This is a short guide on overall project Structure and setting up the system and environment dependencies required for the application to run.

app/db.py contains all database interfacing method or DAO

The API layer is implemented in the app/api directory and it contains all the Flask Blueprint

The run.py file is the application's entry point, the config.py file contains the application configurations, and the requirements.txt file contains the software dependencies for the application.

Function create_app in the app/__init__.py, given a configuration name, loads the correct configuration from the config.py file, as well as the configurations from the instance/config.py file.

1. Download the latest version of Python from Python official website

2. Fork the project, clone your fork, and configure the remotes:

   # Clone your fork of the repo into the current directory
   git clone https://github.com/<your-username>/TPO-Backend-App.git
   # Navigate to the newly cloned directory
   cd TPO-Backend-App
   # Assign the original repo to a remote called "upstream"
   git remote add upstream https://github.com/aissmstpo/TPO-Backend-App.git
   

3. If you cloned a while ago, get the latest changes from upstream:

   git checkout master
   git pull upstream master
   
   # to push these changes to your fork
   git push origin master
   

4. Create the virtual environment for application:

   # navigate to the TPO-Backend-App
   cd TPO-Backend-App
   
   # create the virtual environment
   python -m venv tpo_venv
   
   # activate the virtual environment
   # for unix
   source tpo_venv/bin/activate
   
   # for Windows
   tpo_venv\Scripts\activate
   
   # install the dependencies
   pip install -r requirements.txt
   

4. Create a new topic branch (off the main project development branch) to contain your feature, change, or fix:

   git checkout -b <topic-branch-name>
   

5. Commit your changes

6. Push your topic branch up to your fork:

   git push origin <topic-branch-name>
   

7. Open a Pull Request with a clear title and description.

8. After your Pull Request is away, you might want to get yourself back onto master and delete the topic branch:

   git checkout master
   git branch -D <topic-branch-name>
