Project Goals

Authenticated users can:
- Access a GraphQL endpoint and run several Quries and CRUD Mutations.
- Access a Rest API endpoint and run CRUD operations.
- Create, Read, Update and Delete (CRUD) blog posts on the website.
- Add comments on blog posts, but the comments will not be visiable until the website admin approves it.
- Like Blog posts and Add them to their favorite list (using HTMX).
- Access their profile which lists all their blog posts and their favorite posts.
All users can read or search for the posts on the blog.
Users can access separate frontend project built using Vue.js 3, Tanstack-Vue-Query, Vue-Apollo and Quasar Framework which connects with django through Django Rest Framework using Session Authentication.
The frontend vue.js app also allows users to perform CRUD operations through connecting to a REST API and a GraphQL endpoints.

Currently in Vue frontend users can:

Register for an account and log in to their account (users will be authenticated using Django Rest Framework Session Authentication).
Add tags to blog using a Rest API endpoint and GraphQL endpoint.
Perform CRUD operations to blog posts using both REST API and GraphQL.
Perform CRUD operations to add comments to blog posts using both REST API and GraphQL.
Add and remove posts to and form their favorite posts list.
Access pages that show their added blog posts and their favorite posts.
Search for blog posts by title and limiting the results using both REST API and GraphQL

To get started with this project without Docker:

Make sure that both PostgreSQL database and Mailpit Email client are installed and running in your system.
Create a PostgreSQL database, This project uses PostgreSQL version 14.
Export database default url using the following terminal command, In this example PostgreSQL is installed locally, database name is django-blog-backend, and database admin credentials are => username: admin / password: 1234:

export DATABASE_URL=postgres://admin:[email protected]:5432/django-blog-backend

Open the terminal or CMD to create a virtual environment like Python virtual environment (venv) or pipenv and activate it.
- python -m venv venv Create the venv
- source venv/bin/activate On Linux
- venv/Scripts/activate On Windows
- source venv/Scripts/activate Git Bash on Windows
Change directory to django_blog_backend cd django_blog_backend
Install local.txt requirements file: python -m pip install -r requirements/local.txt
Create the database by running the following commands: python manage.py makemigrations python manage.py migrate
Create a super user: python manage.py createsuperuser
Run the project: python manage.py runserver
Before logging in to the Django website make sure that Mailpit email client is running in your system to recieve an email activation link.

To get started with this project with Docker:

Make sure that Docker and docker-compose are installed in your system.
Clone the repository: git clone https://github.com/MoustafaShaaban/Advanced_Django_Blog.git
Change directory to blog_backend directory cd blog_backend
Build the docker image to develop the project locally using docker-compose:

docker-compose -f local.yml build

Create the database by running the following commands:

docker-compose -f local.yml run --rm django python manage.py migrate

Create a super user:

docker-compose -f local.yml run --rm django python manage.py createsuperuser

Run the test using pytest:

docker compose -f local.yml run --rm django test blog_backend/blog

Now run the project:

docker-compose -f local.yml up

Open the web browser and go to http://localhost:8000/ to see the results.
Start a new terminal and change directory to vue-frontend directory and install the requirements:
