issue can't convert Time into String

[lothar59]

I have this issue when trying to create a new record. I'm using rails 2.3.4

columns = [:libelle]
=> [:libelle]
values = ["russe"]
=> ["russe"]
Langue.import columns, values
TypeError: can't convert Time into String

@lothar59, what version of Rails/ActiveRecord are using?

[lothar59]

hum I have both activerecord (3.1.1, 2.3.4), but I'm guessing that If I'm using rails 2.3.4 then I'm using also activerecord 2.3.4. Am I guessing wrong ? I have this in my environment file : RAILS_GEM_VERSION = '2.3.4'

EDIT : hum and rails I have 2.3.4
