[web2py] cosmetic dropbox request

[Jean-Guy]

Hello,

I use %()s in a IS_IN_DB validator like this :
db.reg_registry.registry_id.requires = 
IS_IN_DB(db,'reg_registry.registry_id','%(num_part1)s-%(num_part2)s-%(num_part3)s')

return

num_part1 -num_part2 -num_part3

My problem is that %()s seems to add whitespace at the end of the string 
what I don't want...

What I want :

num_part1-num_part2-num_part3

I try with rstrip() but can't figure how to make it works.

Thanks.

Jonhy
