How to send multiple input field values with same name?

问题

I have m2m field, lets say it have name 'relations', so i want to allow user to send as many relations as he wants. I add new input to html with javascript with same name, like so

<input type='text' name='relations' value='a' />
<input type='text' name='relations' value='b' />

in cleaned_data i receive only value of second input ('b'). How to receive both?

回答1:

I don't know how to do that with Forms, but if you want to grab the values in the raw way, here's how I'd do:

relations = request.POST.getlist('relations')

回答2:

You don't need to grab all the raw values, you can just get the specific data by using element name like this:

relations = request.form.getlist('relations')

That will return a list of values in the relations input.

回答3:

this generate a list, you can manipulate in for

request.POST.getlist('relations')
