Getting Set Up

Prerequisites: CKAN Installed

To develop an extension it's best to have CKAN installed. To install CKAN see: http://ckan.org/install/

Strictly you don't need CKAN installed to develop extension but without it installed it will be impossible to test or view your efforts!

Code for this Tutorial

You can get the code for this tutorial from the mercurial repository:

• https://bitbucket.org/okfn/ckanext-helloworld

Or download individual steps directory from the downloads directory:

• https://bitbucket.org/okfn/ckanext-helloworld/downloads

Tutorial

The aim: create a new /helloworld page on the CKAN site with some simple interactivity

Step 1: Create the extension

We suggest you skip this step and just grab the step 1 code from the repo or the downloads area.

Step 2: Create a 'controller' to handle the helloworld action

Here we copy one I made earlier
