I created a list of the posts I want to display. How would I go about paginating a list of posts? If you need code I can give it, but I just need an example of taking a list of posts, messages, etc. and paginating them. Thanks in advance!

On the server have a list,send list to html template.
In html template loop over list with jinja. server: from flask import Flask, render_template, jsonify
app = Flask(__name__)
@app.route('/')
def bar():
lst = ["Python", 'HTML', 'JavaScript']
return render_template("index_page.html", lst=lst)
if __name__ == '__main__':
app.run(debug=True)index_page.html:<!doctype html>
<html>
<head>
<link rel=stylesheet type=text/css href="{{ url_for('static', filename='css/style.css') }}" />
</head>
<body>
<p>Navigation pagination:</p>
<div class="pagination">
<ul>
<a href="#" class="active">Home</a>
{% for page in lst %}
<a href="#">{{ page }}</a>
{% endfor %}
</ul>
</div>
</body>
</html>

Not what I was looking for but totally my fault for the lack of communication.
posts = []
for following in current_user.followingList:
post = Post.query.filter_by(username=following).first()
if post:
posts.append(post)
posts = Post.query.order_by(order).paginate(parameters) #This will give me all the posts but I only want to use the posts from the list
