我正在尝试格式化json响应,删除不需要的字段以获得较小的响应(即created_at和updated_at)
我目前正在这样做:
friends = @user.friends
friends.each do |f|
f[:name] = f.user.username # adding arbitrary attribute needed in the response
end
render :json => friends.as_json(:except => [:created_at, :updated_at])
created_at和updated_at仍然包含在响应中,我做错了什么?

:except
不会处理嵌套在数组中的属性。你可以在实例上使用它:
friends = @user.friends.map do |f|
f[:name] = f.user.username # adding arbitrary attribute needed in the response
f.as_json(:except => [:created_at, :updated_at]
end
render :json => friends
