Hi, I am trying to sote pairs in a table as follows:
#--------------------------------------------------------------------------------------
from elixir import *
metadata.bind = "sqlite:///:memory:"
metadata.bind.echo = False
class Pairs(Entity):
name = Field(String(50), primary_key = True)
other = OneToOne('Pairs', inverse = 'other')
def __init__(self, name):
self.name = name
def pair(name1, name2):
p1, p2 = Pairs(name1), Pairs(name2)
p1.other = p2
if __name__ == '__main__':
setup_all()
create_all()
pair('p1', 'p2')
#--------------------------------------------------------------------------------------
I am not very famiiar with SQL etc. but logically this seems possible
(please orrect me if I am wrong). However I get the following error:
------------------------
File "D:\Documents\Code\Eclipse\workspace\SQLAdata\src\tests.py", line
22, in <module>
setup_all()
File "build\bdist.win-amd64\egg\elixir\__init__.py", line 94, in

in inverse
AssertionError: Relationships 'other' in entity 'Pair' and 'other' in
entity 'Pair' cannot be inverse of each other because their types do
not form a valid combination.
------------------------
Can anyone help me to understand the error and possibly fix it?
Thanks in advance, Lars
