Customising types with add views
|
|
Hi,
Currently, we have this situation (on trunk):
- Add views are looked up by evaluating the FTI add_view_expr
- The default/conventional add_view_expr is
string:${folder_url}/++add++<typename>
- This will look for an adapter (context, request, fti) with name =
fti.factory and return that as the add view
Let's consider a type Alpha that has a custom add form registered as
such a (context, request, fti) adapter with name "Alpha". fti.factory is
"Alpha", and there's a corresponding IFactory utility (with name "Alpha").
Now, let's say I want to create a new type Beta (e.g. by copying the FTI
object TTW), based on Alpha. I want this to use Alpha's add form, but
construct objects with portal_type Beta.
Is this possible? If I set Beta's fti.factory to be something other than
"Alpha", then it won't find the add view, but if fti.factory is "Alpha"
then the objects constructed will use Alpha's factory.
I can't quite decide whether this is a problem in real life or not,
although it does seem a bit strange that the add view adapter name and
the factory utility name have to be the same.
Would it make sense to decouple these, e.g. with a new "add_view_name"
property?
