Solution For "rewrite" error

If you get this error, and the error message is pointing you to a “link_to” call or something similar, then you may be using an instance variable that’s called ‘@url’ too.

I finally discovered that, in my case, I was using ‘@url’ in the controller for the view where I was making the ‘link_to’ call.

Long story short, if you see this error, comb through your code (models, controllers and views) for any variables that are called ‘@url’ and change them.


Reason:

We should not use "url" word as controller name,model name,action name,attribute name ..
Apparently you can’t use “Class” as a class in Java either.

Yep, same as ‘private’, ‘public’, etc. With the slight difference that these are keywords at the language as oposed to framework level.


Solution:
Then simply replace url word with other..
