django.utils.datastructures.MultiValueDictKeyError with form post data

django.utils.datastructures.MultiValueDictKeyError: "'user_data'"

Is what i get when trying to access user_data from the request.POST

post_data = dict(request.POST)
print(post_items)

returns

{'user_data[first_name]': ['Jamie'], 'user_data[name_last]': ['Lannister'], 'campus': ['McHale Hall'], 'user_data[twitter]': ['@jamielan']}

So if I try to get just the user_data, I try this (doesn't work)

post_data = dict(request.POST)
user_data = post_data['user_data']

I just want to get all instances of user_data in this dict and store as json. How can I do that?

Expected out put would be something like

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)
