Access to user's email

Question

I want to put the email of user in my model Article.

from django.db import models
from django import forms
from django.contrib.auth.models import User
 class Article(models.Model):
 #auteur
 email = models.ForeignKey(User.email, unique=True)
 name = models.CharField(max_length=200)
 #titre
 title = models.CharField(max_length=200)
 title_en = models.CharField(max_length=200)
 subtitle = models.CharField(max_length=200)
 subtitle_en = models.CharField(max_length=200)

Answer 1

What you have written has no sense. You have to keep a ForeignKey on the user, and then access to his email through user.email:

class Article(models.Model):
 #auteur
 user = models.ForeignKey(User, unique=True)
 #titre
 title = models.CharField(max_length=200)
 title_en = models.CharField(max_length=200)
 subtitle = models.CharField(max_length=200)
 subtitle_en = models.CharField(max_length=200)

Then, Article.user.username (or self.user.username inside an Article method) gives you the name and Article.user.email the e-mail.

Some explanations

In Django, you can create ForeignKey only on Model object, and not object field. This will be translate in SQL as a classic reference between tables. (If you check your Article SQL database, you'll see a user_id field. This field will contains the ID of the user, extract from the auth_user table, which created the Article.
