Code explanation
================

- There are two more things Flask can do for you: serve static files and render templates
- Everything you put to "static" will be available at http://127.0.0.1:5000/static/.
  Check out http://127.0.0.1:5000/static/background.jpg
- HTML-files, put to templates can be used as so-called "jinja-templates".
- Jinja templates look like regular HTML files, but inclusions like {{ var }}
  or {% for i in something %}...{% endfor %} interpreted on the server
  side on the fly
- There is a bolierplate code in splash.html and styles.css to show
  "inspiring splash thing"
- flask.render_template('splash.html', text=text) does the trick


Code run
========

Try these URLs:

- http://127.0.0.1:5000
- http://127.0.0.1:5000/user/Roman
- http://127.0.0.1:5000/user/%3Ch1%3ERoman

You can see how render_template works if you run a special
"flask-activated" shell with:

$ FLASK_APP=07_web_hello_world_template.py flask shell
>>> import flask
>>> flask.render_template('splash.html', text='Hello world')


Documentation
===================

- Jinja documentation: http://jinja.pocoo.org/docs/


Practical task
==============

Modify the Hello World example to show some random quotes of wisdom instead.

- http://127.0.0.1:5000 has to show one randomly chosen quote from quotes.txt
  or quotes.csv
- http://127.0.0.1:5000/<quote_id> has to show the quote with the given id
  from quotes.csv. If nothing is found, it has to show the text
  "nothing is found"
