[Zope] Data.fs gone crazy

[Tom Cameron]

Steve,
Thanks very much for all the help. In the end I exported out all the objects
I wanted, then I reimported them into a clean Data.fs

If I get time I will experiment with your stuff to find out more. I kept the
old Data.fs just in case.

I assume this is some sort of bug.

Regards
Tom

=> Hi Tom,
=>
=> 	I just constructed this scenario:
=>
=> 1) Install a Python Product that is a base class for some ZClasses.
=>
=> 2) Install some ZClasses that inherit from the Python Product class
=>
=> 3) Delete the Python Product and the ZClasses
=>
=> You may now have (I did) some "ghost" zclass entries in the Product
=> registry. The only way I found to get rid of them was to run the code
=> below. (stop Zope, cd to 'lib/python',  execute fixit.py from the
=> command line.) You might try running it a few times with the last two
=> lines commented out to make sure your only removing the zclasses you
=> mean to. You might also make a backup of your Data.fs before you do
=> anything else. I have no idea if this has any other nasty side effects,
=> but it worked for me.
=>
=> Good Luck!

=> fixit.py:

=> x = Zope.app(  )
=>
=> theList = list( x._getProductRegistryData('zclasses'))
=>
=> newList = []
=> for d in theList:
=>     if d['id'] == 'the name of your zclass':
=>         print "Skipping  .. ", d
=>     else:
=>         newList.append(d)
=>
=> print newList
=>
=> x._setProductRegistryData( 'zclasses', tuple(newList ))
=>
=> get_transaction().commit()
