Ionic/AngularJS POST request to Django - angularjs

Question

I have a model "Interview" and a model "Notes". Interview is a foreign key of Notes.
class Notes(models.Model):
notes = models.TextField(null=True)
interview = models.ForeignKey(Interview, null=True)
def __str__(self):
return self.interview
I am using http requests to GET and POST to the server.
How can I post notes to the server exactly since interview is a foreign key? Currently my post function looks like this:
saveNotes: function(interview, notes) {
$http({
method: 'POST',
url: apiroute + '/notes',
data: {
"notes": notes,
"interview": {
//attr of interview
}
}
}).success(callback);
}
And this looks to be correct but I am being met with:
POST http://127.0.0.1:8000/app/api/notes 500 (INTERNAL SERVER ERROR)
I used "notes/" as my url and I got:
POST http://127.0.0.1:8000/student/api/notes/ 400 (BAD REQUEST)
Can someone give a guess as to what my issue might be?
Thanks!
EDIT: Here are my serializer files. Interview is replaced by Lecture
class LectureSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = Lecture
fields = ('id', 'lecture_no', 'title', 'youtubeLink', 'course', 'keywords')
class NotesSerializer(serializers.HyperlinkedModelSerializer):
lecture = LectureSerializer(read_only=True, many=True)
class Meta:
model = Notes
fields = ('id', 'notes', 'lecture')
api views:
class LectureViewSet(viewsets.ModelViewSet):
serializer_class = LectureSerializer
def get_queryset(self):
course_id = self.request.query_params.get('course',False)
if course_id:
lectures = Lecture.objects.filter(course=course_id)
else:
lectures = Lecture.objects.all()
return lectures
class NotesViewSet(viewsets.ModelViewSet):
queryset = Notes.objects.all()
serializer_class = NotesSerializer

Answer 1

you need only to send the interview_id value:
data: {
"notes": notes,
"interview_id": interview_id
}
and in serializers.py define your serializers as follow:
class InterviewSerializer(serializers.ModelSerializer):
class Meta:
model = Interview
class NoteSerializer(serializers.ModelSerializer):
interview = InterviewSerializer(read_only=True, many=True)
class Meta:
model = Note
