我正在尝试使用 2 个表按关系创建搜索，其中：

1）我在我的视图“政策”中使用“select_tag”选择我所有的ejecutives。

2）从我的表“Ejecutives”中选择一个 ejecutive 后，我想要我这样选择的 ejecutive 的所有政策。

select* from policies where ejecutive_id = 1
select* from policies where ejecutive_id = 2
select* from policies where ejecutive_id = "the ejecutive that i selected"

我的桌子

 TABLE EJECUTIVES
       |id|  |name| |lastname1|
 TABLE POLICIES
       |id|  |num_police|  |ejecutive_id|

我的模型

class Policy < ActiveRecord::Base
   unloadable
   belongs_to :ejecutive
   has_many :policy

   def self.search(search)
    if search
      find(:all, :conditions => ["ejecutive_id LIKE ? ", "#{search}"  ] )
    else
      find(:all)
    end
   end
end

class Ejecutive < ActiveRecord::Base
  has_many :policies
end

这是我的控制器

class PolicyManagement::PolicyController < ApplicationController
    def generate_print_ejecutive_comercial
      @ejecutives = Ejecutive.find(:all)
      @policies = Policy.search(params[:search]).paginate(:page => params[:page], :per_page => 10)
    end
end

这是我的看法

<% form_tag :controller=>"policy_management/policy",:action =>"generate_print_ejecutive_comercial", :method => 'get' do %>
    <%= select_tag "Ejecutives", options_for_select(@ejecutives.collect {|t| [t.name.to_s+" "+t.lastname1.to_s,t.id]}) %>
    <%= submit_tag "Search", :name => nil %>
<% end %>

 Results
     <% @policies.each do |policy| %>
     <p> <%= policy.num_policy%> </p>
     <p> <%= policy.ejecutive.name %> </p>
     <p> <%= policy.ejecutive.last_name %> </p>
     <% end %>
     <%= will_paginate @policies %>

我试过这个

 %= select_tag "Ejecutives", options_for_select(@ejecutives.collect {|t| [t.name.to_s+" "+t.lastname1.to_s,t.id]}),params[:search] %>

有人知道这个问题吗？我真的很感激帮助。

将标签名称更改为search.

<%= select_tag "search", options_for_select(@ejecutives.collect {|t| [t.name.to_s+" "+t.lastname1.to_s,t.id]}) %>

也改变搜索方法

  find(:all, :conditions => ["ejecutive_id = ? ", search.to_i  ] )
