I have two generic class based views, CreateView and UpdateView.
I have products and companies, where a company can have multiple products.
A user has a company.
When a product is added I need to send also the corresponding foreign key
and when I edit/update I need to be sure that the product update belongs to
the company of the user.
Code:
1. Create
*def *form_valid(self, form):
company = self.get_company()
form.instance.company = company
valid_data = super(ProductCreateView, self).form_valid(form)
*return *valid_data
2. Update
*def *get_object(self, *args, **kwargs):
company = self.get_company()
obj = super(ProductUpdateView,self).get_object(*args, **kwargs)
*if *obj.company == company:
*return *obj
Why for create the instance is use (form.instance.company = company) and on
update the object is requested ? (I have general knowledge about OOP)
