Posting nested params with curl -F flag - php

Question

I’m trying to post an image and a few nested parameters to an api using django rest framework. I’m trying to set up a curl with -F flags as discussed here with nested params as discussed here:
curl -X POST -S -H 'Accept: application/json' -F "customer[name]=foo&customer[email]=foo#bar.com&customer[zipcode]=1076AL&customer[city]=Amsterdam&customer[address]=foobar" -F "photo=#/Users/vincentvanleeuwen/Desktop/tmp/accord.jpg;type=image/jpg" http://localhost:8000/api/orders/
But I get the following response:
{"customer":{"city":["This field is required."],"email":["This field is required."],"zipcode":["This field is required."],"name":["This field is required."]}}
There seems to be something wrong with my nesting under the -F flag, as the nested variables work if I post it like this:
curl -X POST -S -H "Content-Type: application/json" -d '{"customer":{"name":"Adriaan","email":"adriaan#adriaan.com","zipcode":"1901ZP","address":"caravan","city":"Verweggistan"}}' http://localhost:8000/api/orders/
Any ideas what I’m doing wrong? Any help would be much appreciated!

Try separate -F flags for each parameter? From the curl manual:
Emulate a fill-in form with -F. Let's say you fill in three fields
in a form. One field is a file name which to post, one field is your
name and one field is a file description. We want to post the file
we have written named "cooltext.txt". To let curl do the posting of
this data instead of your favourite browser, you have to read the
HTML source of the form page and find the names of the input fields.
In our example, the input field names are 'file', 'yourname' and
'filedescription'.
curl -F "file=#cooltext.txt" -F "yourname=Daniel" \
-F "filedescription=Cool text file with cool text inside" \
