Jinja2 ｜ Python template engine

** Note that I researched the template engine in Python. ** **

There are various names such as Mako, Genshi, Jinja2 (for some reason, there are many Japanese names)
As a framework, Bottle is lightweight and nice
This is the definitive edition! There is no such thing, but Jinja2 seems to be easy and easy to understand

So I tried Jinja2. The origin of the name is template ⇒ temple ⇒ shrine. ‥I see.

1) Install

The environment is Sakura VPS (CentOS)

yum install python-pip (only if you don't have pip yet)
pip install jinja2

2) Apache settings (only for those who haven't done so yet)

Configure Apache so that Python works as CGI.

vi /etc/httpd/conf/httpd.conf

Change 2 places written in httpd.conf with vi editor etc.

`httpd.conf`


１）
<Directory "/var/www/html">
    Options Indexes FollowSymLinks
↓ Added ExecCGI
    Options Indexes FollowSymLinks ExecCGI
</Directory>

２）
#AddHandler cgi-script .cgi
↓ Uncomment and.py added
AddHandler cgi-script .cgi .py

After saving the settings, restart Apache.

service httpd restart

3) Template

`html:hello.tpl.html（UTF-8）`


<html>
<body>
Welcome,{{ shop }}is.
<hr>
<ul>
{% for food in foods %}
    <li>{{ loop.index }}: {{ food.name }} － {{ food.price }}Circle</li>
{% endfor %}
</ul>
</body>
</html>

4) Front side (side that calls the template)

All Python source files are written in UTF-8, and the permissions after uploading are 755 (give execute permission). Also, the following output is required before outputting HTML. (If you forget it, an error will occur immediately)

print "Content-Type: text/html\n";

`hello.py（UTF-8）`


#!/usr/bin/python
# -*- coding: utf-8 -*-
from jinja2 import Environment, FileSystemLoader
env = Environment(loader=FileSystemLoader('./', encoding='utf8'))
tpl = env.get_template('hello.tpl.html')

foods = []
foods.append({'name':u'ramen', 'price':400})
foods.append({'name':u'Fried rice',   'price':500})
foods.append({'name':u'Tianjin rice',   'price':600})

html = tpl.render({'shop':u'Gokuken', 'foods':foods})
print 'Content-Type: text/html; charset=utf-8\n'
print html.encode('utf-8')

After that, access hello.py from your browser and check.
