How to display data from the database in Modal (Bootstrap)?

Question

HTML

Used by Flask and Bootstrap.
Is it necessary that when clicking on a link on the page, a Modal is displayed with information that was previously requested from the database (that is, from a Python function)?
By what means is it possible to implement a request from a page and receive data from a python script? Interested in the section between the Python function and HTML?

Answer 1

Insert content when generating the main page, or AJAX request to your server when opening a modal window

Answer 2

• When opening a modal window, draw loading on the form (so that the user knows that data is being loaded).
• Then send a request to your backend with parameters.
  There are several options for sending data.
  You can use $('#div').load() or $.post or $.ajax
