[Product-Developers] How to tell a type it is only addable to a certain type

[Hedley Roos]

Make sure global_allow is False in profiles/default/types/YourType.xml

Let's say you want YourType to be addable to Folders. Go to ZMI, 
portal_types, Folder and adjust Allowed Content Types to include 
YourType. You may want to do this programatically.

If, however, you want YourType to be addable to only a single folder and 
not all folders, then this piece of code will do that.

folder.setConstrainTypesMode(1)
folder.setLocallyAllowedTypes('YourType')

This overrides the allowed types for a single instance of Folder.

Hope that helps
