'snake', ] And at the end add: import os STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') ________________________________________ Step 2: Frontend Implementation 2.1 Create the Template Inside the snake app, create a folder structure for templates and static files: snake/ ├── templates/ │ └── snake/ │ └── game.html ├── static/ └── snake/ ├── css/ │ └── style.css └── js/ └── game.js Create game.html: {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Hungry Snake Game</title> <link rel="stylesheet" href="{% static 'snake/css/style.css' %}"> </head> <body> <div class="game-container"> <canvas id="gameCanvas" width="500" height="500"></canvas> </div> <script src="{% static 'snake/js/game.js' %}"></script> </body> </html> 2.2 Add CSS Styles Create static/snake/css/style.css to style the game: body { margin: 0; display: flex; justify-content: center; align-items: center; height: 100vh; background-color: #1d3557; } .game-container { position: relative; width: 500px; height: 500px; border: 2px solid #457b9d; background-color: #a8dadc; } 2.3 Add JavaScript Create static/snake/js/game.js for game logic: const canvas = document.getElementById("gameCanvas"); const ctx = canvas.getContext("2d"); const tileSize = 20; const canvasSize = 500; let snake = [{ x: 240, y: 240 }]; let food = getRandomFoodPosition(); let direction = { x: 0, y: -tileSize }; function draw() { ctx.fillStyle = "#1d3557"; ctx.fillRect(0, 0, canvasSize, canvasSize); // Draw the snake ctx.fillStyle = "#e63946"; snake.forEach(segment => { ctx.fillRect(segment.x, segment.y, tileSize, tileSize); }); // Draw the food ctx.fillStyle = "#f1faee"; ctx.fillRect(food.x, food.y, tileSize, tileSize); } function update() { const head = { x: snake[0].x + direction.x, y: snake[0].y + direction.y }; // Check collision with walls if (head.x < 0 || head.x >= canvasSize || head.y < 0 || head.y >= canvasSize) { resetGame(); return; } // Check collision with self if (snake.some(segment => segment.x === head.x && segment.y === head.y)) { resetGame(); return; } snake.unshift(head); if (head.x === food.x && head.y === food.y) { food = getRandomFoodPosition(); } else { snake.pop(); } } function getRandomFoodPosition() { return { x: Math.floor(Math.random() * (canvasSize / tileSize)) * tileSize, y: Math.floor(Math.random() * (canvasSize / tileSize)) * tileSize }; } function resetGame() { snake = [{ x: 240, y: 240 }]; direction = { x: 0, y: -tileSize }; food = getRandomFoodPosition(); } function changeDirection(event) { const keyMap = { ArrowUp: { x: 0, y: -tileSize }, ArrowDown: { x: 0, y: tileSize }, ArrowLeft: { x: -tileSize, y: 0 }, ArrowRight: { x: tileSize, y: 0 } }; const newDirection = keyMap[event.key]; if (newDirection && (newDirection.x !== -direction.x || newDirection.y !== -direction.y)) { direction = newDirection; } } document.addEventListener("keydown", changeDirection); function gameLoop() { update(); draw(); setTimeout(gameLoop, 150); } gameLoop(); ________________________________________ Step 3: Backend Implementation 3.1 Create a View Edit snake/views.py to render the game: from django.shortcuts import render def game(request): return render(request, 'snake/game.html') 3.2 Add URLs Create snake/urls.py: from django.urls import path from . import views urlpatterns = [ path('', views.game, name='game'), ] Update snake_game/urls.py to include the app’s URLs: from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('', include('snake.urls')), ] ________________________________________ Step 4: Run the Server 4.1 Collect Static Files python manage.py collectstatic 4.2 Start the Server Run the development server: python manage.py runserver Access your game at 127.0.0.1:8000/.

Step 1: Define a ListView in views.py Create a view to display the list of questions: from django.views.generic import ListView from .models import Question class QuestionListView(ListView): model = Question # Model to display template_name = 'polls/question_list.html' # HTML file to use context_object_name = 'questions' # Variable name for template ________________________________________ Step 2: Create the Template Create a new HTML file at polls/templates/polls/question_list.html: <h1>Poll Questions</h1> <ul> {% for question in questions %} <li>{{ question.question_text }}</li> {% endfor %} </ul> ________________________________________ Step 3: Add the URL in urls.py Add the view to the URL configuration in polls/urls.py: from django.urls import path from .views import QuestionListView urlpatterns = [ path('questions/', QuestionListView.as_view(), name='question-list'), ] ________________________________________ Step 4: View the List in Browser Run the Django server and visit: 127.0.0.1:8000/polls/questions/ ________________________________________ 4. Displaying a Single Question Using DetailView Step 1: Define a DetailView in views.py from django.views.generic import DetailView from .models import Question class QuestionDetailView(DetailView): model = Question template_name = 'polls/question_detail.html' context_object_name = 'question' ________________________________________ Step 2: Create the Template Create a new file at polls/templates/polls/question_detail.html: <h1>{{ question.question_text }}</h1> <p>Published on: {{ question.pub_date }}</p> ________________________________________ Step 3: Add the URL in urls.py from django.urls import path from .views import QuestionDetailView urlpatterns += [ path('questions/<int:pk>/', QuestionDetailView.as_view(), name='question-detail'), ] ________________________________________ Step 4: View the Details in Browser Visit: 127.0.0.1:8000/polls/questions/1/ ________________________________________

