Question

我现在有一个简单的搜索表单，它将搜索模型中的一列并按预期返回结果，但是我希望通过能够使用4 text_field / Select_tags搜索同一模型中的4列来构建此基础。

我已经看过Gems，它提供了类似于solr的例子，但我的想法是，对于我想要实现的目标，它似乎有点过分，特别是在如此小的应用程序上

应用程序很简单，您可以上传食谱，将食谱添加到收藏夹和搜索食谱。

到目前为止它看起来像这样

控制器

 def search
 @countrysearch = Recipe.where(:country_of_origin => params[:search]).all
 end

搜索表单

 <%= form_tag({:controller => 'search', :action => 'search'}, {:method => 'get'})  do |s| %>
 <%= text_field_tag :search, params[:search] %>
 <%= submit_tag "Search" %>
 <% end %>

输出（查看）

  <% @countrysearch.each do |r| %>
  <tr>
   <td><%= r.dish_name %></td>
   <td><%= r.country_of_origin %></td>
   <td><%= r.difficulty %></td>
   <td><%= r.preperation_time %></td>
   <td><%= ingredient_names(r.ingredients) %></td>
   <td><%= preperation_steps(r.preperations) %></td>
 </tr>

我希望我的搜索表单能够使用选择标记来反映我的“创建新配方表单”

  <%= f.label :dish_name, "Dish Name" %>
  <%= f.text_field :dish_name, :placeholder => "Enter Dish Name" %>

  <%= f.label :country_of_origin, "Country Of Origin" %>
  <%= f.select :country_of_origin,  [['Wales'],['Scotland'],['England']], {:include_blank => 'Please Select'} %>

  <%= f.label :difficulty, "Difficulty Level" %>
  <%= f.select :difficulty, [['Beginner'],['Intermediate'],['Expert']], {:include_blank => 'Please Select'} %>


  <%= f.select :preperation_time, [['15..30'],['30..60'],['60..120']], {:include_blank => 'Please Select'} %>


 <% end %>

只是在正确的方向上的一些指示将不胜感激。谢谢

您可以使用传递给控制器的所有参数来执行此操作：

def search
 @countrysearch = Recipe.where({:dish_name => params[:search][:dish_name], :country_of_origin => params[:search][:country_of_origin], :difficulty => params[:search][:difficulty], :preperation_time => params[:search][:preperation_time]}).all
end

这对你有用。还有其他选择，但如果你想要一个简单的选择，这可能适合你。

修改

如果您在搜索中没有其他内容，可以执行以下操作：

<%= form_tag({:controller => 'search', :action => 'search'}, {:method => 'get'}) do |s| %> <%= text_field_tag :dish_name, params[:dish_name] %> <%= select_tag "country_of_origin", options_from_collection_for_select(@recipes, "country_of_origin", "country_of_origin_name") <%= select_tag "difficulty ", options_from_collection_for_select(@recipe, "difficulty ", "difficulty ") <%= select_tag "preperation_time", options_from_collection_for_select(@recipe, "preperation_time", "preperation_time") <%= submit_tag "Search" %> <% end %>

然后在控制器中直接传递参数

def search @countrysearch = Recipe.where(params).all end

在模型导轨中搜索多个列3
