Credentials Management

These scripts need 2 kinds of credentials:

1. Cosec's credentials for automating browser behaviour for report fetching,
2. The CA Office's credentials for sync'ing data between Cosec and TCAOFF

Credentials are not sync'ed through Git or any other versioning system for security purposes. You must manually create the credential files (JSON format).

Here are templates for both (⚠️ ONLY MODIFY WHAT HAS BEEN INDICATED):

👉 Cosec Credentials

These have to be stored in <proj-dir>/creds/cosec.json

{
    "creds": {
        "url": "http://x.x.x.x/COSEC/",  // ... put the IP address here
        "username": "<usr>",  // .............. put your value here
        "password": "<pwd>"  // ............... put your value here
    },
    "generalConfig": {
        "pollInterval": 3600,
        "timezone": "Asia/Kolkata",
        "timedelta": {
            "days": 0,
            "hours": 36,
            "minutes": 0,
            "seconds": 0
        }
    },
    "musterRollConfig": {
        "groupIds": ["2", "3", "4"]  // ... whichever orgs you need to monitor
    },
    "inOutConfig": {
        "groupIds": ["2", "3", "4"]  // ... whichever orgs you need to monitor
    }
}

👉 The CA Office (TCAOFF) Credentials

These have to be stored in <proj-dir>/creds/tcaoff.json

{
    "creds": {
        "username": "<usr>",  // ... put your value here
        "password": "<pwd>",  // ... put your value here
        "sessionToken": null,
        "user": null 
    },
    "urls": {
        "login": "https://api.thecaoffice.com/ca/login",
        "logout": "https://api.thecaoffice.com/user/logout",
        "branchList": "https://api.thecaoffice.com/commons/branch/list",
        "branchAdd": "https://api.thecaoffice.com/commons/branch/add",
        "deptList": "https://api.thecaoffice.com/commons/departments/list",
        "deptAdd": "https://api.thecaoffice.com/commons/departments/add",
        "teamList": "https://api.thecaoffice.com/team/list",
        "teamAdd": "https://api.thecaoffice.com/team/add",
        "teamUpdate": "https://api.thecaoffice.com/team/update",
        "attendanceList": "https://api.thecaoffice.com/user/attendance/register",
        "attendanceMark": "https://api.thecaoffice.com/user/attendance/mark"
    }
}

Selenium Web Driver Management

Where To Get The Latest Drivers From

You can download the latest Chrome drivers from this page.

Alternately, you can receive a well-structured JSON dump of the known good versions with their respective download links from this URL.

👉 Where To Place The Drivers

Matrix refused to give APIs for accessing data from their Cosec system. Selenium is being used for web browser automation as a solution. We chose Chrome as the web browser for this since it is very widely available and most supported by a huge margin.

Browser automation needs corresponding drivers and drivers need be maintained based on 2 factors:

1. OS/platform that they will be running on,
2. the version that your browser is running on.

When you update the browser on your device, you will end up with a mismatch between the actual browser's version and the driver's version. It is possible that you will need to manually download the latest driver and put it in the appropriate path. Here are the paths:

• Windows Driver: <proj-dir>/drivers/chrome/win64/chromedriver.exe
• Linux Driver: <proj-dir>/drivers/chrome/linux64/chromedriver

You can check the version of Chrome on your device by going to Settings 👉 About Chrome. You will be able to see your browser's version and it will be something like Version 143.0.7499.193 (Official Build) (64-bit).

Running The Scripts

⚠️ NOTE: Ensure that the virtual environment is activated before running the Python script. The .sh files enable the virtual environment automatically, you need not worry when running them.

👉 Running APIs That Are Called From TCAOFF's Frontend

Run the file <proj-dir>/backend/api/main.py, or <proj-dir>/run_api.sh

👉 Running The Cron Script That Fetches Reports Periodically

Run the file <proj-dir>/cron/reports.py, or <proj-dir>/run_cron.sh

👉 Running The Manual Attendance Script

Run the file <proj-dir>/cron/attendance.py with the args --date <yyyy-mm-dd>, or run <proj-dir>/run_cron.sh and it will prompt you to type the date.
