Does a Mapper MappedStringForeignKey check for existence when set?

[Peter Robinett]

I having some memory problems that I suspect are caused, at the end of
the day, by creating many Mapper instances and setting their
MappedStringForeignKey property. When I set it, is it being looked up
in the database? Based on a previous thread[1], I suspect it is. This
is with 1.1-M5.

Thanks,
Peter Robinett

It's not being looked up in the database until you call .obj on the field.

Ok, thanks, that makes sense.
