How to send nested form-data using postman?

Question

Assume I have some data as below,

{
    "name":"John",
    "age":30,
    "cars": 
    {
        "car_img_1":"car_img_file1",
        "car_img_2":"car_img_file2",
        "car_img_3":"car_img_file3"
    }
 }

How can I send it using POSTMAN with form-data?

NOTES
1. car_img_fileX will be the file(.jpg,.png etc types)
2. What I'd tried -->> POSTMAN Screenshot.
3. Local server builted with Django framework


Current Output
Receiving 5 different items/data instaed of Nested data--> see this Pycharm Debugger Output

Answer 1

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.
