Simply put, I am trying to test a view name, captured from a URL parameter, within one of my view functions to see if it is valid. If not, to redirect to another page.
For example, take this url…
www.site.com/users/?ref=view_name
Then in my view
ref = request.GET.get('ref', None)
return redirect(ref) if ref else redirect('users')
The problem is, of course, that if a user alters the ref parameter, it will kick back a 404. I was hoping to be able to test if ref=home is a valid view and return it, if not then redirect to another view.
I have been messing with Django’s resolve and reverse but I am not getting the results I was looking for.
I also tried to use a try/finally in all sorts of ways mixed in with resolve and reverse. Yeah, dumb…I know.
try:
if ref:
return redirect(resolve(ref))
finally:
return redirect('user')
I have searched for almost two hours to try to fund a succinct way to do this.
Any help would be appreciated!
>Solution :
The problem is that you are passing a view name to resolve() which requires a URL path. To protect against 404, you need to first reverse() the view name to get a path. Then you can use that path with resolve() to check if the path exists.
