Notice that everywhere admin shows syntax-highlighted code (for example, in error reports, web2py keywords are shown in orange). Here is an example: Each line a menu item. The generated SQL is logged into "sql.log". The key smartgrid_args is passed to the smartgrid used to edit or view the tables. We will call this application "myapp".
Similarly, auth.user_groups contains a dictionary where each key is the id of a group of with the current logged in user is member of, the value is the corresponding group role.

First of all we need to modify the web2py application and add the following controller: which returns true if the user is logged in and false otherwise.

The web2py admin includes a web-based debugger.

You can select a different set of records by editing the DAL query and pressing [Submit]. The first argument, "image", is the name of the table we are defining. All input should be validated and, in the above example, the burden of validation would fall on the second action. Edit this new file and replace its content with the following: This view displays the image.file by calling the "download" action inside an tag. For the next example we will use DroidOTP. By default the user will 3 attempts to introduce the code. How to do this is browser-dependent, but probably you are more likely to use certificates for web services. Notice that this will prevent a visitor from logging in but it will not force a visitor who is already logged in to log out. The wizard will guide you through a series of steps involved in creating a new application: The image below shows the second step of the process.

Google, Twitter, Facebook and so on, all have APIs that can be easily accessed by a web2py application. The administrative interface provides additional functionality that we briefly review here. and executes it.

You can register with Janrain.com, register a domain (the name of your app) and set of URLs you will be using, and they will provide you with an API key. The names of the table can be changed by reassigning the above variables after the auth object is defined and before the Auth tables are defined. 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". This feature of web2py is called "internationalization" and it is described in more detail in the next chapter. If, instead, .captcha is set to None, only those form who have a corresponding option set to a gluon.tools.Recaptcha object will have captcha and the others will not. We used double dash for nested menu items. To limit access to authenticated users, we need to complete three steps.

Every time the visitor releases a key, the JavaScript code inside the onkeyup attribute is executed, client-side. It simply removes the byte-code compiled models, views and controllers from the application. There is one exception to this log off and log in process which is in case that the user change his own membership, in this case auth.user_groups can be properly update for the actual connected user because web2py has access to the proper session user_groups variable. This easily gives errors, especially if you play with databases creation and connections. For example, an access control list could be used to grant or deny write access to a particular system file, but it would not dictate how that file could be changed.". The administrator can switch between the two views. A "download/[name]" action to download uploaded images. If the user is not authenticated, the controller redirects the visitor from the CAS appliance, where the user can log in, register, and manage his credentials (name, email and password). Applications seeking to authenticate visitors are called service consumers. In multi user mode, you can register students using the "bulk register" link in admin and manage them using the "manage students" link. You can use the web2py Role Base Access Control and authenticate with other services like OpenID, Facebook, LinkedIn, Google, Dropbox, MySpace, Flickr, etc. How to do it is web server dependent and therefore omitted here. The items in the drop-down are stored as keys (db.image.id), but are represented by their db.image.title, as specified by the validator.

Notice the API of the built-in wiki is still considered experimental and small changes are still possible.

After you login into admin you can edit the admin configuration file via the URL: Notice that admin can be used to edit itself. This returns a tar file containing a complete copy of the application. 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.

For example, if your office IP is 93.56.854.54 and you don't want two-factor authentication from your office IP. The MARKMIN syntax allows you to markup bold text using **bold**, italic text with ''italic'', and code text should be delimited by double inverted quotes. The session is a container for variables that are stored server-side. The attribute requires allows you to set requirements/constraints that will be enforced by web2py forms.

Here are some examples: The condition argument of @auth.requires(condition) can be a callable and unless the condition is simple, it better to pass a callable than a condition since this will be faster, as the condition will only be evaluated if needed.

In particular you need to tell your web server where the certificates are located on local host and that it needs to verify certificates coming from the clients. Clicking on "administrative interface" takes you to the login page for the administration interface. Once they have been created, web2py provides an API to check if a user is logged in, if a user is a member of a given group, and/or if the user is a member of any group that has a given required permission. Now you have a copy of the welcome application. Applications created with the wizard and edited manually, cannot later be modified by the wizard. Some times you want to implement your own logic and do "manual" user login. The above examples (which are the default values) should, however, work in most cases.

The keys of the items in the dictionary are interpreted as variables passed to the view associated to the action. Otherwise it will render the normal login form together with the other_form. If you fix the divide-by-zero bug in the index action and introduce one in the index view: Note that web2py has converted the view from HTML into a Python file, and the error described in the ticket refers to the generated Python code and NOT to the original view file: This may seem confusing at first, but in practice it makes debugging easier, because the Python indentation highlights the logical structure of the code that you embedded in the views. An example is LDAP. This page lists all installed web2py applications and allows the administrator to manage them. The condition can be a boolean value or a function evaluating to boolean.
The difference between editors and authors is that the editors can create pages, edit and delete any page, while the authors can create pages (with some optional restrictions) and can only edit/delete the pages they have created. You can use it to verify that the file was not corrupted during upload. The admin interface also provides a page where you can translate each string in the languages you desire to support. There is no need to call.

Edit the "index" function as follows: Here is what the online editor looks like: Save it and go back to the edit page. The new copy is not. First of all you must install the Facebook Python SDK.

web2py provides support for third party authentication and single sign on. appadmin can also perform joins if the query contains a SQL condition that involves two or more tables. You can see the generated SQL from the edit page by clicking on the "sql.log" link under "models". More complex examples will be discussed later.

It tracks the time as a running total of seconds. This wiki can be used with any web2py application.

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). It is good practice to do this for every string in the code (field labels, flash messages, etc.)

You should be able to customize strings without editing the code and in particular insert translations for these strings in different languages. If the visitor is not logged in, then the permission cannot be checked; the visitor is redirected to the login page and then back to the page that requires permissions.
