幫助Rails項目快速實現搜索

本軟件可以幫助Rails項目快速實現搜索／過濾頁面。具體使用，請參照軟件主頁里的說明。

1. Include gem into Gemfile

   gem 'rails-simple-search'

2. Code in model (app/model/search.rb):

   class Search < RailsSimpleSearch::Base
   end

3. Code in controller:

   @search = Search.new(User, params[:search])
   @search.order = 'email'  # optional
   @users = @search.run

4. Code in views:

   <% form_for @search, url => "/xxxxxx" do |f| %>
   
     <%=f.label :email %>
     <%=f.text_field :email %>
   
     <%=f.label :state%>
     <%=f.select "address.state_id", [['AL', 1], ...] %>  <!-- address is an association of model User -->
   
     <%=f.label :post%>
     <%=f.text_field "posts.comments.author" %>           <!-- the associations could go even deeper, isn't it POWERFUL? -->
   
     <%=f.submit %>
   <% end %>
   
   <% @users.each do |user| %>
    <%= # show the attributes of user %>
   <% end %>

5. Add route for the post to url “/xxxxxx” (config/route.rb)

   match "/xxxxxx" => "yyyyyyy#zzzzzz"
