Is it possible to display many to many links for two models in the django admin panel? Models are in different applications.

What I was trying to do.

library.models:

from article.models import Articles, ArticlesDocuments class Documents(models.Model): ... article = models.ManyToManyField(Articles, through='ArticlesDocuments', blank=True)

article.models:

 from library.models import Documents class Articles(models.Model): ... document = models.ManyToManyField(Documents, through='ArticlesDocuments', blank=True) class ArticlesDocuments(models.Model): article = models.ForeignKey(Articles) document = models.ForeignKey(Documents) class Meta: db_table = 'article_articles_documents' auto_created = Articles

But it does not work, it gives an error: ImportError: cannot import name 'Articles'

As I understand it, this is because Documents have already been imported into article.models. How to be? Thanks in advance for your reply.

  • Try importing from article import models as aModels as from article import models as aModels . And then use aModels.Articles - betonimig

library.models

 class Documents(models.Model): ... article = models.ManyToManyField('article.Articles', through='article.ArticlesDocuments', blank=True)

article.models

 class Articles(models.Model): ... document = models.ManyToManyField('library.Documents', through='ArticlesDocuments', blank=True) class ArticlesDocuments(models.Model): article = models.ForeignKey(Articles) document = models.ForeignKey('library.Documents') class Meta: db_table = 'article_articles_documents' auto_created = Articles

Instead of quoting the Django documentation to explain why this works, just leave a link to the appropriate section: ForeignKey
