I am designing the endpoint that receive single POST with multiple images.
Here is my simple endpoint by Django REST
models.py
class CaseImage(models.Model):
image = models.ImageField(upload_to='case_images')
issue = models.ForeignKey(CaseIssue, related_name='images', related_query_name='images', on_delete=models.CASCADE)
serializers.py
class MyImageSerializer(serializers.ModelSerializer):
class Meta:
model = CaseImage
fields = [
'id',
'image',
]
class NewCaseIssueSerializer(serializers.ModelSerializer):
images = MyImageSerializer(many=True)
class Meta:
model = CaseIssue
fields = [
'id',
'machine',
'symptom',
'images',
'activities',
]
def create(self, validated_data):
from pprint import pprint
import ipdb; ipdb.set_trace()
images = validated_data.pop('images')
instance = super().create(validated_data)
tmp = []
for image in images:
tmp.append(CaseImage(issue=instance, image=image))
CaseImage.objects.bulk_create(tmp)
return instance
I am imitating this answer
My break point found empty list of images
> /Users/sarit/Code/mp_resource/mp_resource/case_issues/api/serializers.py(115)create()
114 import ipdb; ipdb.set_trace()
--> 115 images = validated_data.pop('images')
116 instance = super().create(validated_data)
ipdb> validated_data
{'machine': <Machine: eNYfySyXcDgplaeDXKbxxwmEYbFawyOOgDOhKaUTtBNExPxVbC>, 'symptom': 'First symptom', 'images': []}
Questions:
1. Is it practical to POST multiple images in single shot?
2. If it is practical. How to do that in Postman application?
