Getting error "exceeded available parameter key space"?

Question

In my rails application, after form post, getting error exceeded available parameter key space. there are too many form fields inside form. Is that reason for error? Any views?

Answer 1

If you really need it badly try increasing the key_space_limit

Rack::Utils.key_space_limit = 262144 

But this can be dangerous as per this "A higher exposure to POST parsing DOS attacks."
