How to check model with foreign key in django?

Question

I am using python 3.5 and Django 1.10 and trying to test my application in test.py, but I got an error: "t20> so how to check the fk value here? Here is the code:

class NewsletterModelTest(TestCase):

    @classmethod
    def setUpTestData(cls):
        #Set up non-modified objects used by all test methods
        NewsLetter.objects.create(NewsLetterID=1, Email='[e-mail]', Connected=False,UserID=1)


    class NewsLetter(models.Model):
         NewsLetterID = models.AutoField(primary_key=True)
         Email = models.CharField(max_length=255)
         Connected = models.BooleanField(default=False)
         UserID = models.ForeignKey(User, on_delete=models.CASCADE)
         class Meta:
              db_table = 'NewsLetter'

Answer 1

In your setupTestData method, you need to create a User object in order to pass it in the NewsLetter object creation method.

@classmethod
def setUpTestData(cls):
    #Set up non-modified objects used by all test methods
    user = User.objets.create(<fill params here>)
    NewsLetter.objects.create(NewsLetterID=1, Email='[e-mail]', Connected=False,UserID=user)
