Working Environment:
Framework: Python Django 1.9 OS: Ubuntu 16.04 ( Linux ) Database: MySql
1 Configuration (settings.py):
There are a few things that I added in the settings.py file for the project to work:
INSTALLED_APPS = ( 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'Channels', # for the chatting application to work and below I also added layers 'Bootstrap3', # 'Social.membership', # application membership 'Social.chat', # application chat ) BOOTSTRAP3 = { 'jquery_url': '//code.jquery.com/jquery.min.js', 'base_url': '//maxcdn.bootstrapcdn.com/bootstrap/3.3.7/', }
redis_host = os.environ.get('REDIS_HOST', 'localhost') # redis host
CHANNEL_LAYERS = { "default": { "BACKEND": "asgi_redis.RedisChannelLayer", "CONFIG": { "hosts": [os.environ.get('REDIS_URL', 'redis://localhost:6379')], }, "ROUTING": "social.chat.routing.channel_routing", }, }
DATABASES = { 'default': { 'ENGINE':'django.db.backends.mysql', 'NAME': 'social', 'USER':'myproject', 'PASSWORD':'p@ssword', 'HOST':'localhost', 'PORT': '', } }
2 Grouping Application Requirements: Anyone can create a group and become the group owner; 2) Group owner can set the group name and description; 3) Group owner should be able to choose “on my approval” for invitations send by the members [invitations must be approved by owner before sending out]; 4) Anyone can invite others to the group by sending an invitation, and the invitation must be approved by the owner if “on my approval” is chosen; 5) An invited member must acknowledge the invitation to join the group
2.1 Django Registration: I used predefined package Django-Registration 2.2 to achieve the functionalities of user registration, login, logout, password reset, etc. For the installation of django-registration 2.2, refer to the web page https://django-registration.readthedocs.io/en/2.2/install.html
Please note that django-registration 2.2 does not work in Django 1.11
- Chat Application Requirements:
- Anyone can chat within a group
- Can @mention someone
3.1 Django Channels I used Django channels module to achieve real time messaging, passing SocialGroup name to window.location.path (client side javascript), and to retrieve SocialGroup name when websocket.connect, then create a chat room for the SocialGroup (in server side consumers.py).
For the installation of Django channels, refer to web page http://channels.readthedocs.io/en/stable/index.html
