是否正在阅读文件？

# devices_controller.rb
def index
  @data = JSON.parse(File.read(File.join('assets/javascript/folder', 'myjson.json')))
  ...
end

您将把它用作您可以在视图中使用的ruby变量。

更新

# inside devices_controller.rb

def index
  # place the file under public folder
  @dealers = JSON.parse(File.read(File.join('public','dealers.json')
  ...
end

# inside devices/index.html.erb
...
<p><%= @dealers['records']['id'] %></p>
...
