thank you!

Thanks

thanks

thank you :)

great!

Appreciate it

really helpful, thanks

Thank you !!!

thanks !

thanks, this seems to be best solution so far.
I just made a slight change to hide private endpoints, 'startswith' can also take a tuple of values which makes adding multiple endpoints quite easy...

private_endpoints = ("/admin", "/user", "/foo", "/bar")

...

# Static routes with static content
static_urls = list()
for rule in app.url_map.iter_rules():
    if not str(rule).startswith(private_endpoints):
        if "GET" in rule.methods and len(rule.arguments) == 0:
            url = {
                "loc": f"{host_base}{str(rule)}"
            }
            static_urls.append(url)

Hi! I am trying to use this but I dont understand how to use or modify line 29. Where is the Post object coming from and how can I generalize this to other blueprints pr dynamic sections of a flask site?

    blog_posts = Post.objects(published=True)

    blog_posts = Post.objects(published=True)

blog_posts = Post.objects(published=True) is just fetch dynamically posts from database. You can put your logic to fetch dynamically content. Ask from chatgpt for better help.
