Saving test user as a foreign key in unit tests

[jondbaker]

I have a Tasting model with an 'author' field that is a ForeignKey to the User model. Within my unit test I'm attempting to create a test user, and pass that user object as the author of a test Tasting, but I keep getting the following error: "IntegrityError: tastings_tasting.author_id may not be NULL"

models.py

class Tasting(models.Model):

    notes = models.TextField(blank=True)

    author = models.ForeignKey(User, editable=False)

forms.py

class TastingForm(ModelForm):

    class Meta:

        model = Tasting

views.py

def create_tasting(request):

    if request.method =='POST':

        form = TastingForm(request.POST)

        if form.is_valid():

            form.save()

            return HttpResponseRedirect('/tastings/')

    else:

        form = TastingForm()

    return render_to_response('tastings/create.html', {

        'form': form

    }, context_instance=RequestContext(request))

test_views.py

class TestPostCreateTasting(TestCase):

    def test_auth_response_valid_data(self):

        client = Client()

        user = User.objects.create_user('test', 'te...@test.com', 'testPassword')

        client.login(username='test', password='testPassword')

        tasting = {

            'notes': 'What a great beer',

            'author': user,

        }

        response = client.post('/tastings/create/', tasting)

        self.assertEquals(response.status_code, 200)

        tastings = Tasting.objects.all()

        self.assertEquals(len(tastings), 1)

        client.logout()

Problem solved. Within my view I needed use the following:

def create_tasting(request):

    if request.method =='POST':

        form = TastingForm(request.POST)

        if form.is_valid():

            obj = form.save(commit=False)

            obj.author = request.user

            obj.save()
