[web2py] is_in_db error message translation

[Richard Vézina]

Hello,

I try this :
db.table1.field1.requires=\

 IS_IN_DB(db,'othertable.field1',orderby=('field1'),error_message=T('value
not available'))

But not working...

How may I translate the IS_IN_DB error message?

Should we have an other attribute for IS_IN_DB function?
