, the table is created; if the table exists and does not correspond to the definition, the table is altered accordingly, and if a field has a different type, web2py tries to convert its contents; if the table exists and corresponds to the definition, web2py does nothing. The web2py API for Role-Based Access Control is quite sophisticated, but for now we will limit ourselves to restricting access to the show action to authenticated users, deferring a more detailed discussion to Chapter 9. Here is an example of usage. The "show" action, though, should have a view, so return to admin and create a new view called "default/show.html". Note that you still have to call auth.wiki() in the controller or view in order to expose the wiki interface, since the resolve=False parameter instructs the auth object to just build the wiki model without any other interface setup. Free and open source full-stack enterprise framework for agile development of secure database-driven web-based applications, written and programmable in Python. - web2py/web2py Blocks of code start with lines ending in colon (:) and end in lines beginning with the keyword pass. Write the corresponding actions in the default controller: Then create a view "default/first.html" for the first action, and enter: Finally, create a view "default/second.html" for the second action: In both views we have extended the basic "layout.html" view that comes with web2py. Connect! Click on the index link to visit the newly created page. The web2py program accepts various command line options which are discussed later. It determines how a record should be represented as a string. Validators are executed in the order they appear. Notice that everywhere admin shows syntax-highlighted code (for example, in error reports, web2py keywords are shown in orange). The administrative interface provides an aggregate views (type of traceback and number of occurrence) and a detailed view (all tickets are listed by ticket id). The > symbols separates the menu item title from the menu item link. IS_NOT_IN_DB(a, b) is a special validator that checks that the value of a field b for a new record is not already in a. Now create two pages (first and second), where the first page creates a form, asks the visitor's name, and redirects to the second page, which greets the visitor by name. If you want them to be readily available, use auth.wiki(resolve=False), and make sure table migrations are turned on: more on that on the Extending-the-auth-wiki-feature section following. Lines 13, 20 define and process create forms for a new page and a new comment and. The user function also exposes, among others, the following actions: Now, a first-time user needs to register in order to be able to log in and read or post comments. Proceed to create a view for the index action. We used double dash for nested menu items. and then per application, you must clone or otherwise configure a git repository. To use the session, modify the default controller: Notice that counter is not a web2py keyword but session is. Alternatively, you can choose to accept raw HTML instead of markmin syntax. Similarly you can use the wiki menu to upload a media file (for example an image) linked to the page. From now on, we will refer to this interface simply as appadmin. • response.body: a stringio object into which web2py writes the output page body. Parameters: stream – filename or read()able content; chunk_size (int) – Buffer size; request – the request object; attachment (bool) – prepares the correct headers to download the file as an attachment. It also provides a "controller/default.py" which exposes actions "index", "download", "user" for user management, and "call" for services. response.stream(file, chunk_size): quando un controller ritorna questo valore web2py invia il contenuto al client in blocchi delle dimensioni di chunk_size. This approach is better also because the name of the visitor stays in the session, and can be accessed by all actions and views in the application without having to be passed around explicitly. The administrative interface provides additional functionality that we briefly review here. If you click on a web2py keyword, you are redirected to a documentation page about the keyword. The visitor will be able to create pages, search them (by title), and edit them. appadmin replaces response.menu with its own menu, which provides links to the application's edit page in admin, the db (database administration) page, the state page, and the cache page. [qdb]. Upon successful upload, web2py displays the MD5 checksum of the uploaded file. The admin interface also provides a page where you can translate each string in the languages you desire to support. The value of the hypertext reference (href attribute) is: i.e., the URL within the same application and controller as the current request that calls the function called "show", passing a single argument to the function, args=image.id. To delete a record, click the corresponding checkbox to confirm that you are sure. In this case you will also be enabled to use the admin interface to push changes back into the repository, but this is an experimental feature. You can use an action with a different name. It is safer to store the data in a session. Folder names under static files are also collapsible. In web2py migrations are automatic, but can be disabled for each table by passing migrate=False as the last argument of define_table. Edit the "index" function as follows: Here is what the online editor looks like: Save it and go back to the edit page. The cast=int argument is optional but very important. web2py knows how to upload files (via streaming if they are large), rename them safely, and store them. This is done using the. Notice that the link is not present until the tables have