如何将值从视图传递到另一个视图以填充 rails 3 中的另一个表单？
我是rails新手，我对如何实现这一点有点困惑，这是我的场景：
我生成了一个客户和一个销售脚手架，然后在客户索引视图中放置了一个搜索文本字段，用于搜索客户并将其呈现在其下方。每个客户都有一个名为“销售”的按钮，单击它时应将您重定向到 new_sales_path 并使用客户的值自动填写表单的某些字段，例如：姓名、地址、ID、电话号码等...
所以我想要做的是：我想在单击按钮 Sale 时传递客户的信息，然后污染 new_sales 表单。
所以我在索引客户端视图中有这个代码：
<%= form_tag clientes_path, :method => 'get', :id => "clientes_search", :class => "form-search" do %>
<p>
<%= text_field_tag :search, params[:search], :class => "input-medium search-query" %>
<%= submit_tag "Search", :name => nil, :class => "btn" %>
<% @clients.each do |client| %>
<tr>
<td><%= client.id %></td>
<td><%= client.email %></td>
...
...
<%= link_to t('.edit', :default => t("helpers.links.edit")),
edit_client_path(client), :class => 'btn btn-mini' %>
<%= link_to "Sale", new_sale_path, :action => 'sale_button', :id => 'sale_button', :class => 'btn btn-mini' %>
<% end %>
</tr>
<% end %>
在我的应用程序助手中，我有：
def sale_button
@sale_button = client
end
在我的客户和销售控制员中，我有这样一行：
helper_method :sale_button
在我的新销售视图中，我有
<div id='sales'>
<%= simple_form_for @sale, :html => { :class => 'form-horizontal' } do |f| %>
<%= f.input :client, :label => "Client ID", :required => true, :as => :string, :input_html => { :value => @sale_button.id } %>
...
...
<% end %>
我不知道我是否以正确的方式做这件事，或者我是否缺少某些东西，欢迎提供任何帮助或意见。
我正在使用 Rails 3.2 顺便说一句
