For reference only:
Define model: Define a model to store information in board and card games, such as users, game records, game states, etc.
Create views: Use Django's views to process user requests and retrieve game data from the database.
Create templates: Use HTML and CSS to create templates to display game content, including the game board, game state, etc.
Add user authentication: Use Django's user authentication system to enable user login and registration.
Realize the game logic: write the logic code of chess and card games, such as the rules of the game, chess logic, victory and defeat judgment.
Play line: Use Djangos WebSocket library to play online.
Here is a simple Django online chess room tutorial:
Creating Django projects and applications:
$ django-admin startproject chessroom
$ cd chessroom
$ python manage.py startapp game
Define model:
from django.db import models
from django.contrib.auth.models import User
class Game(models.Model):
player1 = models.ForeignKey(User, on_delete=models.CASCADE, related_name='player1')
player2 = models.ForeignKey(User, on_delete=models.CASCADE, related_name='player2')
game_state = models.TextField()
Create a view:
from django.shortcuts import render
from django.http import HttpResponse
def game_view(request):
game = Game.objects.get(id=1)
return render(request, 'game.html', {'game': game})
Create a template:
html>
<html>
<head>
<title>Chess Roomtitle>
head>
<body>
<div>
<h1>Chess Roomh1>
<p>Welcome, {{ user.username }}!p>
<div>{{ game.game_state }}div>
div>
body>
html>
Add user authentication:
from django.contrib.auth.decorators import login_required
@login_required
def game_view(request):
game = Game.objects.get(id=1)
return render(request, 'game.html', {'game': game})
Implement the game logic:
def make_move(request):
if request.method == 'POST':
game_id = request.POST.get('game_id')
player_id = request.POST.get('player_id')
move = request.POST.get('move')
game = Game.objects.get(id=game_id)
game_state = game.game_state
# update game state
# check for game over
# update game in database
return HttpResponse('OK')
Realize online battle:
import json
from channels.generic.websocket import WebsocketConsumer
class GameConsumer(WebsocketConsumer):
def connect(self):
self.accept()
self.game_id = self.scope['url_route']['kwargs']['game_id']
self.game_group_name = 'game_%s' % self.game_id
async_to_sync(self.channel_layer.group_add)(
self