________________________________________ 2. Writing the Templates a. index.html (Home Page) {% if latest_question_list %} <ul> {% for question in latest_question_list %} <li><a href="{% url 'detail' question.id %}">{{ question.question_text }}</a></li> {% endfor %} </ul> {% else %} <p>No polls are available.</p> {% endif %} <h2>Latest Questions:</h2> {% for question in latest_question_list %} <p>{{ question.question_text }}</p> {% empty %} <p>No questions available.</p> {% endfor %} b. detail.html (Question Details Page) <h1>{{ question.question_text }}</h1> <ul> {% for choice in question.choice_set.all %} <li>{{ choice.choice_text }}</li> {% endfor %} </ul> ________________________________________ 3. Updating Views to Use Templates from django.shortcuts import get_object_or_404, render from .models import Question def index(request): latest_question_list = Question.objects.order_by('-pub_date')[:5] return render(request, 'polls/index.html', {'latest_question_list': latest_question_list}) def detail(request, question_id): question = get_object_or_404(Question, pk=question_id) return render(request, 'polls/detail.html', {'question': question}) def results(request, question_id): question = get_object_or_404(Question, pk=question_id) return render(request, 'polls/results.html', {'question': question}) def vote(request, question_id): question = get_object_or_404(Question, pk=question_id) # Try to get the selected choice, handle errors if no choice is selected selected_choice = question.choice_set.filter(pk=request.POST.get('choice')).first() if not selected_choice: return render(request, 'polls/detail.html', { 'question': question, 'error_message': "You didn't select a choice." }) # Increment vote and save selected_choice.votes += 1 selected_choice.save() return redirect('polls:results', question_id=question.id) ________________________________________ ________________________________________ 1. Start the Django development server: python manage.py runserver 2. Open your web browser and visit: o 127.0.0.1:8000/polls/ → to see the index page

1. Define Views in polls/views.py Open the polls/views.py file and add the following functions: from django.http import HttpResponse from .models import Question def index(request): latest_question_list = Question.objects.order_by('-pub_date')[:5] output = ', '.join([q.question_text for q in latest_question_list]) return HttpResponse(output) def detail(request, question_id): return HttpResponse(f"You're looking at question {question_id}.") def results(request, question_id): return HttpResponse(f"You're looking at the results of question {question_id}.") def vote(request, question_id): return HttpResponse(f"You're voting on question {question_id}.") ________________________________________ 2. Link Views to URLs in polls/urls.py Open the polls/urls.py file and add the following code: from django.urls import path from . import views urlpatterns = [ path('', views.index, name='index'), path('<int:question_id>/', views.detail, name='detail'), path('<int:question_id>/results/', views.results, name='results'), path('<int:question_id>/vote/', views.vote, name='vote'), ] ________________________________________ Step 3: Testing the Views 1. Start the Django development server: python manage.py runserver 2. Open your browser and visit the following URLs: o localhost:8000/polls/ → Opens the index view. o localhost:8000/polls/1/ → Opens the detail view for question 1. o localhost:8000/polls/1/results/ → Opens the results view for question 1. o localhost:8000/polls/1/vote/ → Opens the vote view for question 1. ________________________________________

Step 1: Creating a Superuser 1. Open your terminal and run: python manage.py createsuperuser 2. Enter the required details when prompted: o Username: Azad o Email: azad977@gmail.com o Password: (Choose a strong password) Once done, you will see: "Superuser created successfully." ________________________________________ Step 2: Accessing the Admin Interface 1. Start the Django development server: python manage.py runserver 2. Open the admin page in your browser: o Go to: 127.0.0.1:8000/admin o Enter your superuser username and password to log in. 1. Open the admin.py file in your app folder (e.g., polls): 2. Add the following code to register the Question model: from django.contrib import admin from .models import Question admin.site.register(Question) ________________________________________

Steps to Define Models 1. Open the polls/models.py file. 2. Add the following code: from django.db import models class Question(models.Model): question_text = models.CharField(max_length=200) # Question text pub_date = models.DateTimeField('date published') # Date and time of publication class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) # Links to Question choice_text = models.CharField(max_length=200) # Choice text votes = models.IntegerField(default=0) # Vote count ________________________________________ Steps to Create Migrations • Open the terminal and run: python manage.py makemigrations polls • Apply the migrations to update the database: python manage.py migrate ________________________________________ Steps to Add Methods 1. Open polls/models.py and update the models: import datetime from django.db import models from django.utils import timezone class Question(models.Model): question_text = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') def __str__(self): return self.question_text def was_published_recently(self): now = timezone.now() return now - datetime.timedelta(days=1) <= self.pub_date <= now was_published_recently.admin_order_field = 'pub_date' was_published_recently.boolean = True was_published_recently.short_description = 'Published recently?' class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) votes = models.IntegerField(default=0) def __str__(self): return self.choice_text Steps to Apply Changes 1. Run: python manage.py makemigrations polls 2. Apply the migrations: python manage.py migrate ________________________________________ Steps to Register Models 1. Open polls/admin.py and add: from django.contrib import admin from .models import Question, Choice class QuestionAdmin(admin.ModelAdmin): list_display = ('question_text', 'pub_date', 'was_published_recently') admin.site.register(Question, QuestionAdmin) admin.site.register(Choice) ________________________________________ Steps to Test 1. Run the development server: python manage.py runserver 2. Open your web browser and go to the Django admin panel at: 127.0.0.1:8000/admin/ ________________________________________
