Cheat sheet
- Import Necessary Modules:
from django.urls import path, re_path, include
2. path() is used for almost all URL patterns:
path('route/', view_function, name='name_of_url')
3. Include urls from other apps in your project
path('app_name/', include('app_name.urls'))4. Assigning names to url patterns For easy referencing
path('route/', view_function, name='name_of_url')
5. Passing parameters to Django views
path('route/<int:param>/', view_function, name='name_of_url')6. Avoid conflicts with app_name namespaces
app_name = 'app_name'
urlpatterns = [
# ...
]
7. URL pattern order
URL patterns are matched in the order they appear, so place more specific patterns before generic “Catch-all” ones.
8. Catch-all for homepages
from django.urls import path
from . import views
urlpatterns = [
path('', views.home_view, name='home'),
]
9. Trailing slashes
By default, Django automatically appends a trailing slash to URLs. Use APPEND_SLASH = False in settings.py to disable this behavior.
10. Using Django’s Built-in Views:
By default, ListView retrieves all objects of the specified model:
from django.views.generic import ListView
from .models import Article
class ArticleListView(ListView):
model = Article
template_name = 'article_list.html' # Define the template for displaying the list of articles
context_object_name = 'articles' # Define the variable name for the list of objects in the template
paginate_by = 10 # Specify the number of items to display per page
