Your Django app is just an ordinary python package. The models in one app knows nothing about other models. For one model to inherit from another model in a different app, you have to explicitly import and subclass accordingly.

I have authenticated id and pass from database from x model and while id and password user enters should match with it but in views it does not matches

Pls help me anyone

If you are trying to create a role or user in your PostgreSQL database, kindly note that initdb automatically creates a role called postgres. You cannot have two roles with the same name in the same database just like it applies to tables

so how I can create user and connect to my django project?

You can create a user at the terminal using createsuper, at the admin interface, calling your User.objects.create() or using forms

i added in the base directory but it's still not extending

1 check urls.py (make sure you call the path is 100% correct) 2 make you your base.html is in template destination following settings.py

i added in the base directory but it's still not extending

To extend another template, {% extends <template_name> %} must be topmost of your template and that template should be in the directory

Do you know how to connect with postgresql credential ?

I trying that and : postres@ createsuperuser : command not found

and I dont know how to creare user for my postgresql after install that

After installing PostgreSQL in your machine run this commands: pg_ctl -D <the directory you want your db cluster> initdb createdb <name of db> The name you use at createdb should be passed to NAME parameter in your Django DATABASE setting

You must start the postgres server before running your local Django server that depends on it

Celery tasks serialize data passed as argument for example you cannot pass request object

No,this need to be in json format then only can be send to background task. I will share the code for more clarity.

You shouldn't pass an entire object to a task. You can simply pass a list of ids. Then in your task def task(image_ids): Image.objects.filter(id__in=image_ids)
