如何查询具有空约会 ID 的 slot_details 的日程安排。这是一个示例数据集：

    id: 98,
  consulting_location_doctor_id: 498,
  schedule_date: Thu, 15 Jan 2015 00:00:00 IST +05:30,
  slot_details:
   [{"end"=>"2015-01-15T15:00:00.000+00:00", "start"=>"2015-01-15T14:30:00.000+00:00", "title"=>" 2:30 pm to  3:00 pm", appointment_id: ""},

我也尝试了指南中的示例。没有关于 json 数组 where 查询的示例。请帮忙。

也许这可以帮助你：

slot -> 'slot_details' @> '[{"end"=>"2015-01-15T20:00:00.000+00:00"}]'

这个想法是询问是否包含部分子数组。如果您不在对象中的数组 bun 中，则它将是（假设我们有一个配置文件对象）：

profile -> 'basics' @> '{"name":"john"}'

不要被愚弄试图在?这里使用而不是@>
