在Django中使用sitemap的正常方法是:
from django.contrib.sitemaps import Sitemap
from schools.models import School
class SchoolSitemap(Sitemap):
changefreq = "weekly"
priority = 0.6
def items(self):
return School.objects.filter(status = 2)
然后在学校模型中我们定义:
def get_absolute_url(self):
return reverse('schools:school_about', kwargs={'school_id': self.pk})
在这种实现中,我在sitemap.xml中有一个关于一所学校的关于链接
问题是我的学校有多个页面:关于,教师,学生和其他人,我希望所有要呈现的是sitemap.xml
这样做的最佳方法是什么?

您可以使用items
may return anything that can be passed to the other methods of a Sitemap
:
import itertools
class SchoolSitemap(Sitemap):
# List method names from your objects that return the absolute URLs here
FIELDS = ("get_absolute_url", "get_about_url", "get_teachers_url")
changefreq = "weekly"
priority = 0.6
def items(self):
# This will return you all possible ("method_name", object) tuples instead of the
# objects from the query set. The documentation says that this should be a list
# rather than an iterator, hence the list() wrapper.
return list(itertools.product(SchoolSitemap.FIELDS,
School.objects.filter(status = 2)))
def location(self, item):
# Call method_name on the object and return its output
return getattr(item[1], item[0])()
如果字段的数量和名称没有预先确定,我会采用一种完全动态的方法:允许模型使用get_sitemap_urls
方法返回绝对URL列表,并使用Sitemap
执行此方法。也就是说,在最简单的情况下,您不需要访问priority / changefreq / lastmod方法中的对象:
class SchoolSitemap(Sitemap):
changefreq = "weekly"
priority = 0.6
def items(self):
return list(
itertools.chain.from_iterable(( object.get_sitemap_urls()
for object in
School.objects.filter(status = 2)))
)
def location(self, item):
return item
