Flask blueprint subdomain?

Question

Python

There are two modules for the site itself and for the admin panel. One opens on www.site.ru , the other on admin.site.ru.

main = Blueprint('main', __name__, subdomain='www')
admin = Blueprint('admin', __name__, subdomain='admin')

I want to add a third module that will work as a product catalog, each company on its own subdomain,
for example: hp.site.com or ibm.site.ru. The template is the same, but the bases are different.
Actually, how to configure this module so that it opens on different subdomains? Even better, if not www or admin, then he.

Answer 1

Found the answer:

sub = Blueprint('sub', __name__, subdomain='<trademark>')
@sub.url_defaults
def add_trademark(endpoint, values):
    values.setdefault('trademark', g.a_trademark)
@sub.url_value_preprocessor
def pull_trademark(endpoint, values):
    g.a_trademark = values.pop('trademark')
    query = City.query.filter(Company.url==g.a_trademark)
    g.trademark = query.first_or_404()
