This project collects weather data using Python, Flask and PostgreSQL. It periodically fetches real-time data from a Weather API, stores it in PostgreSQL, and returns the weather data for a specific city.

Prerequisites

Before you begin, ensure you have the following installed and set up on your development environment:

• Python: Version 3.12.4 or higher.
• PostgreSQL: Ensure you have PostgreSQL installed and running locally. You can download it from PostgreSQL Downloads.
• (https://www.postgresql.org/download/) is the URL to the PostgreSQL Downloads page.

Installation

1 - Clone the Repository:

• git clone https://github.com/sabrahermassi/weather-data-collection-and-fetching.git
• cd weather-data-collection-and-fetching

2 - Install Python Dependencies: Install project dependencies using pip, this will install all required Python packages listed in requirements.txt.

• python -m pip install --upgrade pip
• pip install -r requirements.txt

Configuration

1 - Set Up Database Configuration: Create a test_database.ini file in the root directory for testing purposes:

• main_database: First section for the postgres main database running on your computer
• host: The hostname of the postgres database
• port: The port number of the postgres database
• database: The name of your main postgres database
• user: The user name of the postgres database
• password: The password created for the postgres database
• test_weather_database: Second section for the test database you created
• host: The hostname of the test database
• port: The port number of the test database
• database: The name of your test database
• user: The user name of the test database
• password: The password created for the test database

2 - Set Up Environment Variables: Create a .env file in the root directory with the following content (Update API_KEY with your actual API key for weather data access.):

• API_KEY : your api key from the weather API of your choice
• API_BASE_URL : URL to the weather API of your choise

Usage

• To start the application, run: python api/app.py
• To run unit tests, use: pytest tests/unit
