Django admin - make all fields readonly

Question

I'm trying to make all fields readonly without listing them explicitly.

Something like:

class CustomAdmin(admin.ModelAdmin):     def get_readonly_fields(self, request, obj=None):         if request.user.is_superuser:             return self.readonly_fields          return self.fields 

The problem is CustomAdmin.fields is not set at this point.

Any ideas?

Answer 1

Since django 2.1, you can prevent editing, while allowing viewing, by returning False from the ModelAdmin's has_change_permission method, like this:

class CustomAdmin(admin.ModelAdmin):     def has_change_permission(self, request, obj=None):         return False 

(This will not work before django 2.1, as it will also deny permission to any user trying only to view.)
