Description

Filled in the functions in availabilityHelper.ts
const createListOfUsersForShift = (shiftObject: Shift, entityState: EntityState, days: string[])

• given a list of users, returns a sorted list of available and eligible users
  const filterUsersByAvailability = (shiftObject: Shift, days: string[], entityState: EntityState)
• returns a list of user ids that are available to complete the shift
  const filterUsersByEligibility = (ids: EntityId[], entityState: EntityState, creditHours: number, shiftID: string)
• returns a list of user ids that are eligible (hoursUnassigned >= creditHours for the shift/already assigned to the shift)
  const sortUsersByNeededHoursAndPreference = (ids: EntityId[], entityState: EntityState, shiftObject: Shift)
• sorts users (first by preference), then by unassigned hours
• commented this out in shiftApiSlice because the schema should store all times in military format as strings
  // if (!entity.timeWindowDisplay) {
  // entity.timeWindowDisplay =
  // formatMilitaryTime(entity.timeWindow.startTime) +
  // ' - ' +
  // formatMilitaryTime(entity.timeWindow.endTime)
  // }

Next steps

stuff found: make sure firebase availabilities day (monday) is lowercase, shift times must be valid (end time and start time must have enough time to complete the shift-MUST BE ENFORCED IN THE SHIFT CREATION CARD)

// TODO: DOESN'T WORK IF SOMEONE IS ALREADY ASSIGNED DURING THEIR AVAILABILITY PERIOD TO A DIFFERENT SHIFT
