    <p>Im looking to create a view in the admin panel for a test program which logs Books, publishers and authors (as on djangoproject.com)</p> <p>I have the following two models defined.</p> <pre><code>class Author(models.Model): first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) email = models.EmailField() def __unicode__(self): return u'%s %s' % (self.first_name, self.last_name) class Book(models.Model): title = models.CharField(max_length=100) authors = models.ManyToManyField(Author) publisher = models.ForeignKey(Publisher) publication_date = models.DateField() def __unicode__(self): return self.title </code></pre> <p>What I want to do, is change the Book model to reference the first_name of any authors and show this using admin.AdminModels. </p> <pre><code>#Here is the admin model I've created. class BookAdmin(admin.ModelAdmin): list_display = ('title', 'publisher', 'publication_date') # Author would in here list_filter = ('publication_date',) date_hierarchy = 'publication_date' ordering = ('-publication_date',) fields = ('title', 'authors', 'publisher', 'publication_date') filter_horizontal = ('authors',) raw_id_fields = ('publisher',) </code></pre> <p>As I understand it, you cannot have two ForeignKeys in the same model. Can anyone give me an example of how to do this?</p> <p>I've tried loads of different things and its been driving me mad all day. Im pretty new to Python/Django.</p> <p>Just to be clear - I'd simply like the Author(s) First/Last name to appear alongside the book title and publisher name. </p> <p>Thanks</p>

    1. CONot sure the answer to your question but "you cannot have two ForeignKeys in the same model" isn't a true statement. I also think you are confusing Foreign Keys with the __unicode__() function.

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.
