DJANGO ValueError: invalid literal for int() with base 10: 'admin'?

Question

Django

I'm learning Django with a video tutorial. But I ran into an error, over which I have been suffering for 4 hours, continuously googling and correcting. But to no avail.
I have DJango 1.9
In the blog application, the following is written in the models:

class Article(models.Model):
    title = models.CharField(max_length=200)
    text = models.TextField()
    user = models.ForeignKey(User)

When trying to migrate the base (migrate), it gives the following code:
ValueError: invalid literal for int() with base 10: 'admin'
In the video, everything works for him, but for me it doesn't. Already rewatched it a few times.

Answer 1

You are trying to convert 'admin' to a number somewhere.
Would you like your code to be more complete.

Answer 2

You probably already have entries in this model. Check if there are records in the database. If there is, delete it. This is just a guess, more code needed.
