Calculate One Company By Date Range

Purpose:​

This function calculates attendance summaries for all users within a company for a given date range. It leverages caching to optimize performance.

Function Signature:​

func CalculateOneCompanyDateRange(companyID, start, end string, cache *caching.AllCacheStruct) ([]*entity.AttendanceSummariesTable, error)

Parameters:​

  • companyID: (string) Unique identifier for the company.

  • start: (string) String representation of the start date in a specific format (likely YYYY-MM-DD).

  • end: (string) String representation of the end date in a specific format (likely YYYY-MM-DD).

  • cache: (pointer to caching.AllCacheStruct) Optional cache object containing pre-calculated data.

Return Value:​

  • A slice of entity.AttendanceSummariesTable pointers representing the attendance summaries for all users within the company.

  • An error value indicating any issues during calculation.

Behavior:​

  1. Initialization:

    • An empty slice (summaries) is created to store the calculated attendance summaries.

    • If no cache is provided (cache == nil) or the existing cache is empty (cache.SummariesEmpty()), a new cache is prepared using prepareSummaryCache with force refresh (true) for both user schedules and summaries.

  2. Iterating Through Users:

    • A WaitGroup object (wg) is used to synchronize goroutine execution.

    • The function iterates through the user schedules stored in the cache (cache.Users.UserSchedulesOld).

      • For each user, it creates a new goroutine using a sync.WaitGroup.

      • Inside the goroutine:

        • The calculation for a single user's attendance summaries is performed using CalculateOnePersonDateRange.

        • If an error occurs during individual user calculation, it's logged but not returned immediately (err = nil). This behavior should likely be reviewed to handle errors appropriately.

        • Any calculated summaries for the user are appended to the summaries slice.

        • The time taken for each user calculation is printed for debugging purposes.

  3. Waiting and Returning Results:

    • The wg.Wait() method ensures all goroutines finish before returning.

    • The final list of summaries and any encountered error are returned.

Notes:​

  • This documentation assumes prepareSummaryCache and CalculateOnePersonDateRange functions exist but are not documented here.

  • Logging details and printing execution times are likely for debugging purposes and might not be included in the final production code.
