What would you like to do?
Read-only ModelAdmin for Django
from django.contrib import admin
class ReadOnlyModelAdmin(admin.ModelAdmin):
ModelAdmin class that prevents modifications through the admin.
The changelist and the detail view work, but a 403 is returned
if one actually tries to edit an object.
actions = None
# We cannot call super().get_fields(request, obj) because that method calls
# get_readonly_fields(request, obj), causing infinite recursion. Ditto for
# super().get_form(request, obj). So we assume the default ModelForm.
def get_readonly_fields(self, request, obj=None):
return self.fields or [ for f in self.model._meta.fields]
def has_add_permission(self, request):
return False
# Allow viewing objects but not actually changing them.
def has_change_permission(self, request, obj=None):
return (request.method in ['GET', 'HEAD'] and
super().has_change_permission(request, obj))
def has_delete_permission(self, request, obj=None):
return False

Have you ever tried doing a model readonly conditionally?
def has_delete_permission(self, request, obj): if obj.status == 'done': return False return True
