Filtering a has_many :through relationship index-page

[Solomon Seal]

I am trying to use <filter-menu> to filter the index page of one of my controllers.  It works for object that are a part of the model directly, but does not work for any of the child objects.  Code examples below:

======================================

class Plant < ActiveRecord::Base

  hobo_model # Don't put anything above this

  fields do

    name          :string

    timestamps

  end

  has_many :bloom_color, :through => :bloom_color_assignments, :accessible => true

  has_many :bloom_color_assignments, :dependent => :destroy

  children    :bloom_color

<--cut-->

end

======================================

class BloomColor < ActiveRecord::Base

  hobo_model # Don't put anything above this

  fields do

    name        :string

    timestamps

  end

  

  validates_presence_of :name

  

  set_default_order "name" 

    

  has_many :plants, :through => :bloom_color_assignments

  has_many :bloom_color_assignments, :dependent => :destroy

  

  children :plants

<--cut-->

end

======================================

class BloomColorAssignment < ActiveRecord::Base

  hobo_model # Don't put anything above this

  fields do

    timestamps

  end

    

  belongs_to :plant

  belongs_to :bloom_color

<--cut-->

end

======================================

I started out with something along the lines of:

======================================

Plant.apply_scopes(:bloom_color_is  => params[:bloomcolor])

======================================

in my controller, but get a "undefined method :bloom_color_is...." error.

Sorry if I have made any mistakes or haven't followed any conventions or best practices here. I am new to both Hobo and Rails.  What would you suggest I do to correct this, or to do better?

there's nothing wrong with the Google moderation queue, because I

Try bloom_color_id_is => params[:bloom_color_id].

One other thing - have you tried pluralizing this? Hobo makes a fair number of assumptions when generating scopes, and having a has_many with a singular name may cause weird results.
