代码redirect_to(@object)够用了吗
图片页面HTML代码简化清单
<div id="tabs">
  <ul>
    <li><a href="#tabs-1">公司</a></li>
    <li><a href="#tabs-2">员工</a></li>
    <li><a href="#tabs-3">集装箱</a></li>
  </ul>
  <div id="tabs-1">Company</div>
  <div id="tabs-2">Employee</div>
  <div id="tabs-3">Container</div>
</div>
  • 说明
    • 代码（一）是通过Rails命令scaffold自动生成代码，其中有一行代码“redirect_to @container”。这一行代码返回到页面，而不能够返回到该页面的某一个标签位置，如上图所示类似页面。如何办？
    • 代码（二）中代码“redirect_to container_path(@container, :anchor => “tabs-3”) ”就是解决这个问题的办法。
代码（一）
  # POST /containers
  # POST /containers.xml
  def create
    @container = Container.new(params[:container])    respond_to do |format|
      if @container.save
        flash[:notice] = 'Container was successfully created.'
        format.html { redirect_to @container) }
        format.xml  { render :xml => @container, :status => :created, :location => @container }
      else
        format.html { render :action => "new" }
        format.xml  { render :xml => @container.errors, :status => :unprocessable_entity }
      end
    end
  end
代码（二）
  # POST /containers
  # POST /containers.xml
  def create
    @container = Container.new(params[:container])    respond_to do |format|
      if @container.save
        flash[:notice] = 'Container was successfully created.'
        format.html { redirect_to container_path(@container, :anchor => "tabs-3") }
        format.xml  { render :xml => @container, :status => :created, :location => @container }
      else
        format.html { render :action => "new" }
        format.xml  { render :xml => @container.errors, :status => :unprocessable_entity }
      end
    end
  end
