How do I correctly configure nested urls.py for both plural and singular URL paths in Django?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm trying to set up the following URL routing in my Django project:

• example.com/recipes → List of recipe categories
• example.com/recipes/soups → List of recipes for a certain category (e.g., soups)
• example.com/recipe/lentil-soup → Specific recipe detail (note the singular 'recipe' in the URL)

This works well at the project root level, but I’m having trouble configuring nested URL patterns. Here’s what I’ve tried:

PYTHON
# mysite/mysite/urls.py
urlpatterns = [
    re_path(r'^recipes?/', include('recipes.urls')),
] 
PYTHON
# mysite/recipes/urls.py
urlpatterns = [
    re_path(r'^/?$', views.categories, name="categories"),
    re_path(r'^(?P<url_name>[\-_a-z0-9]+)/?$', views.category, name='category'),
    re_path(r'^(?P<url_name>[\-_a-z0-9]+)/?$', views.recipe, name='recipe'),
]

Two issues arise from this approach:

  1. The pattern "^recipes?/$" at the root matches example.com/recipes/ but not example.com/recipes, and changing it to "^recipes?/?$" causes more specific patterns to incorrectly join parameters (e.g., resulting in example.com/recipessoups).
  2. The second and third patterns in the nested urls.py are indistinguishable because I cannot differentiate between the plural category and the singular recipe URL segments.

Should I define all three patterns at the root urls.py, or is there a way to achieve this nested configuration correctly?

Django URL Configuration for Recipe Site

Based on your requirements, I recommend defining separate URL patterns at the root level rather than trying to use a regex with recipes?/ which is causing confusion. Here's a better approach:

Solution

Project-level URLs (mysite/mysite/urls.py)

PYTHON
from django.urls import path, include

urlpatterns = [
    path('recipes/', include('recipes.urls.categories')),
    path('recipe/', include('recipes.urls.recipes')),
]

App-level URLs (mysite/recipes/urls/categories.py)

PYTHON
from django.urls import path
from recipes import views

urlpatterns = [
    path('', views.categories, name='categories'),
    path('<slug:url_name>/', views.category, name='category'),
]

App-level URLs (mysite/recipes/urls/recipes.py)

PYTHON
from django.urls import path
from recipes import views

urlpatterns = [
    path('<slug:url_name>/', views.recipe, name='recipe'),
]

Explanation

  1. This approach clearly separates the plural "recipes" routes from the singular "recipe" routes.
  2. Using Django's path() function instead of re_path() makes the code more readable and maintainable.
  3. The slug path converter is used instead of a regex pattern for URL names, which is cleaner.
  4. By organizing the URLs into separate files, you maintain better separation of concerns.

This configuration will correctly handle:

  • example.com/recipes/ → List of recipe categories
  • example.com/recipes/soups/ → List of recipes in the "soups" category
  • example.com/recipe/lentil-soup/ → Detail page for the "lentil-soup" recipe

Note that Django will automatically handle trailing slashes based on your APPEND_SLASH setting, so you don't need to worry about explicitly handling both /recipes and /recipes/ in your patterns.

If you prefer to keep all URL patterns in a single file, you can also use this approach:

PYTHON
# mysite/mysite/urls.py
from django.urls import path
from recipes import views

urlpatterns = [
    path('recipes/', views.categories, name='categories'),
    path('recipes/<slug:url_name>/', views.category, name='category'),
    path('recipe/<slug:url_name>/', views.recipe, name='recipe'),
]

This is simpler and achieves the same result without nested URL configurations.
