Django pass CommaSeparated values to GET paramater

Question

We know that django has CommaSeperated model field. But how can we pass commaSeparated string to Django GET parameter.

Whenever i try to pass something like below as GET parameter:

1,2,3,4

I receive using below code in django view

request.GET.get('productids','')

It ends up like below in django view.

'1,2,3,4' 

Its ends up adding quotes around the array.

Please any Django experts help me with this issue.

Answer 1

You can use getlist

param_list = request.GET.getlist('productids')

If you're passing it as a single parameter then you can construct it

param_list = [int(x) for x in request.GET.get('productids', '').split(',')]

Answer 2

Django converts GET and POST params to string (or unicode). That means, if you're sending a list (array) as a GET param, you'll end up getting a string at the backend.

However, you can convert the string back to array. Maybe like this:

product_ids = request.GET.get('productids', '')
ids_array = list(product_ids.replace(',', '')) # remove comma, and make list

The ids_array would look like this - ['1', '2', '3'].

Update:

One thing worth noting is the ids in ids_array are strings, not integers (thanks to Alasdair who pointed this out in the comments below). If you need integers, see the answer by Sayse.
