I have a model like this:
class Report(models.Model):
....
incident_categories = models.ManyToManyField(IncidentCategory,
through='IncidentCategoryMembership')
class IncidentCategory(models.Model):
...some properties here
class IncidentCategoryMembership(models.Model):
report=models.ForeignKey(Report, on_delete=models.CASCADE)
incident_category=models.ForeignKey(IncidentCategory,
on_delete=models.CASCADE)
comment=models.CharField(max_length=600)
This is all mapped in a viewset (for Report) that supports POST, PUT,
GET....
The update and create works fine for the nested relationship Report >
IncidentCategoryMembership > IncidentCategory
...basically I can create/update a report that has one or many categories
with a comment...
However I get a problem when I request a report and want it to return me a
report like so {id:1, ....props ,
incident_categories:[incident_category:1, comment:'some comment', ....] ...}
I get this error: 'IncidentCategory' object has no attribute
'incident_category'
serializers....
class ReportSerializer(serializers.ModelSerializer): created_by =
serializers.PrimaryKeyRelatedField(read_only=True,
default=serializers.CurrentUserDefault()) incident_categories =
IncidentCategoryMembershipSerializer(many=True)
class Meta:
model = Report
read_only_fields = ('state',)
exclude = ('locked', 'unlock_requested_by', 'marked_for_deletion_by',)
class IncidentCategoryMembershipSerializer(serializers.ModelSerializer):
incident_category = serializers.PrimaryKeyRelatedField(read_only=True)
class Meta: model = IncidentCategoryMembership fields =
('incident_category', 'comment')
Is there something obvious missing here??
