ActiveModel :: Serializer进行排序和序列化(ActiveModel::Serializer sort and serialize)

 例如我有两个activeRecord模型：  
class Article < ActiveRecord::Base
  has_one :article_poster
end
 
 和  
class ArticlePoster < ActiveRecord::Base
  belongs_to :article
end
 
 在某些控制器中：  
CustomSerializer.new(articles)
 
 CustomSerializer：  
class CustomSerializer < ActiveModel::Serializer
end
 
 我有4篇文章，有海报，没有它。 例如： 
 第一篇文章海报礼物 
 第二篇文章海报不存在 
 第三篇文章海报礼物 
 第4条海报礼物 
 
 我需要海报存在的文章：1,3,4,2。 在CustomSerializer或Article模型中实现它的最佳方式是什么？ 

for example i have two activeRecord models: 
class Article < ActiveRecord::Base
  has_one :article_poster
end
 
and 
class ArticlePoster < ActiveRecord::Base
  belongs_to :article
end
 
In some controller: 
CustomSerializer.new(articles)
 
CustomSerializer: 
class CustomSerializer < ActiveModel::Serializer
end
 
I have 4 articles, with poster and without it. For example: 
 1st article poster present
 2nd article poster NOT present
 3rd article poster present
 4th article poster present
 
I need articles in order by poster presence: 1,3,4,2. What is the best way to implement it in CustomSerializer or in Article model?

 将文件放在/ usr / share / vim / vimfiles / ftdetect（用于全局）或.vim / ftdetect（用于本地）中，名为Rnw.vim，如下所示：  
" Vim filetype detection plugin
" Language:    sweavefile

autocmd BufRead,BufNewFile *.Rnw set filetype=tex
 
 编辑：我很确定你也可以把这个自动命令放在你的.vimrc中，因为在加载任何文件之前它已经在程序启动时加载了，但是这个目录是文件类型检测的自然场所。  
 编辑：如果您想给这些文件一些不同于TeX的处理，您可以将文件类型设置为rnw，根据需要将脚本添加到ftplugin，缩进和语法目录，最有可能获取TeX脚本然后自己编写东东。 

Put a file in /usr/share/vim/vimfiles/ftdetect (for global) or .vim/ftdetect (for local) called Rnw.vim that looks something like this: 
" Vim filetype detection plugin
" Language:    sweavefile

autocmd BufRead,BufNewFile *.Rnw set filetype=tex
 
Edit: I'm pretty sure you could put this autocommand in your .vimrc too, since that's loaded on program start, before any files are loaded, but this is directory the natural place for filetype detection. 
Edit: If you would like to give these files some treatment different from TeX, you could instead set the filetype to rnw, add scripts to the ftplugin, indent, and syntax directories as necessary, most likely sourcing the TeX scripts and then doing your own stuff.
