Rabl和陣列陣列

Question

我找不到解決方案，所以我決定在這裏問。 我在此陣列（施工如果需要也可以改變）：

[[{:time=>2014, :amount=>148.24018480434023}, {:time=>2015, :amount=>152.5625744766238}], [{:time=>2014, :amount=>151.06717076828187}, {:time=>2015, :amount=>158.43869963240266}]] 

在Rabl的模板我有：

collection @array, object_root: false 

node :collection do |s| 
    s 
end 

，並且響應：

[{"collection": [{"time": 2014,"amount": 148.24018480434023},{"time": 2015,"amount": 152.5625744766238}]},{"collection": [{"time": 2014,"amount": 151.06717076828187},{"time": 2015,"amount": 158.43869963240266}]}] 

然而我想擺脫「收集」節點，並得到確切的迴應：

[ [{ time: 2014, amount: 138.92 }, { time: 2015, amount: 142.98 }], [{ time: 2014, amount: 141.57 }, { time: 2015, amount: 148.48 }] ] 

Answer 1

如果你想擺脫根的嘗試

# config/initializers/rabl_init.rb 
Rabl.configure do |config| 
    config.include_json_root = false 
    config.include_child_root = false 
end

Answer 2

我知道這是一個老問題，但爲後代着想。最簡單的方法是在節點調用中刪除：collection。因此，對於您的示例，它將如下

collection @array, object_root: false 

node do |s| 
    s 
end