been created. Both the auth object and the user function are already defined in the scaffolding application. Line 11 selects all comments that reference the current image, the, show: show a wiki page and its comments, and add new comments, documents: manage the documents attached to a page, download: download a document (as in the images example), search: display a search box and, via an Ajax callback, return all matching titles as the visitor types. Every time the visitor releases a key, the JavaScript code inside the onkeyup attribute is executed, client-side. Mind that this mechanism still assumes all users are trusted. To limit access to authenticated users, we need to complete three steps. return response. In web2py, you cannot simply return a file object but must instead use response.stream: import cStringIO file = cStringIO.StringIO(row.Picture) return response.stream(file) You might also consider using the web2py DAL and taking advantage of its built-in functionality for … The onkeyup attribute of the INPUT tag "keyword" is set. By clicking on this link you will be able to edit the web2py crontab file. It will allow you to deploy to GAE from the admin interface. Under the hood, Mercurial stores information about changes you make in your code into a hidden folder ".hg" in your app subfolder. If the application was installed form a packed compiled file, then this is not safe, because there is no source code to revert to, and the application will no longer work. For example, here is one possible way to rewrite the first action: where we are saying that the FORM tag contains two INPUT tags. Every URL gets mapped into a call to one of the functions in the controllers (actions). You can add language files, scan the app to discover all strings, and edit string translations via the web interface. the string representation in forms and tables. web2py always streams static files in chunks of 1MB, and sends PARTIAL CONTENT when the client sends a RANGE request for a subset of the file. With the first commit, a local Mercurial repository for the specific application will be created. The other arguments are the fields belonging to that table. The other steps are pretty much self-explanatory. In this way if a visitor has the language preference of the browser set to "Italian", web2py will use the Italian translation for the strings, if available. The "show" action selects the image with the id parsed from the request args and all comments related to the image. Also under the controllers tab in edit there is a "crontab" link. It is designed to help you by providing an easy access to the database. Let's now add a counter to this page that will count how many times the same visitor displays the page. As always, thanks for web2py and the great support, HC We will also add a counter that counts how many times the same user visits the page. There is also a source code version that runs on Windows, Mac, Linux, and other Unix systems. The system also keeps track of when students login and how many lines of code they add/remove to/from their code. It returns the HTML that gets embedded in the search page while the visitor types. IDEs usually have their own inter-process debugger, e.g. To install applications on Heroku or other hosting system you should look into the "scripts" folder for the appropriate script. If the URL points to a YouTube page, a Vimeo page, or a Flickr page, web2py contacts the corresponding web service and queries it about the proper way to embed the content. If you click on any file name, you can see the contents of the file with syntax highlighting. It takes three parameters: the URL of the action that performs the synchronous callback, a list of the IDs of variables to be sent to the callback (["keyword"]), and the ID where the response has to be inserted ("target"). find_by is not an action (because it takes an argument). You can query the IP address of your network interface by opening a command line and typing ipconfig on Windows or ifconfig on OS X and Linux. Also, by setting resolve to False in the method call, the wiki tables will be now accessible through the app's default db interface at /appadmin for managing wiki records. response.subtitle: parametro opzionale che può essere aggiunto alla vista. Be careful using the web based shell - because different shell requests will be executed in different threads. The meaning of the validators in lines 17-18 should be obvious. The image below shows the output of the test page for the welcome application. The code embedded in {{...}} is pure Python code with one caveat: indentation is irrelevant. If the form does not pass validation, error messages are inserted into the form and shown to the user, as below: In the next section we will show how forms can be generated automatically from a model. The Wizard works well for what it does but it is considered an experimental feature for two reasons: In any case the wizard is a handy tool for fast prototyping and it can be used to bootstrap a new application with an alternate layout and optional plugins. This process is designed to prevent directory traversal attacks. All the apps created under admin run under the same credentials on the same filesystem. review scripts/* and document them Allow streaming of large CSV files (keep connections after action returns the iterator). response.subtitle: parametro opzionale che può essere aggiunto alla vista. to make it works, files should be loaded using web2py interface (SQLFORM or programmatically - see the book). You can find more information about the MARKMIN syntax in chapter 5. auth.wiki is more powerful than the barebones MARKMIN helpers, supporting oembed and components. create, update and delete images and their comments: You can configure the default layout by editing "views/layout.html" but you can also configure it without editing the HTML. If the URL has an image extension, the link is embedded as an image, If the URL has an audio extension, the link is embedded as HTML5 audio, If the URL has a video extension, the link is embedded as HTML5 video. When developing, if there is no view, the action is rendered by the "generic.html" view that is provided with every web2py application. We assume the code below will replace any existing code in "db.py". Line 7 sets the value for the reference field, which is not part of the input form because of the, Line 8 creates an insert form SQLFORM for the, Line 9 processes the submitted form (the submitted form variables are in. Here [extension] is the requested extension. the index action in the default controller of the myapp application is called. All input should be validated and, in the above example, the burden of validation would fall on the second action. They may complain if you include the gluon library. Line 6 defines a format string for the table. All communications between the client and admin must always be local or encrypted; otherwise an attacker would be able to perform a man-in-the middle attack or a replay attack and execute arbitrary code on the server. It should look like this: Now, edit the "index" function as follows: Also from the edit page, edit the view "default/index.html" (the view file associated with the action) and completely replace the existing contents of that file with the following: Now the action returns a dictionary defining a message. Simply open a python shell and import this module. Try it here: makejson. If you were to edit the model and access appadmin again, web2py would generate SQL to alter the existing tables. The edit page tells you what is inside the application. web2py helps in two ways: 1) it allows you to create tests for every function that can be run in the browser from the edit page; and 2) when an error manifests itself, a ticket is issued to the visitor and the error is logged. The admin app also includes git integration. For activities like these (i.e. If not, make sure that in db.py migrations are enabled else the new required wiki tables will not be automatically created. Here is an example of how to access the XML-RPC handler from an external Python program. By default generic views are only allowed from localhost for development purposes. they have clearer code and are faster. web2py comes with three applications: Ready-to-use web2py applications are referred to as web2py appliances. response.download() has its arguments as request, db and is used for downloading files by their names, while the name is the name of the file in the database. You can use it to verify that the file was not corrupted during upload. It attempts to cast the string value passed in the PATH_INFO into an int. Nebylo-li heslo zadáno nebo jestliže jste soubor "parameters_8000.py" smazali, přístup do webového administračního rozhraní "upload" is a special type of field used by the web2py Data Abstraction Layer (DAL) to store the names of uploaded files. appadmin shows which databases are available and which tables exist in each database. Tests can be run via the admin interface. I am trying to understand how request.vars works in web2py. If you are logged-in as administrator the "wiki_editor" group is created automatically and you are made a member. web2py comes with a module gluon.contrib.webclient which allows functional testing of local and remote web2py applications. It could have been defined in the view as well. Copyright © 2020 by Massimo Di Pierro, I am now thinking of extending StringIO to write sth like response.stream(MyStringIO( [ (lengthy_op, 1), (lengthy_op, 2) ] )) but I don't feel like diving into the file interface and ending up with probably messy code if there is a solution available already. If you are a teacher and want to expose the administrative interface to students so that students can share one administrative interface for their projects (think of a virtual lab), can do it by setting: In this way students will be required to login and will only be able to access their own apps via admin. I'm very new to web2py and to web-requests so please keep a slack hand. When an action returns a dictionary, web2py looks for a view with the name. instructs web2py to use generic views (in our case "views/generic.rss") when the URL ends in the glob pattern ".rss". It allows the administrator to insert new database records, edit and delete existing records, browse tables, and perform database joins. If you create a page with slug "wiki-menu" page it will be interpreted as a description of the menu. If you click on the "shell" link under the controllers tab in edit, web2py will open a web based Python shell and will execute the models for the current application. In fact response.stream is the main download function that takes care of streaming files. Bezpečnost zvýšíte, když spustíte Web2py takto: python web2py.py -a '' -i 127.0.0.1 -p 8000. Finally, let's add an XML-RPC handler that allows searching the wiki programmatically: Here, the handler action simply publishes (via XML-RPC), the functions decorated by @ervice.xmlrpc. If python-git is installed, there is also a button to push your application to Open Shift. and executes it. If you have the SDK you may want to change these config parameters to the correct value. If there are comments, it loops over them and displays each one. Notice that message here is not a web2py keyword but is defined in the action. Components like the one above can be embedded into wiki pages using the MARKMIN syntax: This simply tells web2py that we want to include the "manage_things" action defined in the "default" controller as an Ajax "component". PyCharm or PyDev. pages. If you click on delete, you