Every web framework needs a way to generate full HTML pages. In Django we use templates to serve individual HTML files.
Each app should have its own templates folder, for example, in the movie app folder, create a folder called templates/, Django will look for template files iterating over every app’s templates folder.
See [[Why we have to place template files under a sub-folder which is named after app name]]
In Django development, we will see pattern for each page: templates, views and URLs.
To create a function view and define an URL, see [[Define an URL and link it to a function view]].
Template
Create a new template file about.html in movie/templates, fill it with the following:
<!DOCTYPE html>
<html>
<head>
<title>Movies App</title>
</head>
<body>
<h1>Welcome to About Page, {{ name }}</h1>
<h2>This is the full about page</h2>
</body>
</html>
View
Back in movie/views.py, add a about view and connect it to the template about.html.
from django.shortcuts import render
def about(request):
return render(request, 'about.html', {'name': 'Jump Roper'})
The view contains the business logic or the what.
Passing data into templates
When rendering views, we can pass in a dictionary with a key-value pair(here is {'name': 'Jump Roper'}) to the template home.html.
In the template, we retrieve the dictionary values with the {{ key }} notation, for example {{ name }}.
{{ }} is the variable syntax from Django Template Language(DTL).
