+# onboarding_system
+
+This project automates the synchronization of local folders (`attachments` and `onboarded_person`) with corresponding directories in a Nextcloud instance. It checks for new or modified files in local folders and uploads them to the designated Nextcloud directories, using a persistent session for efficient authentication. Additionally, it includes features for email notification and PDF generation from HTML templates and CSV files.
+
+## Features
+- Generate pdf from the dynamic CSV file.
+- Send email to to the recipient when it is necessary.
+- Automatically syncs files between local folders and Nextcloud.
+- Uploads only new or modified files to Nextcloud.
+- Processes CSV attachments from emails to generate PDFs.
+- Sends email notifications based on specific CSV content.
+- Configurable synchronization interval (default is 60 seconds).
+- Uses a persistent HTTP session for efficient communication with Nextcloud.
+- Tracks files locally to prevent re-uploading of unchanged files.
+
+## Requirements
+
+- Python 3.8+
+- Required Python libraries:
+  - `requests`
+  - `python-dotenv`
+  - `HTTPBasicAuth` (from `requests`)
+  - `pandas`
+  - `jinja2`
+  - `pdfkit`
+  - `PyPDF2`
+  - `imaplib`
+  - `email`
+  - `smtplib`
+
+## Setup
+
+### Step 1: Clone the Repository
+
+```bash
+git clone https://github.com/Bostame/onboarding_system.git
+cd onboarding_system
+```
+
+### Step 2: Install Dependencies
+
+Make sure you have Python 3.8+ installed. Use the following command to install dependencies:
+
+```bash
+pip install -r requirements.yml
+```
+
+### Step 3: Configure Environment Variables
+
+Create an `.env` file inside the `env/` directory with the following content:
+
+```env
+# Nextcloud credentials and URLs
+NEXTCLOUD_BASE_URL=https://your-nextcloud-url/remote.php/dav/files/your-user
+NEXTCLOUD_USERNAME=your-username
+NEXTCLOUD_PASSWORD=your-password
+NEXTCLOUD_DIRECTORY=Group-on-off-boarding
+
+# Sync interval in seconds (default: 60 seconds)
+SYNC_INTERVAL=60
+
+# Local folder paths
+TEMPLATES_DIR=templates
+ATTACHMENTS_DIR=attachments
+ONBOARDED_DIR=onboarded_person
+TEMP_PDF_DIR=temp_pdf
+EMAIL_TEXT_DIR=email_text
+
+# Email details (if applicable)
+IMAP_SERVER=imap.example.com
+SMTP_SERVER=smtp.example.com
+EMAIL_PORT=465
+EMAIL_ACCOUNT=your-email@example.com
+PASSWORD=your-email-password
+MINUTH_EMAIL=minuth@example.com
+DRITICH_EMAIL=dritich@example.com
+```
+
+### Step 4: Create Local Folders
+
+Ensure the following local directories exist:
+
+- `attachments/`
+- `onboarded_person/`
+- `templates/`
+- `temp_pdf/`
+- `email_text/`
+
+You can modify these folder paths via the `.env` file as needed.
+
+### Step 5: Run the Script
+
+To manually run the synchronization and CSV processing:
+
+```bash
+python sync_script.py
+python main.py
+```
+
+### Creating Systemd Service Units
+
+To continuously run the synchronization and processing in the background, create systemd service units.
+
+#### Step 1: Create the `onboarding-system.service` and `nextcloud-sync.service` Unit
+
+1. Create a service file:
+
+```bash
+sudo nano /etc/systemd/system/onboarding-system.service
+sudo nano /etc/systemd/system/nextcloud-sync.service
+```
+
+2. Add the following content to the file:
+
+```ini
+[Unit]
+Description=Nextcloud Folder Sync Service
+After=network.target
+
+[Service]
+User=root
+Environment="PATH=/root/miniconda3/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
+WorkingDirectory=/path/to/your/project
+ExecStart=/bin/bash -lc 'source /root/miniconda3/etc/profile.d/conda.sh && conda activate csv_pdf && /root/miniconda3/envs/csv_pdf/bin/python main.py'
+Restart=always
+
+[Install]
+WantedBy=multi-user.target
+```
+and
+
+```ini
+[Unit]
+Description=Nextcloud Folder Sync Service
+After=network.target
+
+[Service]
+User=root
+Environment="PATH=/root/miniconda3/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
+WorkingDirectory=/path/to/your/project
+ExecStart=/bin/bash -lc 'source /root/miniconda3/etc/profile.d/conda.sh && conda activate csv_pdf && /root/miniconda3/envs/csv_pdf/bin/python sync_script.py'
+Restart=always
+
+[Install]
+WantedBy=multi-user.target
+```
+
+3. Save the file and close it.
+
+#### Step 2: Reload Systemd Daemon
+
+```bash
+sudo systemctl daemon-reload
+```
+
+#### Step 3: Enable the Service
+
+```bash
+sudo systemctl enable onboarding-system.service
+sudo systemctl enable nextcloud-sync.service
+```
+
+#### Step 4: Start the Service
+
+```bash
+sudo systemctl start onboarding-system.service
+sudo systemctl start nextcloud-sync.service
+```
+
+#### Step 5: Check the Service Status
+
+```bash
+sudo systemctl status onboarding-system.service
+sudo systemctl status nextcloud-sync.service
+```
+
+### Logging
+
+To view logs for the `nextcloud-sync` service, use the following command:
+
+```bash
+journalctl -u nextcloud-sync.service
+```
