Overwrite route in flask blueprint

There are 2 solutions which I found. First:

from flask import Flask, Blueprintsimple_page = Blueprint('simple_page', __name__, )@simple_page.route('/my/route/')def my():    # for example it's a registered route somewhere...    return 'default'@simple_page.route('/my/route/')def new_my():    # new endpoint / should works instead my()    return 'new'# map of views which we won't register in Flask app# you can store this somewhere in settingsSKIP_VIEWS = (    # route, view function    ('/my/route/', my, ),)class CustomFlask(Flask):    def add_url_rule(self, rule, endpoint=None, view_func=None, **options):        # Flask registers views when an application starts        # do not add view from SKIP_VIEWS        for rule_, view_func_ in SKIP_VIEWS:  # type: str, func            if rule_ == rule and view_func == view_func_:                return        return super(CustomFlask, self).add_url_rule(rule, endpoint, view_func, **options)app = CustomFlask(__name__)app.register_blueprint(simple_page)app.run(debug=True)

Second way:

two.py - default blueprint with endpoint

from flask import Blueprintbp_two = Blueprint('simple_page2', __name__, )@bp_two.route('/my/route/')def default():    return 'default'

test.py - your blueprint + app

from flask import Flask, Blueprintfrom two import bp_twoyour_bp = Blueprint('simple_page', __name__, )@your_bp.route('/my/route/')def new_route():    return 'new'app = Flask(__name__)# register blueprint and turn off '/my/route/' endpointapp.register_blueprint(bp_two, **{'url_defaults': {'/my/route/': None}})app.register_blueprint(your_bp)app.run(debug=True)

Run app. Open /my/route/. You will see that default endpoint wasn't add/works.

Hope this helps.
