parameter passing in django - django

Question

I am trying to use REST API in django for retrieve some data in json format.
When i hit this url:
http://192.168.2.87:8000/locker/123/
It gives me output like this (from Database)
{"id": 1, "locker_id": 123, "locker_user_name": "taimur"}
But if i want to get the output by passing the parameters like this
http://192.168.2.87:8000/locker/?locker_id=123&locker_user_name=taimur&id=1
views.py
from postman, How can i do this??
from django.shortcuts import render, HttpResponse, get_object_or_404
from django.http import JsonResponse
from .models import Locker
from .serializers import LockerSerializer
from rest_framework.response import Response
from rest_framework import status
from rest_framework.views import APIView
def locker_data_response(request, locker_id):
if request.method == 'GET':
locker_information = get_object_or_404(Locker, locker_id = locker_id)
print(locker_information)
locker_information_serialize = LockerSerializer(locker_information)
print(locker_information_serialize)
return JsonResponse(locker_information_serialize.data)
urls.py
from django.urls import path, re_path
from . import views
urlpatterns = [
re_path('(?P<locker_id>[0-9]+)/$', views.locker_data_response, name='locker_data_response'),
]

Answer 1

You get them from the request object:
def locker_data_response(request):
if request.method == 'GET':
locker_id = request.data.get('locker_id') # this will return None if not found
locker_user_name = request.data.get('locker_user_name')
locker_information = get_object_or_404(Locker, locker_id=locker_id)
print(locker_information)
locker_information_serialize = LockerSerializer(locker_information)
print(locker_information_serialize)
return JsonResponse(locker_information_serialize.data)
And the url will change to:
locker/$
[EDIT: Sorry, if you are using drf you should use data rather than GET]
[EDIT 2: If you want to use it like this, you will also need to change the url and signature of the view]
[EDIT 3: Added the code in the correct place in view]

Answer 2

If your url is something like domain/search/?q=haha, Then you would use request.GET.get('q', '').
q is the parameter you want, And '' is the default value if q isn't found.
If you are instead just configuring your URLconf, Then your captures from the regex are passed to the function as arguments (or named arguments).
Such as:
(r'^user/(?P<username>\w{0,50})/$', views.profile_page,),
Then in your views.py you would have
def profile_page(request, username):
# Rest of the method
