A better approach is to declare a name for your app in urls.py and then refer to that instead of hard coding anything:

in urls.py:

app_name = 'my_app'

urlpatterns = [
    path('blogs/', blog.views.blog_detail, name='mymodel_detail'),
    ]

and in models.py:

from django.urls import reverse


class BlogPost(models.Model):
    name = modelsCharField()
    slug = models.SlugField(...)

    def get_absolute_url(self):
        return ('my_app:mymodel_detail, args=[self.slug,])
