params.require(:person).permit(:name, :password,:adress) ,用来过滤时,为什么过滤后的结果还是没有的过滤前的值 过滤前:Parameters: {"utf8"=>"���", "authenticity_token"=>"61rMuV5wQEk4Wq15T0NAGNpKlo0GXJmvwP9jNZpJQMg=", "person"=>{"name"=>"jyw", "password"=>"[FILTERED]", "adress"=>"[email protected]"}, "commit"=>"������"} 过滤后: {"utf8"=>"���", "authenticity_token"=>"61rMuV5wQEk4Wq15T0NAGNpKlo0GXJmvwP9jNZpJQMg=", "person"=>{"name"=>"jyw", "password"=>"123456", "adress"=>"[email protected]"}, "commit"=>"������", "controller"=>"index", "action"=>"create"} 为什么会这样,求大神解释。rails 版本是 4.1.2,ruby 是 19.3
