- Python3
- Django3
- DRF (Django Rest Framework) - getting actual info by using REST (in this project by AJAX on frontend)
- Django Channels - websocket connection for bid system and chat
- Celery - automatic listing's completion by task with countdown
- Docker - project deploying (dev and prod deploying versions)
Name, Category, Start Price. Image and Description are optional.
When listing is created, Celery task is starting with countdown for created listing, countdown depends on the number of hours that was selected in the last field on Creation page.
Celery task:
DjangoAuctionApp/market/tasks.py
Line 14 in 0666b2d
Task starting with new listing creation:
DjangoAuctionApp/market/views.py
Line 136 in 0666b2d
new_listing = AuctionListing.objects.create(name = name, description = description,loaded_image=image_file,image = image, category = category, user = user, startBid = startBid, creationDate = current_date, endDate = end_date, active = active)
new_listing.save()
seconds_to_end = int(datetime.timedelta.total_seconds(new_listing.endDate - new_listing.creationDate))
task = create_task.apply_async(kwargs = {"listing_id": new_listing.id}, countdown = seconds_to_end)
Name, image, price, last bid, time to end (JS live timer) and Owner
Websocket connection automatically opens with anyone, who entered on this page. (separed connection groups for each listing). Websocket connection makes "live" bid system and comments.
DjangoAuctionApp/market/consumers.py
Line 22 in f8f6784
class ListingConsumer(WebsocketConsumer):
def connect(self):
self.user = self.scope['user']
self.room_name = self.scope['url_route']['kwargs']['listing_id']
self.room_group_name = 'market_%s' % self.room_name
#Join room group by listing url
async_to_sync(self.channel_layer.group_add)(
self.room_group_name,
self.channel_name
)
self.accept()
Websocket connection for chat system is active on every page and only for Authorized user's.
Every Authorized user connects to websocket on Chat Consumer and have it's own "connection group" with himself only. It's safety, cause only target user will get websocket message on his client and there are still posible to show new messages count in 'live' with Inbox NavBar menu
DjangoAuctionApp/market/consumers.py
Line 222 in f8f6784
class ChatConsumer(WebsocketConsumer):
def connect(self):
self.user = self.scope['user']
if self.user.is_active == True and self.user.is_anonymous == False:
self.room_group_name = f'chat_{self.user.id}'
# Join room group
async_to_sync(self.channel_layer.group_add)(
self.room_group_name,
self.channel_name
)
self.accept()
else:
self.close()
There are also opportunity to change user's Avatar. Using template Django form and Pillow allow to save media files in safety way. (To make sure that is really media files)

-
Build the images and run the containers:
$ docker-compose up -d --build
-
Don't forget to create superuser (needs to get access to admin panel)
$ docker-compose exec web python3 manage.py createsuperuser
Test it out at http://localhost:8000(http://127.0.0.1:8000).
Uses daphne + nginx.-
Rename .env.prod-sample to .env.prod and .env.prod.db-sample to .env.prod.db. Update the environment variables as you need.
