Re: Automatically assign model instance to the user who created it. And only that user can edit/delete the instance.

Thanks for your response.  This is an off-topic question but I can't figure out how to get 'request' working.  I'm using the CreateView generic class, so there's no space to insert 'request'.  This is what my code looks like.  When I try to run it, it tells me that request is not found.  

class ListingCreateView(LoginRequiredMixin, CreateView):

    model = BuyerListing

    

    form_class = PostListing(self.request.POST)

    if form.is_valid():

        form_save = form.save(commit=False)

        form_save.user = request.user # user is logged in

        form.save()

        

    def get_queryset(self):  # the user want to edit this post must be owner this post

        post_qs = super(PostListing, self).get_queryset()

        return post_qs.filter(user=self.request.user)

try that in your views

form = Dog_Form(request.POST)
if form.is_valid():
    form_save = form.save(commit=False)
    form_save.user = request.user # user is logged in
    form.save()

Let's say I have a model called 'Dogs'.  Users can create instances of Dogs.  Let's say we have a user called User1.  I have 2 questions:

1. When User1 creates an instance of Dogs, how do I automatically assign that instance to User1?  I tried using a model field like this but it doesn't pick the user automatically:

user = models.ForeignKey(User, unique=False)

2. After the instance has been created, how do I make the instance only editable and removable by the user who made it?  Basically, if User1 creates an instance of Dogs, only User1 can edit and delete that instance. 

Thanks.
