I am trying to use activerecord-import, but I can't seem to get my application to recognize its existence.
I get
undefined method `supports_import?' for #<Class:...>
or
undefined method `import' for #<Class:...>
no matter what I do. I've been googling this for days and trying everything I can think of
It worked when we had rails 2.3.5 and ar-extensions, but since upgrading to rails 3.2 it has been broken.
Everyone says the solution is to use activerecord-import, but I don't seem to know how to do that. I have installed the gem -- I believe the correct version for my version of ActiveRecord -- and I've required it in my code, but there must be some other thing I have to do.
I have this in my Gemfile:
gem 'activerecord-import', "~> 0.3.0"
this in my code:
require 'activerecord-import'
and this is my gem list:
$ gem list
