Rspec + Rails: table_name_prefix not loaded for module -

-

when run rspec on specific file:

rspec spec/models/my_namespace/my_model_spec.rb

i run error because rspec appears not load app/models/my_namespace.rb, contains declaration of self.table_name_prefix. in fact, if use pry , run mynamepsace.table_name_prefix # => nomethoderror: undefined method ``table_name_prefix'.

when try query db rails console (no rspec), works, though: mynamespace::mymodel.where(foo:'bar') # => [...]

any idea problem or fix is?

rails 3.2.14, ruby 1.9.3, debian

at top of spec file:

require_relative '../../../app/models/my_namespace'

this load namespace file specifies table prefix.
