Rails 重复记录未呈现新记录

Question

我想要的只是复制现有记录。它应该使用填充的数据呈现新表单，并让我“创建”这个新记录。

def clone
  @agreement = Agreement.find_by_slug!(params[:id])
  @agreement.clone

  respond_to do |format|
    format.html { render action: "new", notice: 'Agreement was successfully cloned.' }
  end
end

我的模型

def clone
  self.dup()
  self.slug = nil
end

出现此错误：

No route matches {:action=>"show", :controller=>"agreements", :format=>nil, :id=>#<Agreement id: 1, date: "2011-12-18",...`

路线

resources :agreements do
  member do
    post 'approve'
    get 'clone', :controller => 'agreements', :action => 'clone'
  end
end

Answer 1

我认为你的克隆方法应该是：

def clone
   clone = self.dup()
   clone.slug = nil
   clone
end

和控制器：

agreement = Agreement.find_by_slug!(params[:id])
@agreement = agreement.clone

ps: 为什么你在你的路由中指定控制器和操作。这是默认的情况，还是我遗漏了什么？
