I am trying to get all the tags associated with a submission. It successfully return the list of the tags when I hit the endpoint to get all the submissions but when I hit a particular submission, I get null as the values.
this is my model
class Tag(models.Model):
title = models.CharField(max_length=50,)
def __str__(self):
return str(self.title)
class Submission(models.Model):
author = models.ForeignKey(User, on_delete=models.CASCADE)
title = models.CharField(max_length=300, null=True, blank=True)
abstract = models.TextField(null=True, blank=True)
comment_for_editor = models.TextField(null=True, blank=True)
completion_status = models.BooleanField(default=False)
tags = models.ManyToManyField("Tag", blank=True, related_name='tags')
section = models.ForeignKey("Section", on_delete=models.CASCADE, null=True, blank=True)
this is my serializer
class TagSerializer(serializers.ModelSerializer):
class Meta:
model = Tag
fields = ['title']
class startSubmissionSerializer(serializers.ModelSerializer):
files = SubmissionFilesSerializer(many=True, required=False)
tags = TagSerializer(many=True, read_only=True)
class Meta:
model = Submission
fields = ['section', 'title', 'abstract', 'comment_for_editor', 'completion_status', 'files','tags', 'id']
def create(self, validated_data):
user = self.context['user']
files = validated_data.pop('files', [])
tags = validated_data.pop('tags', None)
submission = Submission.objects.create(
author=user,
**validated_data
)
tags = str(tags['title']).split(', ')
print(tags)
for tag_title in tags:
tag, _ = Tag.objects.get_or_create(title = tag_title)
submission.tag.add(tag)
submission.save()
if files != []:
for file in files:
SubmissionFiles.objects.create(
submission = submission,
**file
)
return submission
I get back all of my submissions
[ { "section": 1, "title": "New Submission 11", "abstract": "diqgduigodui", "comment_for_editor": "hodihcioshiochiohsioc", "completion_status": false, "files": [], "tags": [ { "title": 'biology" }, { "title": "english" }, { "title": "math" }, { "title": "youtube" } ], "id": 12 }, { "section": 1, "title": "New Submission 12", "abstract": "diqgduigodui", "comment_for_editor": "hodihcioshiochiohsioc", "completion_status": false, "files": [], "tags": [ { "title": "biology" }, { "title": "english" }, { "title": "math" }, { "title": "youtube" } ], "id": 13 } ]
But i get this when i hit submission/13 { "section": null, "title": null, "abstract": null, "comment_for_editor": null }
this is my view
class SubmissionView(ModelViewSet):
"""
View your submissions
Delete one of your submission
Update one of your submission
Read one of your submission
"""
# queryset = Submission.objects.all()
serializer_class = startSubmissionSerializer
def get_object(self):
user = self.request.user
return Submission.objects.prefetch_related('tags').filter(author=user)
def get_queryset(self):
user = self.request.user
return Submission.objects.prefetch_related('tags').filter(author=user)
def get_serializer_context(self):
user = self.request.user
return {'user': user}
I was able to fix the error by removing the get_object from my view
def get_object(self):
user = self.request.user
return Submission.objects.prefetch_related('tags').filter(author=user)
