Why? Becouse i can write BaseController method like this:
def check_params!(path, exception = "Not enough params")
raise exception unless params.deep_symbolize_keys.path_exists?(path)
end
And use it like this in needed controller action: check_params!({:user => [:email]}, "No email")
instead of raise "No email" unless params[:user] && params[:user][:email]
What do you think about this? Is it good idea?/related to Ruby On Rails, i write some RESTful api app and every time will check input params.
