Installing the product

Congratulations! You have created your first Archetypes-based content type.

Let's add it in our already configured Zope instance to see what it looks like.

Instead of using the ArchGenXML product as it is, we will wrap it in an egg structure and install it in the src folder of our buildout.

How to do it…

First of all, we must create the egg structure that will hold the ArchGenXML generated code:

  1. Go to your buildout folder and create — if not created yet — a src folder.

    mkdir ./src
  2. Then call paster to create the egg folder structure:

    paster create -t plone 

It will start a very short wizard to select some options for our product. Most important is the first one:



Enter project name

Products.poxContentTypes: Although the project name might not necessarily match the full name of the package, they usually do.

Expert mode

easy: The expert mode option is new with ZopeSkel 2.15. If you choose other than easy, you will be prompted for the namespace and package...
