Betternestedset talk - Dec 2007 - Validations

Hi all,

Is there any way to cause move_to_child_of to trigger a validation 
check?  In my application, there are certain kinds of nodes that aren''t
allowed to have children.  I have code in my validate method to check 
for this, but it doesn''t get called when nodes are moved to different 
parents.

If there isn''t a way to do it right now (I didn''t see any way
to do it),
it seems like it should be fairly easy to add.  Perhaps just wrap the 
update_all call in move_to inside a transaction and call save! 
afterward.  I could try to write a patch for this if that sounds like 
the right way to go.

Also, is using the trunk branch in production safe?  I noticed that 
there hasn''t been a stable release in quite a while, but there are 
changes required for compatibility with Rails 2.0 that are only in trunk.

Thanks!

I have been using a trunk version that''s newer than the current
releases in production without any issues.  I hadn''t realized that
the Rails 2.0 issues have already been resolved.  I had known, I would
be using the newest trunk version rather  than
making the necessary changes to ActiveRecord.  I must have missed that
shout out from the developers.
