Make route as a shortcut for as_view() method when you don't need to pass class arguments:

from flask.views import MethodView

@app.route('/users/', endpoint='users')
class UserAPI(MethodView):

    def get(self):
        users = User.query.all()
        ...

    def post(self):
        user = User.from_form_data(request.form)
        ...

Or

from flask.views import View

@app.route('/users/', endpoint='show_users')
class ShowUsers(View):

    def dispatch_request(self):
        users = User.query.all()
        return render_template('users.html', objects=users)
