ruby-on-rails - 如何组织取决于提交值的重定向

Question

考虑一个博客应用程序，其中包含一个用于创建新帖子的表单。有两个按钮，“保存”，“保存并继续编辑”，保存后会相应地重定向用户。

这是代码：

def create
  @post = current_user.posts.build(params[:post])
  if @post.save
    if params[:commit] == "Create & continue editing"
      redirect_to edit_admin_post_path(@post), :notice => "Post record has been created"
    else
      redirect_to admin_posts_path, :notice => "Post record has been created"
    end
  else
    flash.now[:error] = "Post record has some validation errors"
    render :new
  end
end

这是做到这一点的最好方法，还是有其他方法可以重构它？

Answer 1

也许是这样的：

鉴于：

<%= submit_tag 'Save', name: 'save' %>
<%= submit_tag 'Save and continue editing', name: 'save_and_edit' %>

在控制器中：

def create
  @post = current_user.posts.build(params[:post])
  if @post.save
    redirect_to(params[:commit] == 'save' ? admin_posts_path : edit_admin_post_path(@post), notice: "Post record has been created")
  else
    flash.now[:error] = "Post record has some validation errors"
    render :new
  end
end
