#1412: Doctrine::createTablesFromModels() fails to build records related to
abstract records

-----------------------------------+----------------------------------------
I will give a small schema example here (exemplary only, I haven't tested
it):
{{{
detect_relations: true
Tree:
columns:
name: string
# this class is declared abstract in the model
Fruit:
columns:
color: string
tree_id: integer
Apple:
inheritance:
extends: Fruit
type: concrete
Orange:
inheritance:
extends: Fruit
type: concrete
}}}
Without the relation Fruit->Tree, this example works perfectly fine. I end
up with the tables "tree", "apple" and "orange" which is what I want.
Once I add the relation Fruit->Tree though, Doctrine has problems. When
building the SQL for Tree, it tries to build the definitions of all
related records (Fruit). In the process of this definition building
Doctrine tries to instantiate the abstract class Fruit, which fails (of
course).
The relevant part of the exception trace looks like the following:
{{{

}}}
FYI: getRelations() is called on the Tree table and returns the only
relation "Fruit". Then Doctrine tries to completeDefinition() Fruit and in
the end tries to instantiate Fruit in FruitTable->initDefinition().
