    <p>I am trying to create an api using django tastypie. in my project I have two models Question and Answers. The Answers model has the foreign key to question model. In my api.py I have two resources QuestionResource and AnswerResource. </p> <p>What i want to do is that when i retrieve a question instance using api call i want to retrieve the related answers instance also. I tried this using adding a key in bundle.data dict and implement it in alter_detail_data_to_serialize. bt what i get as response is a list of objects not the serialized json object. what I got is </p> <p>and my Code is </p> <pre><code> class QuestionResource(ModelResource): answer=fields.ToManyField('quiz.api.AnswerResource', 'answer', null=True, full=True) topic=fields.ForeignKey(TopicResource,'topic') difficulty=fields.ForeignKey(DifficultyLevelResource, 'difficulty') class Meta: queryset = Question.objects.all() resource_name = 'question' authorization = Authorization() serializer = PrettyJSONSerializer() detail_allowed_methods = ['get', 'post', 'put', 'delete', 'patch'] always_return_data = True filtering={'id':ALL, 'answer':ALL_WITH_RELATIONS } def alter_detail_data_to_serialize(self, request, data): data.data['answers']=[obj for obj in data.obj.answer_set.all()] return data def dehydrate(self,bundle): bundle.data['related']=bundle.obj.answer_set.all() return bundle class AnswerResource(ModelResource): question=fields.ToOneField('quiz.api.QuestionResource', 'answer', null=True,full=True) class Meta: queryset = Answer.objects.all() resource_name = 'answer' authorization = Authorization() serializer = PrettyJSONSerializer() detail_allowed_methods = ['get', 'post', 'put', 'delete', 'patch'] always_return_data = True filtering={ 'question':ALL_WITH_RELATIONS } </code></pre>

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.
