The Problem: You’re trying to automatically update an employee calendar based on Google Form submissions, but you’re struggling to correctly identify and update the cells corresponding to an employee’s leave dates. Your current code finds the employee and the date range, but it’s missing the crucial step of mapping those to the correct cells on the calendar sheet.
Understanding the “Why” (The Root Cause):
The core issue lies in correctly translating the date range from the form submission into the corresponding column indices on your calendar sheet. Your dateHeaders array contains the date strings, but you need a way to efficiently find the column index for a given date within that array. Directly comparing dates as strings is prone to errors due to potential formatting inconsistencies and time zone differences. A more robust approach involves iterating through the date range and efficiently searching for the corresponding column for each date.
Step-by-Step Guide:
Step 1: Efficiently Find the Column Index for Each Date:
The provided solution suggests using a while loop to iterate through the date range and using the indexOf() method to search for the date in the dateHeaders array. This approach requires careful date formatting to ensure accurate matches. Instead of relying on string comparison, converting dates to a consistent numerical representation (milliseconds since epoch) provides a more robust comparison.
Here’s the improved code:
function updateCalendar(){
// ... (Your existing code to get form data and employee lists remains unchanged) ...
for(var j = 0; j<employeeList.length; j++){
if (status === "Approved" && employeeList[j][0] === employeeName){
let currentDate = new Date(startDate);
while (currentDate <= endDate) {
const dateString = Utilities.formatDate(currentDate, Session.getScriptTimeZone(), 'yyyy-MM-dd');
const columnIndex = dateHeaders[0].indexOf(dateString);
if (columnIndex !== -1) {
employeeCalendar.getRange(j + 3, columnIndex + 3).setValue(leaveType);
} else {
Logger.log('Date not found in header: ' + dateString); //handle dates not in header
}
currentDate.setDate(currentDate.getDate() + 1);
}
};
};
};
This revised code iterates through the date range, converts each date to a consistent yyyy-MM-dd format using Utilities.formatDate(), and then uses indexOf() to find the corresponding column index in the dateHeaders array. The if statement ensures that only dates present in the header are updated, preventing errors. The Logger.log statement provides debugging information if a date is missing from the header.
Step 2: Handle Leave Type Mapping:
Before updating the calendar, you might want to map the leaveType values from the form to the single-character codes you’re using (“V”, “H”, “S”, etc.). You can achieve this using a simple object:
const leaveTypeCodes = {
"Vacation": "V",
"Sick Leave": "S",
"Holiday": "H",
// Add other leave types here
};
// ... inside the loop ...
let leaveCode = leaveTypeCodes[leaveType] || "U"; //Default to "U" if leaveType is unknown.
employeeCalendar.getRange(j + 3, columnIndex + 3).setValue(leaveCode);
// ... rest of the code
This code ensures that the correct single-character code is used for each leave type.
Common Pitfalls & What to Check Next:
- Date Formatting: Double-check that the date format in your
dateHeaders array exactly matches the format created by Utilities.formatDate(currentDate, Session.getScriptTimeZone(), 'yyyy-MM-dd'). Any inconsistencies will lead to incorrect column indexing.
- Time Zone: Ensure that the time zone used in
Utilities.formatDate (Session.getScriptTimeZone()) is consistent with the time zone used in your Google Sheet and form.
- Error Handling: The added
if (columnIndex !== -1) check and Logger.log statement provides basic error handling. Consider more robust error handling for scenarios where dates are missing or unexpected data is encountered in the form submission.
- Data Validation: Add data validation to your Google Form to ensure that users enter dates and leave types correctly.
- Leave Type Codes: Expand the
leaveTypeCodes object to include all possible leave types from your form.
