Blog Post APIs with Django Channels

This project entails the acquisition of real-time data through Django Channels, utilizing Redis and Django REST Framework for efficient implementation.

The utilization of the djangochannelsrestframework library was instrumental in shaping the project's framework. Leveraging its features, we seamlessly implemented a real-time, RESTful API infrastructure using Django Channels.

Redis is an essential component of our project, ensuring unparalleled efficiency and speed by enabling lightning-fast data retrieval, seamless message brokering and cache management.

Setup

The first thing to do is to clone the repository:

git clone https://--------------------
cd test_djangoChannels

Create a virtual environment to install dependencies in and activate it:

# Creating virtual environment
python -m venv venv

# In cmd.exe
venv\Scripts\activate.bat

Then install the dependencies:

(venv)$ pip install -r requirements.txt

Note the (venv) in front of the prompt. This indicates that this terminal session operates in a virtual environment set up by venv.

Once pip has finished downloading the dependencies.

Default it will connect sqlite3 database. For connecting Postgresql

* Open settings.py in test_oauth2 folder

Remove :

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    }
}

Add:

DATABASES = {
    'default': {
        'ENGINE': 'django_tenants.postgresql_backend',
        'NAME': '<Database Name>',
        'USER': '<postgres username>',
        'PASSWORD': '<postgres password>',
        'HOST': '<postgres host address>',
        'PORT': <postgres port>
    }
}

Provide or change the redis configuration:

CHANNEL_LAYERS = {
    "default": {
        "BACKEND": "channels_redis.core.RedisChannelLayer",
        "CONFIG": {
            "hosts": [(<Host>, <Port>)],
        },
    },
}

Run this commands in CMD:

(venv)$ python manage.py makemigrations
(venv)$ python manage.py migrate
(venv)$ python manage.py createsuperuser
Username (leave blank to use '---'): <Enter username>
Email address:<Enter email address>
