Django Views and URLs

• A view dictates what information is shown to the client, while a URL dictates where that information is shown on the website.
• A view and URL work together to create a specific web page on a website.
• A view can't function alone and needs to be routed through a URL.
• Not every permutation of a web page can be known in advance, so Django views and URLs support dynamic and logic features.

Dynamic URLs

• Dynamic URLs can handle unknown information, such as the number of blog posts on a website.
• Instead of hardcoding URLs, Django can create dynamic URLs that adapt to new content.

urls.py Files

• There are two main urls.py files: one at the project level and one at the app level.
• Multiple apps can have multiple urls.py files.
• The view is connected to the URL through the use of path and include Django functions.

URL Patterns

• A list of view routes is defined in a list variable called URL patterns.
• URL patterns are used to connect a view to a URL.

Connecting Views to URLs

• A view is connected to a URL using a path function call.
• The first argument in a path function call is the actual route (URL pattern).
• Django scans the relevant URL patterns list until it finds a matching string route.
• The second required argument in a path function call is the actual view.

Path Function Call Arguments

• The path function call has two required arguments: the route (URL pattern) and the view.
• The view argument connects to a function or view defined in the views.py file or the relevant Django app.
• There are two optional arguments: keyword arguments (passed as a dictionary to the view) and name (allows referencing a URL elsewhere in Django).
