    <p>From <a href="https://docs.djangoproject.com/en/dev/ref/contrib/admin/#working-with-many-to-many-intermediary-models" rel="nofollow">https://docs.djangoproject.com/en/dev/ref/contrib/admin/#working-with-many-to-many-intermediary-models</a></p> <blockquote> <p>When you specify an intermediary model using the through argument to a ManyToManyField, the admin will not display a widget by default. This is because each instance of that intermediary model requires more information than could be displayed in a single widget, and the layout required for multiple widgets will vary depending on the intermediate model.</p> </blockquote> <p>However, you can try including the tags field explicitly by using <code>fields = ('tags',)</code> in admin. This will cause this validation exception </p> <blockquote> <p>'QuestionAdmin.fields' can't include the ManyToManyField field 'tags' because 'tags' manually specifies a 'through' model.</p> </blockquote> <p>This validation is implemented in <a href="https://github.com/django/django/blob/master/django/contrib/admin/validation.py#L256" rel="nofollow">https://github.com/django/django/blob/master/django/contrib/admin/validation.py#L256</a></p> <pre><code> if isinstance(f, models.ManyToManyField) and not f.rel.through._meta.auto_created: raise ImproperlyConfigured("'%s.%s' " "can't include the ManyToManyField field '%s' because " "'%s' manually specifies a 'through' model." % ( cls.__name__, label, field, field)) </code></pre> <p>I don't think that you can bypass this validation unless you implement your own custom field to be used as ManyToManyField. </p>

    1. COAnother possibility would be to tag the date_added field as read_only, which will allow `ModelAdmin` to pass validation. Obviously, you can't use this if you expect to modify `date_added` at a later point, but from your logic it doesn't seem you will have to.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
