什么是保存草稿帖子的 RESTful 方式? [英] what's a RESTful way to save draft posts?

问题描述

我正在制作的一个小型测试网站上有一个帖子控制器.我想为网站提供保存草稿"/组合自动保存功能，因为该网站将有很长的帖子，用户可能想要离开并回来完成.但是，我之前从未在 Rails 应用程序(或任何应用程序)中构建过自动保存/保存功能.什么是 RESTful 的好方法?

I have a posts controller on a small test website I'm making. I want to have a 'save draft'/combo-auto-save function to the site, as the site will have long posts that users may want to leave and come back to finish. However, I've never built an autosave/save function into a Rails app before (or any app). What is a good, RESTful way to do so?

这是我当前的控制器操作:

Here is my current controller action:

posts_controller.rb

posts_controller.rb

 def create

 @post = params[:post]
 if @post.save
     flash.now[:success] = "Post created!"
 else 
     render_errors_now(@post) 
 end
     respond_to do |format|
           format.html {redirect_to Discussion.find(session[:discussion_id])}
           format.js
     end
 end

如您所见，用户远程发帖.

As you can see, users post remotely.

这是当前的 post.rb 模型:

Here is the current post.rb model:

 attr_accessible :content, :title
 validates :title, :presence => true 
 validate :title_character_length

 validates :content, :length => { :maximum => 10000 }
 validates :user_id, :presence => true
 validates :discussion_id, :presence => true
 belongs_to :user
 belongs_to :discussion
 default_scope :order => 'posts.created_at ASC'

 def title_character_length
    #some code that checks length
 end

我需要从这段代码中完成以下事情..

I would need to accomplish the following things from this code..

1. 定期自动保存(可能间隔 1 分钟)
2. 提供保存草稿的选项
3. 选择要运行的验证:例如，我希望允许用户保存标题超过允许长度的草稿，但不允许他们实际发布具有该标题的帖子.

我也很好奇 Rails 保存草稿的良好做法是什么:我应该向后期模型添加属性草稿"吗?或者创建一个草稿帖子模型?

I also am curious what is a good Rails practice for saving drafts: should I add an attribute "draft" to the post model? Or create a draft posts model?

好的，如果我需要提供更多信息，请发表评论.我很想听听人们的意见！谢谢大家！

OK please comment if I need to provide more info. I'm interested to hear people's input! Thanks everyone!

推荐答案

自动保存:

application.js

$(document).ready(function() {
  setInterval(function() {
    $('form[data-remote]').submit();
  }, 1000*60); // 1000ms * 60s = 1m
});

然后您需要有一个 update.js.erb 来处理消息(例如已保存").

You'll then need to have an update.js.erb to handle the messages ("Saved", for example).

对于草稿，我会制作一个单独的模型，PostDraft.自动保存将保存 PostDraft 对象，然后一旦他们单击发布"或其他任何内容，它将创建一个新的 Post 并删除 PostDraft.此方法还将允许用户拥有超过限制的标题，只需不要将该验证放在 PostDraft 模型上.如果您在带有草稿"布尔值的 Post 模型中完成所有操作，这将变得更加困难.

For drafts, I would make a separate model, PostDraft. The auto-save will be saving the PostDraft object, and then once they click "Publish" or whatever, it will create a new Post and delete the PostDraft. This method will also allow the user to have titles longer than the limit, just by not putting that validation on the PostDraft model. This would be a lot more difficult if you did it all from within the Post model with a "draft" boolean.
