So I decided to read the docs, as I haven't done SO in 9 months.
First, you shouldn't be overriding __init__, sorry for that
misdirection. Second, I actually wrote the code and thought about it a
bit more.
It turns out that the problem is simply that the test for the _set_ is
happening before the other attribute comes into existence. Sorry about
sending you down the wrong path.
You had a few other problems, '' evaluates to False and not None so
you can wind up with both having '', which seems to be not what you
intended. Also doing self.otherValue = None will set both to None.
Here's a working version of your test class:
class class1(SQLObject):
prop_1 = StringCol(default='')
prop_2 = StringCol(default='')
def _set_prop_1(self, value):
self._SO_set_prop_1(value)
if hasattr(self,'prop_2') and self.prop_2 is not None:
self._SO_set_prop_2(None)
def _set_prop_2(self, value):
self._SO_set_prop_2(value)
if hasattr(self,'prop_1') and self.prop_1 is not None:
self._SO_set_prop_1(None)
And the output:
In [1]: x = class1()
In [2]: x
Out[2]: <class1 1 prop_1=None prop_2=''>
In [3]: x.prop_1 = '2'
In [4]: x
Out[4]: <class1 1 prop_1='2' prop_2=None>
