I am trying to POST data to my API. I have a model with an image field where:
image = models.ImageField()
I have an image on my local box, which I am trying to send. Am I sending it correctly?
{
"id": "3",
"uid":"273a0d69",
"uuid": "90",
"image": "@/home/user/Downloads/tt.jpeg"
}

The answer is
That's not how you send file on postman. What you did is sending a string which is the path of your image, nothing more.
What you should do is;
- After setting request method to POST, click to the 'body' tab.
- Select form-data. At first line, you'll see text boxes named key and value. Write 'image' to the key. You'll see value type which is set to 'text' as default. Make it File and upload your file.
- Then select 'raw' and paste your json file. Also just next to the binary choice, You'll see 'Text' is clicked. Make it JSON.
You're ready to go.
In your Django view,
from rest_framework.views import APIView
from rest_framework.parsers import MultiPartParser
from rest_framework.decorators import parser_classes
@parser_classes((MultiPartParser, ))
class UploadFileAndJson(APIView):
def post(self, request, format=None):
thumbnail = request.FILES["file"]
info = json.loads(request.data['info'])
...
return HttpResponse()
Follow the below steps:
- No need to give any type of header.
Select body > form-data and do same as shown in the image.
Now in your Django view.py
def post(self, request, *args, **kwargs): image = request.FILES["image"] data = json.loads(request.data['data']) ... return Response(...)
- You can access all the keys (id, uid etc..) from the data variable.
The accepted answer works if you set the JSON as a key/value pair in the form-data panel (See the image hereunder)
Nevertheless, I am wondering if it is a very clean way to design an API. If it is mandatory for you to upload both image and JSON in a single call maybe it is ok but if you could separate the routes (one for image uploading, the other for JSON body with a proper content-type header), it seems better.
Now you can hover the key input and select "file", which will give you a file selector in the value column:
