我的网站地图页面上的django项目出现'str' object has no attribute 'get_absolute_url'错误。任何帮助表示赞赏。
这是我的追溯：

我的sitemaps.py文件
from django.contrib import sitemaps
from django.contrib.sitemaps import Sitemap
from django.urls import reverse
from deals.models import Deal
from blog.models import Post
class StaticViewSitemap(sitemaps.Sitemap):
priority = 1.0
changefreq = 'daily'
def items(self):
return ['about', 'contact', 'disclosure', 'terms', 'privacy', 'deals:deals', 'blog:blog']
class BlogSitemap(Sitemap):
changfreq = "daily"
priority = 1.0
location ='/blog'
def items(self):
return Post.objects.filter(status='Published')
def lastmod(self, obj):
return obj.created
class DealSitemap(Sitemap):
changfreq = "daily"
priority = 1.0
def items(self):
return Deal.objects.all()
def lastmod(self, obj):
return obj.date_added
和我的两个相关模型（Deal和Post），我创建了一个get_absolute_url方法，因为它之前在站点地图上生成了错误：
class Deal(models.Model):
title = models.CharField(max_length=200)
slug = models.SlugField(max_length=140, unique=True)
description = RichTextUploadingField(default='')
retailer = models.ForeignKey(Retailer, on_delete=models.CASCADE)
image = VersatileImageField('deal image',
upload_to=deal_upload_path,
null=True,
blank=True)
link = models.URLField(max_length=2000, default='')
category = models.ForeignKey(Category, on_delete=models.CASCADE)
date_added = models.DateField(default=timezone.now)
date_expires = models.DateField(default=timezone.now)
price = models.CharField(max_length=140)
secondary_price = models.CharField(max_length=140, default='')
likes_total = models.IntegerField(default=1)
expired = models.BooleanField(default=False)
def __str__(self):
return "@{} ({})".format(self.title, self.retailer)
def _get_unique_slug(self):
slug = slugify(self.title)
unique_slug = slug
num = 1
while Deal.objects.filter(slug=unique_slug).exists():
unique_slug = '{}-{}'.format(slug, num)
num += 1
return unique_slug
def save(self, *args, **kwargs):
if not self.slug:
self.slug = self._get_unique_slug()
super().save()
def get_label(self):
if self.date_added > datetime.date.today() - datetime.timedelta(days=4):
return "<span class='"'notify-badge'"'>new</span>"
else:
return ''
def get_absolute_url(self):
return reverse('deals:deal_detail', kwargs={'slug': self.slug})
class Post(models.Model):
STATUS_CHOICES = (
('Published', 'Published'),
('Draft', 'Draft'),
)
title = models.CharField(max_length=100, unique=True)
body = RichTextUploadingField()
category = models.ForeignKey(BlogCategory, on_delete=models.CASCADE)
seo_title = models.CharField(max_length=60, blank=True, null=True)
seo_description = models.CharField(max_length=165, blank=True, null=True)
slug = models.SlugField(max_length=200, unique=True)
image = VersatileImageField('blog image',
upload_to='media/blog_images',
null=True,
blank=True)
created = models.DateTimeField(db_index=True, auto_now_add=True)
updated = models.DateTimeField(auto_now=True)
status = models.CharField(max_length=10, default='Draft', choices=STATUS_CHOICES)
def get_absolute_url(self):
return reverse('blog:blog_post', kwargs={'slug': self.slug})
def save(self, *args, **kwargs):
self.slug = slugify(self.title)
super(Post, self).save(*args, **kwargs)
def __str__(self):
return self.title
和我的urls.py文件及相关信息
from django.contrib.sitemaps.views import sitemap
sitemaps = {
'static': StaticViewSitemap,
'blog': BlogSitemap,
'deals': DealSitemap
}
path('sitemap.xml', sitemap,
{'sitemaps': sitemaps},
name='django.contrib.sitemaps.views.sitemap'),
答案 0 :(得分：3)
您没有正确地关注example的StaticViewSitemap。正如文档所说，从items()返回的元素将传递给location()方法;由于项通常是模型实例，因此此方法的默认实现是调用每个实例的get_absolute_url()方法。在您的情况下，您正在传递URL名称，因此您需要适当地重新定义location() - 再次如示例所示。
def location(self, item):
return reverse(item)
答案 1 :(得分：0)
请求location()方法的是get_absolute_url()函数：here。如果您绝对确定您的字符串已经是 absolute path，您可以通过以下方式在类中简单地覆盖它：
def location(self, item) :
return item
这将返回您已经设置的绝对路径。
