I am using Django Rest Framework for serialize data. I came across a
scenario where I have to use Database Views as Model.
*My Model*
class A(models.Model):
name = models.CharField(max_length=240, blank=True)
value = models.CharField(max_length=240, blank=True)
class Meta:
db_table = 'tbl_a'
class B(models.Model):
name = models.CharField(max_length=240, blank=True)
value = models.CharField(max_length=240, blank=True)
class Meta:
db_table = 'tbl_b'
*Database View Query*
CREATE OR REPLACE VIEW ab_view AS
SELECT id,name,value FROM tabl_a WHERE name='foo' UNION (SELECT
b.id,b.name,b.value FROM tabl_b b WHERE b.name='foo')
*Model For Database View*
class ABView(models.Model):
id = models.IntegerField(primary_key=True)
name = models.CharField(max_length=240, blank=True)
value = models.CharField(max_length=240, blank=True)
class Meta:
db_table = u'ab_view'
managed = False
*Print Text Query*
query = ABView.objects.all()print query.count() #output (1000)
When I used ABView as Model in serializer class in it shows me error
TypeError at /ViewName/ 'source' is an invalid keyword argument for this
function
class ABViewSerializer(rest_serializer.Serializer):
class Meta:
model = AbView
fields = ('name', 'value')
*View*
class ABViewSet(viewsets.ModelViewSet):
serializer_class = ABSerializer
queryset = ABView.objects.all()
Is there anything missing in this code?
Can I use Database View in Django REST Framework?
