Django Admin - Disable the "Add" action for a specific model

📝 Django Admin - Disable the 'Add' action for a specific model

Are you facing issues with the Django admin 'Add' action for a specific model? Do you want to disable the 'Add' functionality and display a custom error message or a 404 page instead? In this blog post, we'll address this common issue and provide you with easy solutions to tackle it.

🔍 Understanding the Problem

The problem arises when you have a Django site with various models, forms, formsets, inlineformsets, custom validations, and querysets. In this scenario, the 'Add' action in the Django admin throws a 500 error due to dependencies on other forms.

🤔 The Question

Is there any way to disable the 'Add $MODEL' functionality for certain models? How can we make sure that the '/admin/appname/modelname/add/' URL returns a 404 or a suitable error message? Moreover, how do we remove the 'Add $MODELNAME' button from the '/admin/appname/modelname' view?

💡 Easy Solutions

1. Override get_urls() method: One way to achieve this is by overriding the get_urls() method in your model's admin class. By doing so, you can modify the URL patterns and return a 404 response for the 'add' URL. Here's an example:

   from django.http import Http404 class YourModelAdmin(admin.ModelAdmin): def get_urls(self): urls = super().get_urls() custom_urls = [ path('add/', self.admin_site.admin_view(self.add_view)), ] return custom_urls + urls def add_view(self, request): raise Http404("Custom error message or redirect to a suitable page.")

   This approach allows you to handle the 'Add' action for your model and display a custom error message or redirect the user to a different page.

2. Remove 'add' URL pattern: Another approach is to remove the 'add' URL pattern altogether. You can do this by specifying a custom ModelAdmin without the add_view in the URL configuration. Here's an example:

   from django.contrib import admin from django.urls import path, re_path from django.http import Http404 # Custom model admin without the 'add' view class YourModelAdmin(admin.ModelAdmin): # Your custom admin configurations # URL patterns urlpatterns = [ # Other URL patterns re_path(r'^admin/appname/modelname/', include(([ # Remove 'add' URL pattern re_path(r'^$', YourModelAdmin.as_view(), name='modelname_changelist'), ], 'appname'), namespace='appname')), ]

   This approach removes the 'Add' button from the '/admin/appname/modelname' view and handles any attempt to access the 'add' URL.
