[SQLObject] Feature Request: Can Registry call a factory method if a class is not found?

[Scott S. <sc...@st...>]

Ian,

I have successfully been using SQLObject svn trunk for a few days now, 
without modifications.  I have implemented automatic class generation 
by reading information from the database about classes and their 
columns and joins.  I did this by extending MetaSQLObject with my own 
behavior, and a factory method called getClass(classname), which checks 
the registry, and then constructs a new class if the registry does not 
contain the proper class.

The problem I am running into now, is when you have joined classes, the 
joined classes have to be explicitly loaded.  In your users/roles 
example, my code would have to look something like this:
userClass = getClass('user')
roleClass = getClass('role') #if this is not called here, user.roles 
will not be defined, because the role class is not in the registry
user = userClass.get(1)
print list(user.roles[0])

It would great if the registry was allowed to have a factory method set 
to attempt automatic class creation if the class does not exist.  If I 
coded this up as a patch, would it be accepted?

Thanks,
Scott
