Django 3.0:获取get_absolute_url的错误

我得到这个错误：

在/product/1770422792449276022367789942330057699处的类型错误/ product（）获得意外的关键字参数“id”

我试图生成产品的详细页面（书就是产品）

url.py

app_name = 'bookrepo'

urlpatterns = [
    path('',views.home,name='home'),
    path('product/',views.product,name='product'),
    path('product/<id>/', views.product, name='product_detail'),
    ]

def product(request):
    return render(request, 'bookrepo/product.html')

class Book(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    title = models.CharField('Title', max_length=255)
    authors = models.ManyToManyField(Author, related_name='books_written')
    publisher = models.ForeignKey(Publisher, on_delete=models.DO_NOTHING, related_name='books_published')
    price = models.DecimalField('Price', decimal_places=2, max_digits=10)
    description = models.TextField('Description')
    upload_timestamp = models.DateTimeField('Uploading DateTime', auto_now_add=True)
    categories = models.ManyToManyField(Category, related_name='book_category')

    def get_absolute_url(self):
        return "/product/%i/" % self.id

def product(request, id=None):
    return render(request, 'bookrepo/product.html')

型号.py

app_name = 'bookrepo'

urlpatterns = [
    path('',views.home,name='home'),
    path('product/',views.product,name='product'),
    path('product/<id>/', views.product, name='product_detail'),
    ]

def product(request):
    return render(request, 'bookrepo/product.html')

class Book(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    title = models.CharField('Title', max_length=255)
    authors = models.ManyToManyField(Author, related_name='books_written')
    publisher = models.ForeignKey(Publisher, on_delete=models.DO_NOTHING, related_name='books_published')
    price = models.DecimalField('Price', decimal_places=2, max_digits=10)
    description = models.TextField('Description')
    upload_timestamp = models.DateTimeField('Uploading DateTime', auto_now_add=True)
    categories = models.ManyToManyField(Category, related_name='book_category')

    def get_absolute_url(self):
        return "/product/%i/" % self.id

def product(request, id=None):
    return render(request, 'bookrepo/product.html')

关于我的视图和URL，我可能完全错了。我想在单击模板中的按钮后显示书籍详细信息。

更改视图。py

app_name = 'bookrepo'

urlpatterns = [
    path('',views.home,name='home'),
    path('product/',views.product,name='product'),
    path('product/<id>/', views.product, name='product_detail'),
    ]

def product(request):
    return render(request, 'bookrepo/product.html')

class Book(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    title = models.CharField('Title', max_length=255)
    authors = models.ManyToManyField(Author, related_name='books_written')
    publisher = models.ForeignKey(Publisher, on_delete=models.DO_NOTHING, related_name='books_published')
    price = models.DecimalField('Price', decimal_places=2, max_digits=10)
    description = models.TextField('Description')
    upload_timestamp = models.DateTimeField('Uploading DateTime', auto_now_add=True)
    categories = models.ManyToManyField(Category, related_name='book_category')

    def get_absolute_url(self):
        return "/product/%i/" % self.id

def product(request, id=None):
    return render(request, 'bookrepo/product.html')

使用

/product/%s/%self.id

代替，

%i

将您的uuid转换为一个大的number@minglyu同样的错误：

product（）得到了一个意外的关键字参数“id”

。我认为问题出在

url.py

或视图中
