All Howtos and Tutorials

All Grok howtos and tutorials.

Adapters

This section tries to be a short introduction to adapters as they are used in Zope component architecture; thus Grok, and as an example, we will use the ``NameChooser`` mentioned in the previous section, and implement our own version of it.

Naming Content

In the `Adding Objects`_, we made a form that creates new polls and adds them to a container. But we overlooked a problem in the way that Grok object traversal works.

Interfaces

In the previous section, we defined a schema for the ``Poll`` class manually, which is not a good solution, as we might need multiple forms for them, and thus will need to repeat a lot of code.

Introduction

The core audience of this tutorial is programmers that already are already familiar with Python and Web development, but might not know anything about Zope.

The First View

We will now implement the first view of the poller application; which will list all the polls for the users, and provide a link to add new polls.

Poller Idea

The poller application, that we will implement in this tutorial, is a simple Web application, which let's the users create polls with multiple voting options.
