[Fixed]-Django.utils.datastructures.MultiValueDictKeyError with form post data

Your POST data is really weird but for the sake of correctness, you should do:

first_name = post_data["user_data[first_name]"]
name_last = post_data["user_data[name_last]"]

Because the string user_data[first_name] is the key for the dict not just string user_data.

Edit:

If you want to convert user data into dict, you should loop on request.POST and check for keys that contains user_data keyword:

user_data = {}
for key, value in request.POST.iteritems():
    if 'user_data' in key:
        field = key.split('[')[1].replace(']', '')
        user_data[key] = value

# convert into json
json_user_data = json.dumps(user_data)
