SImple Rails搜索

我生成了一個search_contoller並查看我的rails應用程序。SImple Rails搜索

我的控制器：

class SearchController < ApplicationController 

    def index 
    if params[:commit] == "Search" 
     # Great, now lets figure out what sort of query we're after 
     @searchQuery = params[:q] 
     @resultsReceived = true 
     if 
     @sqlResults = Product.where("title like ? OR categories like ?", "%" + params[:q] + "%", "%" + params[:q] + "%").order("published DESC") 
     end 
    else 
     @resultsReceived = false 
     @sqlResults = [] 
    end 

    # Render the page when we're done. 
    respond_to do |format| 
     format.html 
    end 
    end 
end

我查看

<%= form_tag("/search", :method => "get") do %> 
    <%= label_tag(:q, "Search for:") %> 
    <%= text_field_tag(:q) %> 
    <%= submit_tag("Search") %> 
<% end %> 

<% if @resultsReceived == true %> 
<b><%= @sqlResults.length %> Results Found For: </b><%= @searchQuery %> 
<br> 
<table> 
    <tr> 
    <th>Publish</th> 
    <th>Product</th> 
    <th></th> 
    </tr> 
<% @sqlResults.each do |product| %> 
<tr class="<%= cycle('oddrow', 'evenrow') %>"> 
     <td><%= check_box_tag "product_ids[]", product.id, product.published, {:id => product.id, :class => "publish_checkbox"} %></td> 
     <td><%= link_to 'Edit', edit_product_path(product) %></td> 
     <td><%= link_to 'Destroy', product, confirm: 'Are you sure you want to KILL this product?', method: :delete %></td> 

     <td> 
     <div> 
      <b>Title:</b> <%= product.title %> 
     </div> 

     <div class="float_left prod_image"> 
      <a href='<%= product.url %>' target="_blank"><img src='<%= product.image_url %>' class='product_image'></img></a> 
     </div> 
     <div class="float_left prod_description"> 
      <div><b>Product is Published: </b> <%= product.published %></div> 
      <div><b>Category Names:</b> <%= product.category_names %></div> 
      <div><b>Categories:</b> <%= product.categories %></div> 
      <div><b>Rating:</b> <%= product.rating %></div> 
      <div><b>Wow:</b> <%= product.is_curated %></div> 
      <div><b>Age:</b> <%= product.pr_attributes['ag_type'] %></div> 
      <div><b>Gender:</b> <%= product.pr_attributes['gender_type'] %></div> 
      <div> 
      <b>Description:</b> 
      <% if product.long_descr.length < 200 %> 
       <%= product.long_descr %> 
      <% else %> 
       <span id="short_desc_<%= product.id %>"><%= product.long_descr[0..199] %>...</span> 
       <span class="long_description", id="long_desc_<%= product.id %>"><%= product.long_descr %> </span><a id="<%= product.id %>" class="toggle">toggle</a> 
      <% end %> 
      </div> 
     <div><b>Backfill Male:</b> <%= product.backfill_text['male'] %></div> 
     <div><b>Backfill Female:</b> <%= product.backfill_text['female'] %></div> 
     <div><b>Backfill Unisex:</b> <%= product.backfill_text['unisex'] %></div> 
     <div><b>MP Seller Name:</b><%= product.mp_seller_name %></div> 
      <div><b>Price:</b> Current: $<%= product.curr_item_price %>/Base: $<%= product.base_item_price %></div> 
     <div><b>ID STR:</b> <%= product.id_str %></div> 
     <div><b>Stock:</b> <%= product.stock_status %></div> 
     <div><b>Last Updated by <%= product.updated_by_name %> at <%= product.updated_at %></b></div> 
     </div> 
</tr> 

<% end %> 
<% end %>

我需要的搜索更加具體，並想分手的sql語句，這樣我就可以搜索其他附加的屬性。例如，我希望搜索TITLE（並獲得僅匹配用戶輸入的字符串的結果）或通過GENDER搜索（僅返回用戶搜索的性別）。我怎樣才能做到這一點？我應該爲每種我想執行的搜索類型創建新的form_tags嗎？是否有可能在視圖中只有一個搜索框，並讓用戶在單選按鈕之間選擇他們想要搜索的內容？
