Question

I am trying to do an after_save conditional callback

after_save :change_rel_status, :if => :relation_type_id == 1

def change_rel_status
  self.status = "Confirmed"
  self.save
end

But I get the error message undefined method after_save for false:FalseClass

{"utf8"=>"✓",
"_method"=>"put",
"authenticity_token"=>"f4IN...=",
"relationship"=>{"relation_type_id"=>"1",
"category_ids"=>[""]},
"commit"=>"Update Relationship",
"id"=>"19"}

I am not sure if it’s because the form also has other attributes from other models that were not updated?

Thanks.

May I suggest something simpler:

before_save :change_rel_status

def change_rel_status
  if params[:relationship][:relation_type_id] == 1
    self.status = "Confirmed"
  end
end
