counter_cache rails a child creation should increment the count intwo different models based on condition

Question

Hi,

I have 3 models

Recommendation Job Qualification

Recommendation model has two fields as work_type and work_id(foreign key for job/qualification based on work_type as "J"/"Q")

I am facing problem in using counter_cache

I have done this in recommendation.rb

belongs_to :job , :counter_cache => true, :foreign_key => "work_id" belongs_to :qualification , :counter_cache => true, :foreign_key => "work_id"

and

in job and qualification model files

has_many :recommendations , :conditions => {:work_type => "J"}

has_many :recommendations , :conditions => {:work_type => "Q"}

Both Job and Qualification Models have a column as recommendations_count

The problem is every time an object of recommendation is created count is increased in the both the models

Please help me with this

Thanks
