当操作依赖于传递的参数时，如何使用redirect_to？

问题描述

当Edit操作依赖于传递的参数时，如何使用redirect_to？

我有两个非常简单的操作编辑和更新。一旦我点击提交，在更新后，我想将用户重定向到编辑操作。如果编辑操作需要参数，如何执行此操作？

  def edit 
 @account = Account.find_by_user_id @params ['user_id']）
 end 
 
 def update 
 account = Account.find（params [：account_user_id]）
 
如果是帐户。 update_attributes（params [：name]）
 redirect_to params [：user_id] .merge！（：action =>：edit）
 else 
 render：text => '对不起，更新时出错。'
 end 
 end 
  

$ b



  redirect_to edit_account_path（account.id，：user_id => params [：user_id]）
  / pre> 
 
 
我假设你在这里将你的路由声明为 resources：accounts  
 
How do you use redirect_to when the Edit action is dependent on a parameter being passed?

I have two very simple actions edit and update. Once I click submit, following an update I'd like to redirect the user back to the edit action. How do I do this if the edit action requires a parameter?
  def edit
    @account = Account.find_by_user_id(@params['user_id'])
  end

  def update
    account = Account.find(params[:account_user_id])

       if account.update_attributes(params[:name])
        redirect_to params[:user_id].merge!(:action => :edit)
       else
         render :text => 'Sorry there was an error updating.'
       end
  end
this code blows up
 解决方案 
Try the following:
 redirect_to edit_account_path( account.id, :user_id => params[:user_id])
I assume here you declared your routes as resources :accounts
