HABTM Validation Error doesn't delete join table record

[richardpeng]

I have the following self-referencing association:

has_and_belongs_to_many :parts, class_name: Asset, join_table: :stocks, foreign_key: :asset_id, association_foreign_key: :part_id

and this validation:

 validate :stock_check

  def stock_check
    parts.each do |part|
      if Stock.where(part_id: part.id).size > part[:stock]
        errors.add(:base, 'Not enough stock to assign additional assets.')
      end
    end
  end

When the validation fails, the record is left in the join table. Looking at the SQL queries, the join table records are created in a separate transaction from the ones for the main record and so isn't rolled back when the validation fails.

I am not being able to delete HABTM records even without validation
