[Fixed]-How to send nested form-data using postman?

Try this:

cars[0][car_img_1]:car_img_file1
cars[1][car_img_2]:car_img_file2

You can insert it in “bulk-edit” mode.

I found this answer from this problem. Edited as per your code.

Convert your Image Fields to base64Image and send it through the JSON data.

All you need to do is:

1. go to https://www.base64-image.de/ and convert the image to base64 format. Copy the encoded result.
2. Install django-extra-fields package in your project from here
3. In your serializer_class, import and change the image field to Base64ImageField:

serializers.py

...
from drf_extra_fields.fields import Base64ImageField
...
 

4. Now, go to your postman and send the JSON data like the following. Remember to send that encoded image in your image field in JSON.

{
    "name":"John",
    "age":30,
    "cars": 
    {
        "car_img_1":"<base64 encoded image>",
        "car_img_2":"<base64 encoded image>",
        "car_img_3":"<base64 encoded image>"
    }
 }

You should try in this way (Hint: Watch carefully form-data key names):
