Day 8 - Profile Photo Upload and CRUD for Role and Task Management

In today's session of our Python Flask application development series, we're focusing on two pivotal features: Profile Photo Upload and CRUD operations for Role and Task management. Let's delve into each aspect step by step, starting with installation instructions:

1. Profile Photo Upload

   - Updating User Model: Begin by enhancing the `UserModel` schema to incorporate a new column named `photograph` for storing profile photo paths.
   
   - Database Migration: Execute Flask-Migrate commands to generate migration files and apply the necessary changes to the database schema. This ensures seamless integration of the new column.
   
   - Installation of Dependencies: Install the `uuid` library via the following command:
     ```bash
     pip install uuid
     ```
     The `uuid` library will be utilized to generate unique names for profile photos.
   
   - Image Resizing with Pillow: Install the `Pillow` library to facilitate image resizing capabilities:
     ```bash
     pip install Pillow
     ```
   
   - Configuration Setup: Define essential variables in the configuration file (`config.py`) including:
     ```python
     STATIC_FOLDER = os.environ.get('STATIC_FOLDER')
     PROFILE_PHOTO_DIR = os.getenv('PROFILE_PHOTO_DIR') or 'app/static/assets/profilephotos'
     ALLOWED_IMG_EXTENSIONS = os.getenv('ALLOWED_IMG_EXTENSIONS') or set(['png', 'jpg', 'jpeg', 'gif'])
     ```
   
   - Directory Creation: Create a directory named `profilephotos` inside the `static/assets` directory to store profile photos.
   
   - User Interface Enhancement: Integrate profile photo upload functionality into the application's user interface. This involves adding a link to the sidebar and defining the `uploadprofilephoto()` method in the `UserController`. Corresponding HTML views are created to facilitate this feature.

2. CRUD Operations for Role and Task Management

   - Role and Task Management: Implementing CRUD operations for managing roles, tasks, and assigning privileges to users.
   
   - Sidebar Navigation: Enhance user experience by adding links in the application's sidebar to access role and task management features conveniently.
   
   - HTML Views: Develop HTML views to provide intuitive interfaces for creating, reading, updating, and deleting roles and tasks.
   
   - Controller and Model Implementation: Create CRUD methods in the corresponding controllers (`RoleController` and `TaskController`) and define related functions in the model layer to handle business logic.

By following these steps and installation commands, you can elevate your Python Flask application's functionality with profile photo uploads and streamlined role and task management capabilities. Stay tuned for further enhancements in our application development journey!
