当我保存到 xls 时，我正在尝试自定义格式：

  • 我需要帮助自定义=“日期”+“ejecutive selected”+“.xls”

但不工作

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 = ? ", search.to_i  ] )
    else
      find(:all)
    end
   end
end

class Ejecutive < ActiveRecord::Base
  has_many :policies
end

这是我的控制器。在这里，我输入了我正在尝试使用日期 + ejecutive selected + .xls 自定义的格式

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

      respond_to do |format|
        format.html
         format.xls { send_data render_to_string(:partial=>"report_by_ejecutive_xls"), :filename => "#{Date.today}#{@ejecutives.name}.xls" }
      end  
end

这是我的看法

<% form_tag :controller=>"policy_management/policy",:action =>"generate_print_ejecutive_comercial", :method => 'get' do %>
    <%= select_tag "search", 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 %>

 <%= link_to "Export", :controller=>"policy_management/policy",:action=>"generate_print_ejecutive_comercial" ,:format=>"xls",:search => params[:search],:page => params[:page] %>

这是我要导出到 excel 的部分观点

************report_by_ejecutive_xls.************** 
<% @results.each do |policy| %>
    <%= policy.num_policy%>
       <% if !policy.ejecutive.blank? %>
    <%= policy.ejecutive.name %><%= policy.ejecutive.lastname1 %><%= policy.ejecutive.lastname2 %>
      <% end %>
<% end %>

我试过了，但只保存了第一个 ejecutive，我只想在我的视图中选择 ejecutive

      format.xls { send_data render_to_string(:partial=>"report_by_ejecutive_xls"), :filename => "#{Date.today}#{@ejecutives.first.name}.xls" }

请问有人可以帮我解决这个问题吗？

所选的喷射对象在控制器中不可用。因此需要进行一些重构以在控制器中获取选定的喷射器，然后使用它来获取策略

class PolicyManagement::PolicyController < ApplicationController
    def generate_print_ejecutive_comercial
       @ejecutives = Ejecutive.find(:all)

       #changed to find selected ejecutive here
       @selected_ejecutive = Ejecutive.find_by_id(params[:search])  if params[:search]

       # changed the search method for policies
       @search = @selected_ejecutive.try(:policies) || Policies.scoped

       @policies = @search.paginate( :page => params[:page], :per_page =>10)

       # changed this line as results is same as @search
       @results = @search

       @ejecutive_name = @selected_ejecutive.try(:name) || "All"

      respond_to do |format|
         format.html

         #changed the name here
         format.xls { send_data render_to_string(:partial=>"report_by_ejecutive_xls"), :filename => "#{Date.today}#{@ejecutive_name}.xls" } 
      end  
end

现在不需要这种search方法。
