How to connect the user model and his posts?

Question

Django

I can’t figure out how to do it, I need each post to have its own author. At the same time, so that when I added a post from the admin panel, the author could not be selected, but he was selected automatically. I found how to make it so that an authorized user is automatically inserted into the select, but if I hide the field with the user, then nothing works, and if I myself add the field with the user when adding a post to POST, it is not saved in the model.

class Publication(models.Model):
    author = models.ForeignKey(User, verbose_name=u'Автор')

class PublicationAdmin(admin.ModelAdmin):
    def save_model(self, request, obj, form, change):
        if not change:
            obj.author = request.user
        obj.save()
