Application Object

There can only be one instance of a diva.core.Application per Python interpreter. That is because the application is in many places accessed via the app singleton, which provides thread-local access to the application context.

Usually a specific application will define a subclass of diva.core.Application that is explicitly instantiated at startup:

>>> from diva.core import Application
>>> 
>>> class MyApp(Application):
...    pass
... 
>>> myapp = MyApp()

After this point, you'll be able to access the singleton instance of the application using a simple import:

>>> from diva import app
>>> app
<diva.ApplicationProxy object at …>

This application proxy forwards all operations to the actual application class. The application class has a ctxt property that provides access to various thread-local objects, such as the current HTTP request.
