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) is just fetch dynamically posts from database. You can put your logic to fetch dynamically content. Ask from chatgpt for better help.
