[Zope-CMF] Filtering Allowed Content Types on Portal Folders

[Carl Rendell]

I've been conversing with Andrew Sawyers on a Folder product he has 
been working on, and poking around the CMF products trying to 
answer my question -

Can allowed content types be set on standard CMFCore.PortalFolder 
objects. At this point I'd like to get simple confirmation as 
follows -

o Standard CMF expects allowed content types to be set in the 
portal_types tool (portal type for the product)

o The CMFCore.PortalFolder class has no provision for restricting 
content types so it is not possible to add a list of allowed 
content types to a standard portal folder.

Assuming both are true, then the recourse is to either -

1. Create a new portal_type wired up with portal folder and set 
allowed content types there (zmi based fix)

2. Create a new product with a classes that add provisions for 
allowed content types as attribute(s) so that the allowed content 
types can be set via the user interface (skins).

Andrew had demonstrated that #2 requires a change to 
folder_factories skins (dtml/zpt) as well.

In my mind this reflects the bias current versions of Zope have 
toward the zmi interface for things that users would like to do in 
the user interface. Not throwing stones mind you.. just an 
observation. Admittedly my personal bias is toward separating all 
content management and organization functions from administration 
such that 'normal' users never touch the zmi. I prefer a clean 
separation of administration (products, tools, catalogs, etc) from 
content and organization functions (add/modify/delete/undo).
