In Django, how do you pass a ForeignKey into an instance of a Model?

Question

I am writing an application which stores \"Jobs\". They are defined as having a ForeignKey linked to a \"User\". I don\'t understand how to pass the ForeignKey into the mode

Answer 1

A typical pattern in Django is:

1. exclude the user field from the model form
2. save the form with commit=False
3. set job.user
4. save to database

In your case:

class JobForm(forms.ModelForm):
    class Meta:
        model = Job
        exclude = ('user',)

if request.method == 'POST':
    form = JobForm(request.POST, request.FILES)
    job = form.save(commit=False)
    job.user = request.user
    job.save()
    # the next line isn't necessary here, because we don't have any m2m fields
    form.save_m2m()

See the Django docs on the model form save() method for more information.

Answer 2

Try:

if request.method == 'POST':
    data = request.POST
    data['user'] = request.user
    form = JobForm(data, request.FILES)
    if form.is_valid():
        #Do something here
