I need my django application connect two different URLs to the same view. When I use regular expression, the result is different from what I expect:
from django.http import HttpResponse
from django.urls import re_path
def readme(request):
return HttpResponse('My test', content_type='text/plain')
urlpatterns = [
re_path(r'^(readme|help)$', readme),
]
I should render both
to the same view. But I receive the following error when entering the URL in my browser:
Exception Value: readme() takes 1 positional argument but 2 were given
Exception Location: /home/ar/.local/lib/python3.8/site-packages/django/core/handlers/base.py, line 197, in _get_response
191 if response is None:
192 wrapped_callback = self.make_view_atomic(callback)
193 # If it is an asynchronous view, run it in a subthread.
194 if asyncio.iscoroutinefunction(wrapped_callback):
195 wrapped_callback = async_to_sync(wrapped_callback)
196 try:
197 response = wrapped_callback(request, *callback_args, **callback_kwargs)
198 except Exception as e:
199 response = self.process_exception_by_middleware(e, request)
200 if response is None:
201 raise
202
203 # Complain if the view returned None (a common error).
As error message says, the view need 2 arguments, but you have declared one. That another argument will be your readme or help.
So for solving it, you can use *args:
def readme(request, *args, **kwargs):
return HttpResponse('My test', content_type='text/plain')
Or if you want the readme or help in your view, you can have it as just argument:
def readme(request, selected_url):
return HttpResponse('My test', content_type='text/plain')
