[Yash Garg]

When i'm loading sitemap.xml for my site i'm getting this error

Reverse for 'blog-detail' with arguments '('This is my title slug', '2020', '2', '19')' not found. 1 pattern(s) tried: ['blog\\/(?P<year>[0-9]+)\\/(?P<month>[0-9]+)\\/(?P<day>[0-9]+)\\/(?P<slug>[-a-zA-Z0-9_]+)$']

sitemap.py 

class BlogSitemap(Sitemap):
    priority = 0.5
    changefreq = 'daily'

    def  items(self):
        return Blog.objects.filter(status=1)
    
    def location(self, item):
        return reverse('blog-detail', args = (item.slug, str(item.blog_published_at.year), str(item.blog_published_at.month), str(item.blog_published_at.day)))

Models.py
class Blog(models.Model):

    STATUS = (
        (0,"Draft"),
        (1,"Publish")
    )

    blog_title = models.CharField(_("Blog Title For Slug"), validators=[MinLengthValidator(8)], max_length=120, blank=False,null=False)
    title = models.CharField(_("Blog Title"), validators=[MinLengthValidator(8)], max_length=120, blank=True,null=False)
    slug = models.SlugField(_("Slug"), max_length=200, unique = True, blank = True)
    meta_tag = models.TextField(_("Blog Meta tags"), null = False, blank= True)
    banner_text = models.CharField(_("Top Banner Text Overlay"), max_length = 50, null = False)
    banner_image = models.FileField(_("Banner Image"), blank=True)
    blog_abstract = models.TextField(_("Blog Abstract"), max_length= 500, blank = False, null = False)
    blog_published_at = models.DateField(_("Blog published date") , blank = False, default = timezone.now)
    blog_image = models.FileField(_("Blog Image"), blank=True)
    def __str__(self):
        return self.title

    class Meta:
        ordering = ['-blog_published_at']
        db_table = '"public_blog"'

    def get_absolute_url(self):
        return reverse('blog-detail', args=(self.slug, self.blog_published_at.year, self.blog_published_at.month, self.blog_published_at.day))

    def save(self):
        super(Blog, self).save()
        self.slug = slugify(self.blog_title)
        super(Blog, self).save()
urls.py 

path('sitemap.xml', sitemap, {'sitemaps':sitemaps}, name = 'sitemap'),

Thank You

You are using positional arguments when you should be using named args.  Change the line to

return reverse('blog-detail', kwargs = {‘slug’:item.slug, ‘year’:str(item.blog_published_at.year), ‘month’:str(item.blog_published_at.month), ‘day’:str(item.blog_published_at.day)})
