How to load an instance in class based views using form_valid
Sam Hefer
I'm trying to build a form that automatically fills some fields in a class based create view that lets logged in users create a Job. However, I can't seem to find the correct way of doing this for fields that aren't the user (eg. request.user).
So the create view is trying to get a company_name from the logged in user, company_name field belongs to a model called Company. Each Company has an owner with a foreign key to the User model. All the reuest I've tried so far have led to a 'WSGIRequest' error.
So far I've tried to request: company_name user.company_name company.company_name company user
I don't understand how these requests work, I have seen examples for getting the logged in users name and I'm not familiar how to do this otherwise.
Please can someone help me understand how this works and how I should be doing this?
I'm using Django 2.2 with python 3.6
