4.1. ساختار اپلیکیشنها
In section ایجاد پروژه, we talked about how to create and activate a basic application in a Backendpy-based project. In this section, we describe the complete components of an application.
As mentioned earlier, a Backendpy-based application does not have a predefined structure or constraint. In fact, the developer is free to implement the desired architecture for the application and finally import and configure all the components inside the main module of the application.
The main module of an application must contain an instance of the
that is defined inside a variable called
Below is an example of defining an app with all its possible parameters (which are used to assign
components to an application):
from backendpy.app import App from .controllers.handlers import routes from .controllers.hooks import hooks from .controllers.errors import errors from .controllers.init import init_func app = App( routes=[routes], hooks=[hooks], errors=[errors], models=['project.apps.hello.db.models'], template_dirs=['templates'], init_func=init_func)
App class has the following parameters:
In the following, we will describe each of these components of the application, as well as other items that can be used in applications.
