javascript – 确定rails3 jquery autocomplete插件的结果

@H_772_1@我正在使用 https://github.com/crowdint/rails3-jquery-autocomplete,它似乎正在工作.唯一的问题是让我说我​​有一个字段在所有帖子标题上执行自动完成,但我希望它只显示用户创建的帖子的标题.

有没有办法做这样的事情？即一个find_by还是什么？

谢谢！

它在文档中说：

If you want to display a different version of what you're looking for,you can use the :display_value option.

This options receives a method name as the parameter,and that method will be called on the instance when displaying the results.

class Brand < ActiveRecord::Base
  def funky_method
    "#{self.namE}.camelize"
  end
end


class ProductsController < Admin::BaseController
  autocomplete :brand,:name,:display_value => :funky_method
end
In the example above,you will search by name,but the autocomplete list will display the result of funky_method

我觉得这可以用来做我想要完成的事情,但我不知道从哪里开始？

class UsersController < ApplicationController
    autocomplete :user,:email,:full => true

    def index
        @users = User.all
    end

    def get_items(parameters)
        [User.last]
    end
