Upload multiple images and link them to property
I am using django rest framework for rest api. I am trying to work with loading multiple images and linking those multiple images to property. However, my viewable api does not show the form to upload images, so I can check if my code is working or not. How do I upload multiple images and link them to a property?
class Property(models.Model):
owner = models.ForeignKey(settings.AUTH_USER_MODEL)
address = models.CharField(_('Address'), max_length=140)
rooms = models.PositiveSmallIntegerField(_('Rooms'))
class Gallery(models.Model):
property = models.ForeignKey(Property, related_name="gallery")
caption = models.CharField(null=True, blank=True, max_length=80)
image = models.ImageField(upload_to="properties/rooms/")
class GallerySerializer(serializers.ModelSerializer):
class Meta:
model = Gallery
fields=('id', 'caption', 'image', )
class PropertySerializer(serializers.ModelSerializer, EagerLoadingMixin):
_SELECT_RELATED_FIELDS = ['owner', ]
_PREFETCH_RELATED_FIELDS = ['property_type',]
gallery = GallerySerializer(many=True)
class PropertyGallery(APIView):
serializer_class = GallerySerializer
parser_classes = (FileUploadParser,)
def put(self, request, property_id=None, format=None):
serializer = self.serializer_class(data=request.data, partial=True)
if not serializer.is_valid():
return Response(serializer.errors, status= status.HTTP_400_BAD_REQUEST)
else:
serializer.save()
return Response(serializer.data, status=status.HTTP_200_OK)
url(r'^upload/images/(?P<property_id>[0-9]*)/$', views.PropertyGallery.as_view(), name='property-gallery'),

If you remove the line,
parser_classes = (FileUploadParser,)
the fields of the serializer will be displayed.
Since you wrote a view that updates existing objects, you may need to throw an exception if the object does not exist with a specific identifier. To do this, you can use the quick access function get_object_or_404()
.
from django.shortcuts import get_object_or_404
def put(self, request, property_id=None, format=None):
_property = get_object_or_404(Property, id=property_id)
serializer = self.serializer_class(data=request.data, partial=True)
if not serializer.is_valid():
return Response(serializer.errors, status= status.HTTP_400_BAD_REQUEST)
else:
serializer.save(property=_property)
return Response(serializer.data, status=status.HTTP_200_OK)

I am posting a solution to link multiple images to property. This is working code, but the code requires much more attention. Please feel free to make the following code better.
class GallerySerializer(serializers.ModelSerializer):
class Meta:
model = Gallery
fields=('id', 'caption', 'image', )
def perform_create(self, serializer):
print ('serializer', serializer)
serializer.save(property_instance_id=serializer.validated_data['property_id']) #property_instance_id is because i have changed the name property to property_instance in Gallery model as property is the reserved keyword
class PropertyGallery(APIView):
serializer_class = GallerySerializer
parser_classes = (FormParser, MultiPartParser, )
def put(self, request, property_id=None, format=None):
serializer = self.serializer_class(data=request.data, partial=True)
if not serializer.is_valid():
return Response(serializer.errors, status= status.HTTP_400_BAD_REQUEST)
else:
serializer.save(property_instance_id=property_id)
return Response(serializer.data, status= status.HTTP_200_OK)
