Python's rookie path: Django routing, templates, ORM

Django Routing System

The Django routing system allows Django to match the URI and send it to a specific function to process the user request. A bit like Nginx's location function.

The Django routing relationship is divided into three types: normal, dynamic, and group distribution. These three relationships are recorded in urls.py.

Routing-common Relationship

A normal relationship represents a URL that corresponds to a function, for example:

urlpatterns = [url (r '    ^admin/', admin.site.urls),    url (r ' ^login/', views.login),    url (r ' ^detail/', Views.detail),]

Routing-Dynamic Relationships

The dynamic relationship means that the dynamic matching is realized by means of regularization. For example:

Urlpatterns = [    url (R ' ^detail/(\d+)/', views.detail),  # Dynamic routing: A single-parameter routing    URL (r ' ^detail2/(\d+)/', VIEWS.DETAIL2),  # Dynamic routing: Multi-parameter Routing    URL (r ' ^detail3/(? p<p1>\d+)/(? p<x2>\d+)/', views.detail3), # Dynamic routing: named parameter, two parameters are named P1 and X2    url (r ' ^index/(\d+)/', Views.index),  # pagination display ]

Dynamic routing can also be implemented by mapping
