Re: request.POST.getlist('xxx') only has one value in ajax request for many2many

Yeah - I am looping.  I just get one iteration which is the last item even though the request body has the same key repeated.

For example, this code only prints one item, whereas for a different form elsewhere, it would iterate through all the identical keys:

       print(self.request.__dict__)

      for pool in self.request.POST.getlist('pool_list'):

      print(f"form pool_list item: {pool}")

The main difference to when it works is that this form is submitted via ajax; and uses UpdateView.

Essentially, this is expected behavior, and previous comment is correct.  Need to loop through the items in the list

You might want to loop through the list 

Example:

Lists = request.getlist('item')

For list in Lists:

Hi,

Using Django 3.2 and Py 3.9

I have an ajax request which submits multiple values for a field to an UpdateView.

In the request dict body I see both values (in this case, for the pool_list column):

'_body': b"csrfmiddlewaretoken=z...h&...&key=...&expiry_datetime=&overflow=555&pool_list=507&pool_list=499&...

Later in the request dict, I only see one of the values in the _post:

'_post': .... 'pool_list': ['499'],

This means that in request.POST.getlist('pool_list'), I'm only getting one result in the list object.

Any idea why it's only the last value being populated in the getlist?
