渲染动作：在控制器的更新方法中编辑不重新渲染表单

Question

当用户使用编辑表单成功更新记录时，我希望它重新呈现带有通知的表单（就像 wordpress 仪表板一样）。现在，当有人成功更新页面记录时，视图不会更新。这是我的 Admin::Page 控制器中的更新方法：

def update
  @page = Page.find_by_permalink!(params[:id])
  if @page.published? && @page.published_at == nil
    @page.published_at = Time.now
  elsif !@page.published? && @page.published_at != nil
    @page.published_at = nil
  end
  if @page.update_attributes(page_params)
    render action: "edit", notice: 'Page was successfully updated.'
  else
    render action: "edit"
  end
end

我应该用什么来代替渲染动作：“编辑”？

Answer 1

试试这个：-

def update
  @page = Page.find_by_permalink!(params[:id])
  if @page.published? && @page.published_at == nil
    @page.published_at = Time.now
  elsif !@page.published? && @page.published_at != nil
    @page.published_at = nil
  end
  if @page.update_attributes(page_params)
    redirect_to({ action: 'edit',id: @page }, notice: 'Page was successfully updated.') #works on rails >=3.1 OR try the commented line below.
    #redirect_to edit_page_path(@page), notice: 'Page was successfully updated.'
  else
    render action: "edit"
  end
end

将 edit_page_path(@page) 更改为 编辑操作的路径。
