    <p>I am using django-rest-framework to build out the back end. I have the list running fine, but (using the django-rest-framework admin screen) I cannot create an object by just using the Id fields of the foreign key objects. I hope I have this configured incorrectly, but I am open to writing some code if i have to :) I am learning django/python from a .NET and Java background and may have become a touch spoiled by this new stack.</p> <p><strong>Edit: I am trying not to use two different Model classes- I shouldn't have to right?</strong></p> <p>Thanks in advance.</p> <p>From Chrome - the key bits of the request</p> <pre><code>Request URL:http://127.0.0.1:8000/rest/favorite_industries/ Request Method:POST _content_type:application/json _content:{ "user_id": 804 ,"industry_id": 20 } </code></pre> <p>The response</p> <pre><code>HTTP 400 BAD REQUEST Vary: Accept Content-Type: text/html; charset=utf-8 Allow: GET, POST, HEAD, OPTIONS { "user": [ "This field is required." ] } </code></pre> <p>Ugh. Here are the key classes from django:</p> <pre><code>class FavoriteIndustry(models.Model): id = models.AutoField(primary_key=True) user = models.ForeignKey(User, related_name='favorite_industries') industry = models.ForeignKey(Industry) class Meta: db_table = 'favorites_mas_industry' class FavoriteIndustrySerializer(WithPkMixin, serializers.HyperlinkedModelSerializer): class Meta: model = myModels.FavoriteIndustry fields = ( 'id' , 'user' , 'industry' ) </code></pre> <p><strong>Edit Adding the viewset:</strong></p> <pre><code>class FavoriteIndustriesViewSet(viewsets.ModelViewSet): #mixins.CreateModelMixin, viewsets.GenericViewSet): paginate_by = 1 queryset = myModels\ .FavoriteIndustry\ .objects\ .select_related() print 'SQL::FavoriteIndustriesViewSet: ' + str(queryset.query) serializer_class = mySerializers.FavoriteIndustrySerializer </code></pre> <p>The get/list functionality generates decent JSON:</p> <blockquote> <p>{"count": 2, "next": "<a href="http://blah.com/rest/favorite_industries/?page=2&amp;format=json">http://blah.com/rest/favorite_industries/?page=2&amp;format=json</a>", "previous": null, "results": [{"id": 1, "user": "<a href="http://blah.com/rest/users/804/">http://blah.com/rest/users/804/</a>", "industry": {"industry_id": 2, "industry_name": "Consumer Discretionary", "parent_industry_name": "Consumer Discretionary", "category_name": "Industries"}}]}</p> </blockquote>

    2. COIt is shared that's all the code I am using django-rest-framework. Wait there is the viewSet but I don't see how it is important. Basically the url is routed to the viewSet and the REST is magic :)

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.
