这是我在 Ruby on Rails 3 项目中的模型:
class Faye < ActiveRecord::Base
def faye_chatroom_token_id
a = Faye.find_by_sql("SELECT userid FROM chat WHERE id = #{current_profile.id}")
Digest::MD5.hexdigest(a.first)
end
end
我需要在 javascript 中使用它:
function broadcast(){
var channel = **Hier I will call the model method**;
$.ajax({
type: 'POST',
url: "http://localhost:9292/faye",
data: 'message={"channel":"/'+channel+'/chatroom", "data":"1"}',
dataType: "json",
xhrFields: {withCredentials: true},
crossDomain: true,
});
}
请帮我!
