如何在 rails3 中呈现编辑视图和发布 Flash 消息 [英] How to render edit view and post flash message in rails3

问题描述

在我的帐户控制器中，我想在保存更改并显示 Flash 通知后显示(渲染、重定向到?)编辑视图.

In my account controller I'd like to display (render, redirect_to ?) the edit view after changes get saved and display flash notice.

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

    respond_to do |format|
      if @account.update_attributes(params[:account])
        format.html { redirect_to(@account, :notice => 'Account was successfully updated.') }

      else
        format.html { render :action => "edit" }
      end
    end
  end

推荐答案

默认情况下，您必须使用单独的语句，例如

By default you have to use a separate statement, e.g.

format.html { 
  flash[:notice] = 'message'
  render :edit
}

这张票 有一个补丁可以让你使用 render 'edit', :notice =>'消息'.它没有进入 Rails，但有一个 gem，flash_render，添加了它.

This ticket has a patch to let you use render 'edit', :notice => 'message'. It didn't get into Rails but there is a gem, flash_render, that adds it.
