following:
|
|
|
|
* Icon for the app
|
|
* Name of the app
|
|
* Description of the app
|
|
* Link to the manual page for the app

* A button to enable/disable the app

'app_id' is the mandatory property to set the ID of the app. It is used to

retrieve the App instance for the app that is needed for basic information
|
|
and operations such as enabling/disabling the app.
|
|
|
|
'form_class' is the Django form class that is used by this view. By default
|
|
the AppForm class is used.
|
|
|
|
'show_status_block' is a boolean to determine if the status section must be
|
|
shown in this app's page.
|
|
|
|
'template_name' is the template used to render this view. By default it is
|
|
app.html. It may be overridden with a template that derives from app.html
|
|
to customize the appearance of the app to achieve more complex presentation
|
|
instead of the simple appearance provided by default.
|
|
|
|
'port_forwarding_info' is a list of port information dictionaries that can
|
|
used to show a special section in the app page that tells the users how to
|
|
forward ports on their router for this app to work properly.
