POST variable name array is being is treated as a string

Using Django Forms & APIs
1

I have this in my front-end (using AlpineJS to go through a loop) :

x-model="rule.protocol"
:name="'protocol[' + rule.pk + ']'"
:value="rule.protocol"

So the print(request.POST) is like this :

<QueryDict: {'csrfmiddlewaretoken': ['xxx'], 'rules[]': ['18580', '18581', '18582', '18583'],
'type[18580]': ['SSH'], 'protocol[18580]': ['TCP'], 'port_range[18580]': ['343434'],
'ip_range[18580]': ['Custom'], 'source_destination[18580]': ['172.16.16.0/24'],
...

I want request.POST['type[18580]'] as request.POST['type'][18580] and not as a string (‘type[18580]’)

The post data you are retrieving is form data?

Yes - its form data and I am not using formset.

okay so if your using form you can do something like this

# forms
CHOICES = (
    (1, "TEST 1"),
    (2, "TEST 2"),
    (3, "TEST 3"),
    (4, "TEST 4"),
)

class TestForm(forms.Form):
    array = forms.MultipleChoiceField(choices=CHOICES)


# view
def test(request, id):
    data = {}
    if id == "add":
        data['obj'] = None
        data['form'] = TestForm()
        if request.method == "POST":
            # request.POST.getlist("array") by using this you can get list of data
            print(request.POST.getlist("array"))
            data['form'] = TestForm(request.POST)

    if request.method == "POST":
        if data['form'].is_valid():
            return redirect('.')

    return render(request, html_path, data)

Let me simplify this :

I have a <form> which has 3 input fields :

<input type="text" name="foo[10]" value="a" />
<input type="text" name="foo[22]" value="b" />
<input type="text" name="foo[35]" value="c" />

How do I access it as request.POST['foo'][22] instead of request.POST['foo[22]']

Django does not offer such parsing of POST data out of the box.

You will have to do parsing yourself. You can check what DRF does for that: https://github.com/encode/django-rest-framework/blob/master/rest_framework/utils/html.py#L15

I guess I’ll revert to :

<input type="text" name="age" value="a" />
<input type="text" name="age" value="b" />
<input type="text" name="age" value="c" />

and ages= request.POST.getlist('age')
