Add user to authors on model save in admin form

Hi,

I'm in trouble with model admin.

I've create a CMS with Django and I try to add the last article editor, but it doesn't work if the user don't add his name in the field.

In model.py

class Article(models.Model):

                …

                author = models.ManyToManyField(User, verbose_name=u"auteur", null=True, blank=True)

                author_text = models.CharField(u'auteurs', null=True, blank=True, max_lenght=254)

 

Note: author keeps real "author" of the aritcle, author_text is editable to show another "author"

 

       def save(self, *args, **kwargs):

 

             # Si author_text est vide, le remplir avec l'auteur

             if not self.author_text and self.id:

                    author_text = list()

                    for author in self.author.all():

                           if author.first_name or author.last_name:

                                  author_name = " ".join([author.last_name, author.first_name])

                           else:

                                  author_name = author.username

                           author_text.append(author_name)

                    self.author_text = ", ".join(author_text)

In admin.py

 

       def save_model(self, request, obj, form, change):

 

             # Première sauvegarde pour attribuer un ID indispensable à un M2M

             obj.save()

             super(ArticleAdmin, self).save_model(request, obj, form, change)

 

             # Ajout de l'auteur à la liste

             if not request.user in obj.author.all() or obj.author.all() == None:

                    obj.author.add(request.user)

                    obj.save()

 

When I create a new article in admin site, author_text gets author username (as I expect with my save model), but author stay empty ! If I look at the article during "save_model", author get the user, but after "save", author is null (as in form).

How can I force author field to record the last author ? can I update admin form with a default author value ?

 

Thanks for the answer