can delete the file (permanently). Because views can extend and include other views in a tree, before bytecode compilation, the view tree for every controller is collapsed into a single file. The form.accepted variable is set to True if the form was processed and passed validation. The form.process() method applies the validators and returns the form itself. Hi Guys, Does anyone know how to install matplotlib on web2py. In order to use this feature, you must have the Mercurial version control libraries installed (at least version 1.9): The Mercurial web interface does allow you to browse previous commit and diff files but we do recommend you use Mercurial directly from the shell or one of the many GUI-based Mercurial clients since they are more powerful. So to create an mjpeg stream … Now we can embed this manage_things action into any view, with. and share your web2py slices; Facebook Google. They are important for building custom forms and will be discussed later. If, for example you upload a file named "test.jpg" with title "beach", the link expression will be something like: @//// is the same prefix described before. A generic view which streams a list as a CSV for the user to open in a spreadsheet. You can also set web2py admin in demo mode: And only the apps listed in FILTER_APPS will be accessible and they will be only accessible in read-only mode. Their unnamed arguments are interpreted as objects to be serialized and inserted in the tag's innerHTML. Web2py takes care of chunked streaming via the stream() function, we just have to write a file object that we pass to stream(), this will take care of loading the jpeg frames and providing the data back to stream(), which in turn will stream this down the line to the client. In this chapter, we will discuss examples of integration of jQuery plugins with web2py. Copyright © 2020 by Massimo Di Pierro, web2py comes in binary packages for Windows and Mac OS X. I found the solution to my problem. response.stream should take a file object, not a path. Just append the following action to the default controller: you see the feed (the exact output depends on the feed reader). This is useful if you want to return the results of a database query to the user. Line 15 requires that the field "image_id" of table "post" is in db.image.id. Web2py v tomto případě použije předchozí uložené heslo. Wiki pages have URLs like: Service pages have names which start by underscore: Try to create more pages such as "index", "aboutus", and "contactus". Notice that the dict is automatically converted to RSS, thanks to the .rss extension in the URL. One of the most powerful functions of the new web2py consists in the ability of embedding an action inside another action. Finally we pass the value of the counter to the view. You can access the wizard from the "site" page as shown in the image below. If you do not provide an administrator password, the administration interface is disabled. By using the line above in your model, the wiki tables will be accessible (i.e. Notes: web2py does not know whether you actually have a debug window open in your browser; execution suspends regardless. It consists of only two files: a controller "appadmin.py" and a view "appadmin.html" which are used by all actions in the controller. This table has a field called "title", a field called "file", and a field called "id" that serves as the table primary key ("id" is not explicitly declared because all tables have an id field by default). A more compact way to code the same function is this: Now modify the view to add a line that displays the value of the counter: When you visit the index page again (and again) you should get the following HTML page: The counter is associated with each visitor, and is incremented each time the visitor reloads the page. Anyway thanks again, you've put me on the right track – mhavel Sep 22 '12 at 18:49 Alternatively we could have added the following code in the controller (inside the second function): This is an ad hoc mechanism that you can use to enforce authorization on controllers, though see Chapter 9 for a more powerful method. You can see a dropdown to select a layout plugin (from web2py.com/layouts), a multiple choice dropdown to check other plugins (from web2py.com/plugins) and a "login config" field where to put the Janrain "domain:key". Generic views are a development tool. If so you can try to use 'uploadfield' option, i.e. The wiki method has the following signature: The wiki method has some additional parameters which will be explained later: slug, env, and extra. Re: [web2py] Re: Caching downloads Edit the controller and replace the "index" action with. Start by creating a new scaffolding app, naming it "mywiki". A "download/[name]" action to download uploaded images. The net effect is that a bytecode-compiled application is faster, because there is no more parsing of templates or string substitutions occurring at runtime. The auth.wiki() function returns in a dictionary with a key content which is understood by the scaffolding "views/default/index.html". These are written respectively in the ABOUT and LICENSE files in the application folder. It allows packing the application without source code for distribution as closed source. Go directly to the application by clicking on its name. In fact, by default, generic views are only enabled from localhost. .jpg is the extension of the original file. All tickets are listed under admin in the errors page for each application: If you are running from source, the administrative interface shows one more menu item called "Versioning". If you now visit the first page, type your name: and submit the form, you will receive a greeting: The mechanism for form submission that we used before is very common, but it is not good programming practice.
