    <p>I have a threaded mptt comments model to use with my BlogItem model:</p> <pre><code>class MyComment(MPTTModel, Comment): parent = TreeForeignKey('self', null=True, blank=True, related_name='children') class MPTTMeta: order_insertion_by=['-submit_date'] class Meta: ordering=['tree_id','lft'] </code></pre> <p>For tastypie i made Resource</p> <pre><code>class MyCommentResource(ModelResource): # i tried to use this commented strings (and of course i created related resources) #comment = fields.ForeignKey(CommentRosource, 'comment', null=True, full=True) #site = fields.ForeignKey(SiteResource, 'site', null=True, full=True) #content_type = fields.ForeignKey(ContentTypeResource, 'content_type', null=True, full=True) #children = fields.ToManyField('self', 'children', null=True, full=True) #content_object = GenericForeignKeyField({BlogItem: BlogItemResource}, 'content_object', null=True, full=True) class Meta: queryset = MyComment.objects.filter(level=0) resource_name = 'myComment' include_resource_uri = False allowed_methods = ['get', 'post', 'put'] include_resource_uri = False filtering = { 'object_pk': ALL, 'level': ALL } authorization= Authorization() </code></pre> <p>After that i have working api for GET requests fo MyComment model (i can see all comments (commenter's name, comment text, mptt level, pagination etc)</p> <p>But when i try to make curl (or js) erquest:</p> <pre><code>curl --dump-header - -H "Content-Type: application/json" -X POST --data '{"comment":"sdfsdfsdf"}' http://myhostname.com:80/api/v1/myComment/ &gt; /tmp/err.html </code></pre> <p>I get error "current transaction is aborted, commands ignored until end of transaction block" or other errors ("DoesNotExist at /api/v1/myComment/ No exception supplied", "Cannot assign None: "MyComment.content_type" does not allow null values." - but in request i POST {"content_type":{"id":"15"}} or link to content_type in my api that also works great).</p> <p>For other, more simpler models (without generic relation, but with ForeignKeys) i can make curl requests and get "201 created" response, so i think i have error related to "generic" comments model</p> <p>I'm doing wrong? Is there any docs or manuals - how to create object for "generic" model via tastypie?</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.
