Google-maps-for-Rails - undefined method `gmaps' for (object) in rake task

Question

When I run a rake task that involves a model with gmaps4rails enabled I get this error, and if I comment the model so it's not acts_as_gmappable it completes properly.

enter code here
troy$ rake populate:scans --trace
** Invoke populate:scans (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute populate:scans

Sorry - email notifications aren't coming from this site - I invited you to a project to see some code - we can post the update here if you get some time to check it out — Troy Anderson, Jul 21 '11 at 05:48
Why is this necessary? Is it an incompatibility with Ruby 1.9 or Rails 3? Nice to know the fix, but i'd also like to understand the root cause that necessitated the fix. — dlehman, Oct 05 '11 at 19:12

Solution 1:

acts_as_gmappable :process_geocoding => false

Solution 2:

When you're creating an instance of your model, do:

@scan.instance_eval do
  def process_geocoding
    true
  end
end
