Django url path regex: capturing multiple values from url

Question

How do I capture multiple values from a URL in Django?

Conditions: I would like to capture ids from a URL. The ids vary in length (consist of numbers only), and there can be multiple ids in the URL. Check out the following two examples:

http://127.0.0.1:8000/library/check?id=53&id=1234

http://127.0.0.1:8000/library/check?id=4654789&id=54777&id=44

The solution may include regex.

urlpatterns = [
    path("", view=my_view),
    path("<solution_comes_here>", view=check_view, name="check_view"),
]

P.S. all solutions I found on this platform and Django documentation only explain cases for capturing single values from the URL

Answer 1

You use:

urlpatterns = [
    path('', view=my_view),
    path('check/', view=check_view, name='check_view'),
]

Indeed, the querystring is not part of the path. This can be determined with request.GET. So you can obtain the ids with:

def check_view(request):
    ids = request.GET.getlist('id')  # ['3654789', '54777', '44']
    # …

There is however no guarantee that the ids will only be numerical, so you will need to validate that in the view itself.

request.GET is a Querydict. It has more methods than an ordinary dict.

What you want for this is request.GET.getlist("id") which will return a list of id values. .get("id") will return only the last of them.
