Django - Get query parameter list

Don't send it in that format in the first place. The standard way of sending multiple values for a single HTML is to send the parameter multiple times:

http://127.0.0.1:8000/auction/?status=omn&status=aad

which will correctly give you ['omn','aad'] when you use request.GET.getlist('status').

request.GET['status'] would return you ['omn', 'aad'].

Expanding on @DanielRoseman's answer.

The correct way would be to pass each variable as described: http://127.0.0.1:8000/auction/?status=omn&status=aad.

However, if you're using modern Javascript frameworks (Vue, Angular, React) there's a good chance you're passing params as an object (e.g., if you're working with axios, VueResource, etc). So, this is the work around:

Front-end:

let params = {
   status: ['omn', 'aad',]
}

return new Promise((resolve, reject) => {
  axios.get(`/auction/`, { params: params }, }).then(response => {
      resolve(response.data);
  }).catch(error => {
      resolve(error.response);
  });
});

This will then dispatch to Django as the following URL:

[05/Aug/2019 10:04:42] "GET /auction/?status[]=omn&status[]=aad HTTP/1.1" 200 2418

Which can then be picked up in the corresponding view as:

# Before constructing **parameters, it may neccessary to filter out any supurfluous key, value pair that do not correspond to model attributes:
parameters['status__in'] = request.GET.getlist('status[]')

# Using parameters constructed above, filter the Auctions for given status:
auctions = Auction.objects.filter(is_active=True)

auctions = auctions.filter(**parameters)
