I want a foreign key relation in my model with the username field in the User table(that stores the user created with django.contrib.auth.forms.UserCreationForm).

This how my model looks:

class Blog(models.Model):
    username = models.CharField(max_length=200) // this should be a foreign key
    blog_title = models.CharField(max_length=200)
    blog_content = models.TextField()

The username field should be the foreign key.The Foreign Key should be with this field

Unless I'm missing something, you can have a ForeignKey to a specific field:

class Blog(models.Model):
    username = models.ForeignKey(User, to_field='username')
