I was going through “Step 4. Creating and Running Your First Django Project” at:
And the "Creating models" code seems to causes an error:
File "C:\Users\nick\PycharmProjects\Step4\polls\models.py", line 25, in Choice
question = models.ForeignKey(Question)
TypeError: __init__() missing 1 required positional argument: 'on_delete'
I looked into why, and apparently in Django 2.0 and after, the on_delete parameter is now required:
So, if you go back to the page, under the “Creating models” section:
The Choice class needs to be changed to include the on_delete parameter, perhaps something like what I have below:
question = models.ForeignKey(Question, on_delete=models.DO_NOTHING, )
choice_test = models.CharField(max_length=200)
votes = models.IntegerField(default=0)
I apologize if this isn’t the right place to post this, but hopefully this will help someone else new to Python/PyCharm and/or it’ll get noticed and fixed.
