Polymorphic associations and hobo g migration

[Bob Sleys]

Running hobo 1.3 it appears that running hobo g migration doesn't work when there is a polymorphic association between models.

First here is the errror.

Hobo Command Line Interface 1.3.0

/home/bsleys/.rvm/gems/ruby-1.8.7-p352@HazMatTracking/bundler/gems/hobo-900179e80104/hobo/lib/generators/hobo/routes/router.rb:56:in `owner_routes': Hob routing error -- can't find reverse association for Sample#sample_test (e.g. the :has_many that corresponds to a :belongs_to) (Hobo::Error)

And my models, extra stuff clipped.

class Sample < ActiveRecord::Base

  hobo_model # Don't put anything above this

  fields do

    positive :boolean

    result   :string

    timestamps

  end

  belongs_to :sample_test, :polymorphic => true

  ....

end

class Asbestos < ActiveRecord::Base

  hobo_model # Don't put anything above this

  fields do

    name :string

    timestamps

  end

  belongs_to :material

  has_many :samples, :as => :sample_test

  ...

end

class Lead < ActiveRecord::Base

  hobo_model # Don't put anything above this

  fields do

    note :text

    timestamps

  end

  belongs_to :material

  has_many :samples, :as => :sample_test

  ...

end

class Pcb < ActiveRecord::Base

  hobo_model # Don't put anything above this

  fields do

    name :string

    notes :text

    timestamps

  end

  belongs_to :material

  has_many :samples, :as => :sample_test

  ...

end

I think you're getting the problem from the auto_actions_for, not the polymorphic bit.  though it may be having a problem making the auto_actions_for a polymorphic association.

I believe you are correct.  I remove the auto_actions_for from the controller and the migration worked.  So now to just find a way around the auto_actions_for problem.

Actually, it looks like it's blowing up even before it gets there - this error is from the route generator that runs on startup. Judging from the data, it looks like you've got an auto_actions_for on the polymorphic association, which I don't believe will work out of the box...
