[Zope-PTK] Procedure: Adding a Portal Content ZClass

[Mike Pelletier]

    Hi.  I need to write down this checklist while I still remember all
the steps.  I'm sending it here because it may be useful to others, at
least until it changes again.

To create a new kind of Portal Content:

  - Add a class to PTKBase/ZopeOrg/PortalContent.py.  It need not subclass
    anything, because it's going to be mixed in with other classes in the
    ZClass.

  - Make the class available as a ZClass base by editing
    PTKBase/ZopeOrg/__init__.py.  (Follow the example of the other
    classes.)

  - Create a ZClass, subclassing first the class you created in the first
    step, then 'ZopeOrg: Portal Content'.

  - Delete the generated Permission object

  - Insert at minimum the following to the <dtml-with> portion of the add
    method:

<dtml-call "propertysheets.PortalContent.manage_editPropterties(REQUEST)">

  - Change the redirect portion of the add method to honour the
    wizard_destination parameter:

<dtml-if wizard_destination>
 <dtml-call "RESPONSE.redirect(wizard_destination)">
<dtml-elif DestinationURL>
 ...

  - In the ZClass's 'Define Permissions' view, set 'Create Class Instace'
    to 'Add Portal Content'.

  - Also set the Factory's 'Permission' value to 'Add Portal Content'.

  - To provide an 'Edit this page' interface, add a method called
    'user_edit_form' to the ZClass.

  - To make the ZClass available to Members, create a Wizard object in
    /Control_Panel/Products/ZopeOrg/ZopeOrgPortal/Wizards.  It's 'action'
    property should be set to 'manage_addProduct/ZopeOrg/your_zclass_add'.
