After writing the views, we will surely want to render the content on a template and get information from the underlying database.
To render to templates, we will use Jinja2 as the templating language. Refer to Chapter 2, Templating with Jinja2, to understand templating in depth.
We will again work in reference to our existing catalog application from the previous recipe. We will now modify our views to render templates and then display data from the database in these templates.
The following is the modified views.py code and the templates. The complete app can be downloaded from the code bundle provided with this book.
We will start by modifying our views, that is, flask_catalog_template/my_app/catalog/views.py, to render templates on specific handlers:
from flask import render_template
@catalog.route('/')
@catalog.route('/home')
def home():
return render_template('home.html')Notice the render_template() method. This method will render home...
