我有一个搜索表单，可以按标签搜索图像。表单有点工作，它将参数发送到 /search_results 页面，但它发送如下：

search_results?utf8=✓&search=squid%2C+color&x=0&y=0

这是我的表格：

<%= form_tag ("/search_results"), :method => "get", :class=>"search_form" do %>
  <%= text_field_tag ("search"), nil, :class => 'search_input',
    :onblur=>"if(this.value=='')this.setAttribute('class', 'search_input');",
    :onfocus=>"this.setAttribute('class', 'search_input_clear');"
 %>
  <%= image_submit_tag("search.png") %>
<% end %>

和我的路线/控制器：

match "/search_results/" => "index#search_results", :via => :get, :as =>"search_results"
class IndexController < ApplicationController

def search_results
  @tattoos = Tattoo.tagged_with("%#{params[:search]}%")
end

但我从来没有得到任何结果。

Rails 控制台显示：

Parameters: {"utf8"=>"✓", "search"=>"color, animals", "x"=>"0", "y"=>"0"}
  SQL (0.5ms)  SHOW TABLES
  ActsAsTaggableOn::Tag Load (0.2ms)  SELECT `tags`.* FROM `tags` WHERE (name LIKE '\\%color' OR name LIKE 'animals\\%')
  SQL (0.1ms)  SELECT COUNT(*) FROM `tattoos` WHERE (1 = 0)
  Tattoo Load (0.3ms)  SELECT `tattoos`.* FROM `tattoos` WHERE (1 = 0) ORDER BY tattoos.created_at DESC

我删除了参数周围的 % ，这似乎可以解决问题：

def search_results @tattoos = Tattoo.tagged_with("#{params[:search]}") 结束
