[Answered ]-Why is Django's client.post nesting arg values in lists?

I don’t think this happens when my frontend posts data.

The same key can be associated multiple times to a value, for example when you use a checkbox with:

<input type="checkbox" name="foo" value="bar">
<input type="checkbox" name="foo" value="qux">

If you check both checkboxes, it will add foo=bar&foo=qux to the request body, so the same key (foo) is associated to both bar and qux.

If you use request.POST['foo'] it will return the value of the last record, so 'qux'. You can also use request.POST.getlist('foo') it will return all values for that key in a list, so ['bar', 'qux'].
