Question

I have a model for users to add time to a task.

class Time(models.Model):
    to_task = models.ForeignKey(Task)
    appuser = models.ForeignKey(CustomUser)
    hours = models.DecimalField(max_digits=5, decimal_places=2)

However when I try to create an instance of this model by using the following:

t1=Time(totask=task, appuser=user, hours=6.75)

I get an error:

TypeError: 'totask' is an invalid keyword argument for this function.

I have not made any models with multiple ForeignKeys before so am thinking that it could be because of that. However I have seen examples in the Django documentation with two ForeignKey’s and they did the exact same as I did.

After many searches I still can’t figure it out.

Answer 1

The problem is that you have define it as to_task in your model so you need to use the same name when creating an instance:

t1 = Time(to_task=task, appuser=user, hours=6.75)

Don’t forget to save it:

t1 = Time(to_task=task, appuser=user, hours=6.75)
t1.save()

You can use the create method too:

t1 = Time.objects.create(to_task=task, appuser=user, hours=6.75)
