对于＃，未定义的方法`each'(undefined method `each' for #)

我希望有人可以提供帮助，我可以连接到soundcloud并获取一个项目列表，但它只是一堆文本。 当我尝试在列表中对它进行排序时，为#SoundCloud :: Client获取错误“undefined method` each'：0x87288f0>”

soundcloud控制器：

def self.search @client = Soundcloud.new(:client_id => ENV["SOUNDCLOUD_CLIENT_ID"]) end

search.html.erb

<!--this works--> <%= @client.get('/tracks', :q => 'some user') %> <!--this does not--> <% @client.each do |s| %> <ul> <li><%= s.get('/tracks', :q => 'some user') %></li> </ul> <% end %>

I hope someone can help, i can connect to soundcloud and get a list of items but it is just a bunch of text. when i try to order it in a list a get the error "undefined method `each' for #SoundCloud::Client:0x87288f0>"

soundcloud controller:

def self.search @client = Soundcloud.new(:client_id => ENV["SOUNDCLOUD_CLIENT_ID"]) end

search.html.erb

<!--this works--> <%= @client.get('/tracks', :q => 'some user') %> <!--this does not--> <% @client.each do |s| %> <ul> <li><%= s.get('/tracks', :q => 'some user') %></li> </ul> <% end %>

最满意答案

尝试这个：

<% @client.get('/tracks', :q => 'some user').each do |track| %> <ul> <li><%= track.title %></li> </ul> <% end %>

@client.get('/tracks', :q => 'some user')返回可以枚举的track对象的集合。

track对象本身并不是可枚举的，这就是为什么在尝试在其中一个上调用.each方法时会遇到错误的原因。

Try this:

<% @client.get('/tracks', :q => 'some user').each do |track| %> <ul> <li><%= track.title %></li> </ul> <% end %>

@client.get('/tracks', :q => 'some user') returns a collection of track objects which can be enumerated.

By themselves track objects are not enumerable and that is why you are getting error when trying to call .each method on one of them.
