def self.directory_hash(path, name=nil)
data = {:parent => (name || path)}
data[:children] = children = []
Dir.foreach(path) do |entry|
next if (entry == '..' || entry == '.')
full_path = File.join(path, entry)
if File.directory?(full_path)
children << directory_hash(full_path, entry)
else
children << entry
end
end
return data
end
我使用了返回下面给出的 json 的上述方法:-
{:parent=>"public", :children=>["422.html", {:parent=>"applications", :children=>[{:parent=>"1", :children=>[{:parent=>"1", :children=>[{:parent=>"1", :children=>["configurations.xml"]}, {:parent=>"2", :children=>["configurations.xml"]}, "Projects.rar"]}, {:parent=>"2", :children=>[{:parent=>"9", :children=>["configurations.xml"]}, "rest.rar", {:parent=>"5", :children=>["configurations.xml"]}, {:parent=>"6", :children=>["configurations.xml"]}, {:parent=>"3", :children=>["configurations.xml"]}, {:parent=>"4", :children=>["configurations.xml"]}]}]}, {:parent=>"2", :children=>[{:parent=>"3", :children=>["Projects.rar"]}, {:parent=>"4", :children=>["rest.rar"]}]}]}, "500.html", "robots.txt", "favicon.ico", {:parent=>"data", :children=>[]}, "_index.html", "404.html"]}
现在在我看来,我想从上面的输出中显示结构,所以视图应该看起来像
public
422.html
applications
1
1
1
2
2
.....
.....
.....
一个这样的
我有一个变量来保存这个 json
@structure = ApplicationVersion.directory_hash("public")
那么我需要编写什么代码来读取上面的 json 以便可以构建树?
