How to upload multiple images in django rest framework - django

Question

I want to upload multiple images using image model not like a nested serializer
Here is my serializer
class ProjectImageSerializer(ModelSerializer):
class Meta:
model = ProjectImage
fields = (
'id',
'file',
'project',
)
This is the model
class ProjectImage(models.Model):
file = models.ImageField(
upload_to='apps/projects/ProjectImage/file/',
)
user = models.ForeignKey(
'users.User',
on_delete=models.CASCADE,
related_name='project_image_set',
)
project = models.ForeignKey(
'Project',
on_delete=models.CASCADE,
related_name='image_set',
)
created = CreatedField()
last_modified = LastModifiedField()
def __str__(self):
return basename(self.file.name)
and here is Views.py
class ProjectImageViewSet(viewsets.ModelViewSet):
parser_classes = [
MultiPartParser,
]
queryset = ProjectImage.objects.all()
serializer_class = ProjectImageSerializer
can anyone help me when I try with postman its selecting multiple images but posting only one

Answer 1

class ProjectImageSerializer(ModelSerializer):
class Meta:
model = ProjectImage
fields = (
'id',
'file',
'project',
)
read_only_fields = ['id']
extra_kwargs = {'file': {'required': 'True'}}
Try above code

You can't use this serializer for uploading multiple images. You should define another serializer which accepts a list of files in one of the fields. Something like this:
def UploadSerializer(serializers.Serializer):
images = serializers.ListField(child=serializers.ImageField())
And then implement your logic to create ProjectImage instances in the create method.
