Question

I have a models.py like so:

from django.db import models
from django.contrib.auth.models import User
from datetime import datetime


class UserProfile(models.Model):
    user = models.OneToOneField(User)

    def __unicode__(self):
        return self.user.username


class Project(models.Model):
    user = models.ForeignKey(UserProfile)
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)
    product = models.ForeignKey('tool.product')
    module = models.ForeignKey('tool.module')
    model = models.ForeignKey('tool.model')
    zipcode = models.IntegerField(max_length=5)

    def __unicode__(self):
        return unicode(self.id)

And my tests.py:

from django.test import TestCase, Client
# --- import app models
from django.contrib.auth.models import User
from tool.models import Module, Model, Product
from user_profile.models import Project, UserProfile


# --- unit tests --- #
class UserProjectTests(TestCase):

    fixtures = ['admin_user.json']

    def setUp(self):
        self.product1 = Product.objects.create(
            name='bar',
        )
        self.module1 = Module.objects.create(
            name='foo',
            enable=True
        )
        self.model1 = Model.objects.create(
            module=self.module1,
            name='baz',
            enable=True
        )
        self.user1 = User.objects.get(pk=1)

    ...

    def test_can_create_project(self):
        self.project1 = Model.objects.create(
            user=self.user1,
            product=self.product1,
            module=self.module1,
            model=self.model1,
            zipcode=90210
        )

        self.assertEquals(self.project1.zipcode, 90210)

But I get a TypeError: 'product' is an invalid keyword argument for this function error.

I’m not sure what is failing but I’m guessing something to do with the FK relationships…

Any help would be much appreciated.

Model.objects.create(… should likely be Project.objects.create(

At:

self.project1 = Model.objects.create(
    user=self.user1,
    product=self.product1,
    module=self.module1,
    model=self.model1,
    zipcode=90210
)

On a sidenote, naming your Model, Model, as from tool.models import Module, Model, Product seems to imply, is a bad idea.

On another sidenote, the traceback usually provides very useful information as to where the error occured. Here, you can see that the traceback indicates the error occured in:

File "/home/sam/Dropbox/django-projects/unirac/user_profile/tests.py", line 52, in test_can_create_project

Before jumping to library code, which you can reasonably expect to not be buggy.
