how to get specific list with all data from a queryset django?

Question

on server sends this data:

Object { categoryes: Array[2], brands: Array[2], discount_list: "all", category_slug: "accessories", category_of_relationsheep: "m" }

if i print request.POST in server side i got this:

<QueryDict: {'categoryes[]': ['Accessories', 'Bands'], 'brands[]': ['Nike', 'HBO'], 'discount_list': ['all'], 'csrfmiddlewaretoken': ['S7MXVEdQLd6u0fr4FugEwlupa45oChmw3TeItB4BEUHUHSsxrmVRuAcAhFxYQfpk'], 'category_slug': ['accessories'], 'category_of_relationsheep': ['m']}>

hot i can get a list for example "categoryes[]" (but why it called like this with brackets?)

ok if i do like this: print(request.POST.get("categoryes[]")) it will give the only last object,

how to get full list? specific like cotegoryes? if make like

for keys, values in request.POST.items():
    print(values)

it print me all values in this dict, but i don't know from where this values? if i make this:

for keys, values in request.POST.items():
        if 'categoryes[]' == keys:
            print(values)

it give the same only one object related to categoryes but in this list more than 1 object

Try using getlist

request.POST.getlist('categoryes[]')

When accessing request.GET and request.POST, you don't get a regular dictionary, you get a QueryDict object. When accessed as a dictionary, it returns the last value for a key. If you want the full list, use the getlist method, for instance:

request.POST.getlist("somekey")

Returns a list of the data with the requested key.
