Ruby on rails 意外的JSON响应-Ruby on Rails

我有一个条形图，我正试图用

JSON

响应填充它。我正在使用带有内置JBuilder功能的Rails 5

这是我的密码：

def graph_data
  @customers = Customer.all
  @graph_data = {graph_type: "Customer Growth"}
  @months = {}
  x = 5
  while x >= 0
    @months[x.months.ago.strftime("%B")] = current_account.customers.where(:created_at => x.months.ago.beginning_of_month..x.months.ago.end_of_month).count
    x = x - 1
  end
  @graph_data[:months] = @months
  puts @graph_data.to_json

end

行

放置@graph\u数据。to\u json

输出以下文本：

{"graph_type":"Customer Growth","months":{"November":0,"December":0,"January":0,"February":0,"March":0,"April":3}}

正如我所料

但是，当我在

graph\u data.JSON.jbuilder

文件中输出实际的JSON响应时，输出是

[["graph_type","Customer Growth"],["months",{"November":0,"December":0,"January":0,"February":0,"March":0,"April":3}]]

我的目标是得到一个更像这样的回答：

{"graph_type":"Customer Growth","months":["November":0,"December":0,"January":0,"February":0,"March":0,"April":3]}

但我不知道如何用jBuilder实现这一点

下面是我的

graph\u data.json.jbuilder

文件的内容

json.array! @graph_data

---

提前感谢。

在jbuilder文件中，替换

json.array! @graph_data

到

json.graph_type @graph_data[:graph_type]
json.months @graph_data[:months]
