    <p>I recently started using tastypie to open up my api for a potential smartphone app.</p> <p><strong>I'm using python-2.7 and Django-1.1.2</strong></p> <p>Two things are confusing me</p> <p>1: in the <code>EntryResource</code> class when calling the <code>ForeignKey</code>, they just call the resource along with the resource_name, when I do it in such a way I get the following traceback.</p> <pre><code>691. assert isinstance(to, basestring), "%s(%r) is invalid. First parameter to ForeignKey must be either a model, a model name, or the string %r" % (self.__class__.__name__, to, RECURSIVE_RELATIONSHIP_CONSTANT) Exception Type: AssertionError at /api/v1/activity-stream-item-subject/ Exception Value: ForeignKey(&lt;class 'api.resources.UserResource'&gt;) is invalid. First parameter to ForeignKey must be either a model, a model name, or the string 'self' </code></pre> <p>2: if I change <code>EntryResource</code> to <code>user = fields.ForeignKey(UserResource, 'user')</code>, then it runs fine without a traceback, however I cannot see the related information in the JSON response.</p> <p>api/resources.py</p> <pre><code>class UserResource(ModelResource): class Meta: queryset = User.objects.all() resource_name = 'user' excludes = ['email', 'password', 'is_active', 'is_staff', 'is_superuser'] filtering = { 'username': ALL, } class EntryResource(ModelResource): user = fields.ForeignKey(UserResource, 'user') class Meta: queryset = Entry.objects.all() resource_name = 'entry' authorization = Authorization() filtering = { 'user': ALL_WITH_RELATIONS, 'pub_date': ['exact', 'lt', 'lte', 'gte', 'gt'], } </code></pre> <p>Any ideas?</p>

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.
