rails重复记录不呈现新 [英] rails duplicate record not rendering new

问题描述

所有我想要的是现有记录的重复。它应该使用填充数据呈现新表单，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，注意：协议已成功克隆} 
 end 
 end 
  

我的模型

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

我收到这个错误： / p>

 没有路由匹配{：action =>show，：controller =>协议，：format => nil，：id =>＃<协议ID：1，日期：2011-12-18，... 
  

路线

 资源：协议做
会员做
帖子' '
 get'clone'，：controller => 'agreement'，：action => 'clone'
 end 
 end 
  

解决方案

p>我认为你的克隆方法应该是：

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

而控制器： / p>

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

ps：为什么在路由中指定控制器和操作。这是默认的，或者我缺少什么？

all I want is duplicate an existing record. It should render new form with populated data and let me 'Create' this new record.

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

My Model

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

I get this error:

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

Routes

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

解决方案

I think your clone method should be:

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

And the controller:

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

ps: Why do you specify the controller and action in your routes. It's what the default would be, or am I missing something?
