local variable error when trying multiform in one view

Question

I was searching the internet for a solution for using two forms in one view, and found this Proper way to handle multiple forms on one page in Django.

But I get local variable 'loginform' referenced before assignment error when trying to post any of the forms.

please let me know if the method I'm using is wrong.

Thanks

Please show the full traceback. Where do you get that error? What action are you performing when you do? — Daniel Roseman, Nov 04 '15 at 09:05
I think you got this error because neither "Login" nor "Register" is present in request.POST. — Guillaume Pannatier, Nov 04 '15 at 09:20

You're not sending either Login or Register in your post data, so neither of the conditions will ever be true on post and the variables remain undefined.

You have given your submit buttons values, but not names, so they cannot be included in the post data. Do this:

<input type="submit" name="Login" value="Login"/>
...
<input type="submit" name="Register" value="Register"/>
