Django项目之图书管理系统

以下是一个简化的Django图书管理系统的代码实例，展示了如何创建一个图书模型并添加基本的视图函数。



# models.py
from django.db import models
 
class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.CharField(max_length=100)
    published_date = models.DateField()
    isbn = models.CharField(max_length=13)
 
    def __str__(self):
        return self.title
 
# views.py
from django.shortcuts import render
from django.http import HttpResponse
from .models import Book
 
def book_list(request):
    books = Book.objects.all()
    return render(request, 'books.html', {'books': books})
 
def book_create(request):
    if request.method == 'POST':
        title = request.POST.get('title')
        author = request.POST.get('author')
        published_date = request.POST.get('published_date')
        isbn = request.POST.get('isbn')
 
        new_book = Book.objects.create(
            title=title,
            author=author,
            published_date=published_date,
            isbn=isbn
        )
 
        return HttpResponse(f"Book created: {new_book}")
 
    return render(request, 'create_book.html')
 
# urls.py
from django.urls import path
from .views import book_list, book_create
 
urlpatterns = [
    path('', book_list, name='book_list'),
    path('create/', book_create, name='book_create'),
]
 
# books.html (简单的HTML表格展示图书列表)
<!DOCTYPE html>
<html>
<head>
    <title>Book List</title>
</head>
<body>
    <h1>Book List</h1>
    <ul>
        {% for book in books %}
        <li>{{ book.title }} by {{ book.author }}</li>
        {% endfor %}
    </ul>
</body>
</html>
 
# create_book.html (简单的HTML表单用于创建新图书)
<!DOCTYPE html>
<html>
<head>
    <title>Create Book</title>
</head>
<body>
    <h1>Add New Book</h1>
    <form method="post" action="">
        <label for="title">Title:</label>
        <input type="text" id="title" name="title"><br><br>
        <label for="author">Author:</label>
        <input type="text" id="author" name="author"><br><br>
        <label for="published_date">Published Date:</label>
        <input type="date" id="published_date" name="published_date"><br><br>
        <label for="isbn">ISBN
