41	Single table non polymorphic inheritance clashes with autoload	guest	ged	"Both super and sub classes tries to load columns from the database, which results in column allready exist errors. 

Reproducer:

create a table with:

  sqlite3 test.sqlite 'CREATE TABLE __main___father (id INTEGER PRIMARY KEY);'

test it with:


{{{
from elixir import *

metadata.bind = ""sqlite:///test.sqlite""

options_defaults[""polymorphic""] = False
options_defaults[""autoload""] = True

class Father(Entity): pass
class Son(Father): pass

setup_all()

}}}

result:


{{{
$ python test.py 
Traceback (most recent call last):
