Web development simplified. An MVC framework supporting Python 3.

Project description

What is Giotto?

Giotto is a python web framework. It encourages a functional style where model, view and controller code is strongly decoupled.

Key Features of Giotto include:

  • Extremely terse code. A full featured blog application is under 300 lines of code (including templates)

  • Generic views, generic models and multiple pluggable controllers.

  • Free RESTful interface along with your normal “browser POST” CRUD site.

  • Functional CRUD patterns that do away with the need for django-style form objects.

  • Automatic URL routing.

  • Built in cache (supports Redis and Memcache, and an API for supporting any other engines)

  • SQLAlchemy for database persistence.

  • Jinja2 for HTML templates (with an API for extending for other template engines)

Getting started

Install and create base project files:

pip install giotto
mkdir demo
giotto create http

Now your project is initialized. Open the and add the following:

from giotto.programs import ProgramManifest, GiottoProgram
from giotto.views import jinja_template, BasicView

def multiply(x, y):
    x = int(x or 0)
    y = int(y or y)
    return {'x': x, 'y': y, 'result': x * y}

manifest = ProgramManifest({
    'multiply': GiottoProgram(

Now create a file called multiply.html:

<!DOCTYPE html>
        {{ data.x }} * {{ data.y }} == <strong>{{ data.result }}</strong>

Or if you’re too lazy to make a template, set the view keyword argument to just BasicView() to use the generic view.

Run the development server:

$ giotto http --run

Point your browser to http://localhost:5000/multiply?x=3&y=3. Additionaly, try http://localhost:5000/multiply.json?x=3&y=3. You can also invoke your multiply program through the command line:

$ giotto create cmd
$ giotto cmd multiply --x=4 --y=2


$ giotto cmd multiply.html --x=4 --y=2

You can also use positional arguments:

$ giotto cmd multiply/4/6
