[SQLObject] picked column type

[Martin B. <mar...@gm...>]

hi

some more tinkering.  i want to store lists of stuff.

i would use a table for the stuff itself, but i still need to store a
variable-length list of indexes to those objects.  seems to me like a
typical problem, but i have little direct experience with SQL... how
does one normally store variable-length lists of indexes or "stuff"
with SQL?

i saw that Postgres supports an array type, but there doesn't seem to
be support for arrays in sqlobject.

anyway, so after the binary type support i thought it would be cool to
have a PickledCol column type, where pickling and unpickling would
occur automatically.  i fiddled with this for a short time and came up
with the patch below (over 537).  i'm not quite sure why toPython gets
called multiple times with different types, i didn't take the time to
debug the issue yet, but this seems to work.  it's fun, you can store
anything in the column.

cheers,
