":validate => true" vs. "validate => :true"

It may sound obvious, but "form_for :validate => true" is different from "form_for :validate => :true" (note the symbol instead of true).

This is because when you pass a symbol to :validate it will assign the script to content_for so you can render the script tag elsewhere. (See https://github.com/bcardarella/client_side_validations/issues/98)

If you accidentally use :true instead of true your client side validations will not work, with the following error displayed in your browser's js error console.

"settings is undefined"
