Installation

Ready to get started? Setting up this travel blog project on your local machine is straightforward. Follow these steps to get it up and running:

1. Clone the Repository
2. Install Dependencies
3. Set up Environment Variables
4. Configure .gitignore
5. Run the Application

Step 1: Cloning the Repository

Begin by cloning the project repository to your local environment. This action downloads all the necessary files to your computer, allowing you to work on the codebase directly. If you’re also planning to contribute or keep track of your modifications, consider forking the repository on GitHub and cloning your fork. For guidance on cloning and pushing to your own repository, this Stack Overflow answer provides a comprehensive explanation.

Step 2: Installing Dependencies

Once you’ve cloned the repository, navigate into the project directory using your command line interface. Inside, you’ll find a requirements.txt file. This file lists all the Python packages that the Flask blog application depends on. To install these, use pip, Python’s package installer, with the command:

pip install -r requirements.txt

This command reads the requirements.txt file and installs all listed libraries, ensuring you have all the necessary tools to run the Flask application. If you modify the project and add new dependencies, you can update this file by running pip freeze > requirements.txt. This command captures your current Python environment’s packages and their versions, updating the requirements file accordingly. This is useful for maintaining consistent environments across different setups.

Step 3: Create a .env File

For security and configuration management, create a .env file in the root directory of your blog_flask project. This file will store sensitive information, such as your email credentials, needed for the contact form feature. Add the following variables to your .env file, replacing the placeholders with your actual Gmail address and app password:

EMAIL_ADDRESS = "[email protected]"
EMAIL_PASSWORD = "your_gmail_app_password"

These credentials are used for sending emails through the blog’s contact form. The application uses Gmail’s SMTP server to send these emails. If you intend to use a different email provider, you would need to adjust the SMTP server settings in app/website/contact.py. It’s crucial to use an app password instead of your regular Gmail password, especially if you have two-factor authentication enabled on your Gmail account. Google’s support page on Sign in with App Passwords provides detailed instructions on how to generate an app password. Storing these sensitive details in a .env file and excluding it from version control is a best practice to prevent accidental exposure of your credentials.

Step 4: Create a .gitignore File

To prevent unnecessary and sensitive files from being committed to your Git repository, create a .gitignore file in the root directory of your blog_flask project. Add the following entries to your .gitignore file:

instance/
.env
__pycache__/

These entries ensure that the instance folder (which contains the SQLite database), the .env file (containing sensitive credentials), and Python’s cache files are not tracked by Git. Using a .gitignore file is essential for keeping your repository clean and secure. You can also find more comprehensive .gitignore templates online, tailored for Python or Flask projects, to further refine your ignored files list.

Step 5: Run the App

With all configurations in place, you’re now ready to run the Flask application. Execute the run.py file from your terminal within the project directory using the command:

python run.py

This command starts the Flask development server. Open your web browser and navigate to http://127.0.0.1:5000/ or http://localhost:5000/. You should now see your travel blog application live and running in your browser. Before diving into customizations, it’s recommended to review the code overview and especially the database changes section to understand the project’s structure and database setup.

Admin and Super Admin

Administrators are crucial for maintaining the blog’s content quality and user community. Their primary responsibilities include user and post management, acting as content moderators to ensure the blog remains a positive and informative space. A single super-admin user holds the highest level of control, capable of managing all aspects of the blog, including other admin accounts. Admins can approve, disapprove, edit, and delete blog posts. Only posts that are approved by an admin and meet their scheduled publish date will appear on the live blog.

Account Blocking and Deletion

To maintain community standards, the blog includes features for account blocking and deletion. When an account is blocked, the user loses all access to their account functionalities. Their past comments and replies are anonymized, appearing as “removed” in comment threads. While any admin can block or unblock regular users and authors, super-admin privileges are required to manage admin-level accounts.

Account deletion permanently removes user information from the system. In comment sections, a deleted user’s name and comment text are replaced with ‘deleted’ to maintain conversation flow. This ensures context is preserved even after a user’s departure. If a comment or reply stands alone and doesn’t affect conversation flow, it is fully removed. To preserve content continuity when an author is deleted, their posts are reassigned to a default ‘Travel Blog Team’ user. This approach ensures that valuable content remains accessible even if the original author is no longer part of the blog team.
