Flask Restful accept a list in a post request

I am using Flask Restful for my server API and am posting to the server a dictionary where one of the values is a list of dictionary's.

parser.add_argument('products_in_basket', type=list)
def post(self, user_id):
   args = parser.parse_args()
   print request.data
   print args['my_list']

The problem I have is args['my_list'] is only returning the first element of the list. Whereas I can see all list from request.data.

This is request.data

{"address_id":1,"my_list":[{"size":12,"colour":"red","id":34219,"quantity":1},{"size":10,"colour":"red","id":12219,"quantity":2},{"size":8,"colour":"red","id":5214,"quantity":3}],"payment_card_id":1}

This is args['my_list']

[u'colour', u'quantity', u'id', u'size']

Where am I going wrong?

Solution

  • What are your parser add_argument options? Is products_in_basket an actual key to the data that is requested? Or are you trying to provide an arbitrary name and/or rename the dict?

    Take a look at Multiple Values & Lists from the Request Parsing documentation.

    You may want to be doing something like this instead...

    parser = reqparse.RequestParser()
parser.add_argument('my_list', action='append')
