資料分析-A. 相機工作時數 about camera-trap-api

[kelp404]

功能是這樣對嗎？

要做兩個 API，輸入欄位都有 project id，計算總時數的 API 還需要開始時間、結束時間。

計算每月工作時數：

從 ProjectTripModel 以 studyAreas.cameraLocations.cameraLocation 以及月份做 group-by，統計每個月的 startActiveDate 到 endActiveDate 經過的小時數。

計算範圍內總時數：

從 ProjectTripModel 以 studyAreas.cameraLocations.cameraLocation 做 group-by 在時間範圍內統計 startActiveDate 到 endActiveDate 經過的小時數。

輸入欄位

1. 都有 project id (array)
2. 開始時間 start_time、結束時間 end_time
3. 基本上 filter 的條件都要有 (但若太多、其他條件可先不加、之後我們再 query 加上)
