Rails run object method on itself periodically

Question

I need to run a method once daily in a Rails application.

I'm thinking about using the whenever gem, but I realize I have a bit of a problem.

I need to run the method on an instance of an object. So I can't just have something like:

every 1.day do
    runner 'Object.method'
end

I'm thinking about doing something like

every 1.day do
  runner 'Object.where(status: "the_status_i_want").each { |object| object.method }'
end

But I have no clue how to test this behavior from within 'whenever.'

Any ideas?

Ryan Bates has a nice episode on integrating whenever gem into Rails
