簡單搜索不能在rails中工作？

Question

我在這個railscast http://railscasts.com/episodes/37-simple-search-form?autoplay=true之後爲我的Procedure表建立了一個搜索機制。我幾乎跟着它究竟但是當我提交搜索我得到這個錯誤：

ActiveRecord::RecordNotFound at /procedures 

Couldn't find all Procedures with 'id': (all, {:conditions=>["name LIKE ?", "%Emergency%"]}) (found 0 results, but was looking for 2) 

我想按名稱搜索程序，而這個錯誤會使得它看起來就像是由ID搜索？

這裏是視圖：

 <%= form_tag procedures_path, :method => 'get' do %> 
     <p> 
     <%= text_field_tag :search, params[:search], :id => "welcome-search" %> 
     <%= submit_tag "Search Procedures", :name => nil, :class => "btn btn-success btn-lg" %> 

我的控制器：

def index 
    @procedures = Procedure.search(params[:search]) 
    render `procedures/index` 
end 

我的模型：

def self.search(search) 
    if search 
    find(:all, :conditions => ['name LIKE ?', "%#{search}%"]) 
else 
    find(:all) 
end 
end 

我很困惑，因爲railscast使得它看起來那麼容易得到工作..謝謝。

find(:all)已經很老了，因爲rails 3.2已經不再可用了。取而代之的是使用where：

def self.search(search) 
    if search 
    where('name LIKE ?', "%#{search}%") 
    else 
    all 
    end 
end
