If the issue is only about the lambda being too big, you could do:
adder: lambda{|*args| your_method(*args)}
def your_method(custom_product, reason, comment, available_at = nil)
DisabledCustomProductsLocation.update_or_create(
{ location_id: id, custom_product_id: custom_product.id },
available_at: available_at, reason: reason, comment: comment)
end
An alternative approach is to do this after the association and not use the
:adder option, since the :adder option just defines this method:
private def _add_disabled_custom_product(custom_product, reason, comment,
available_at = nil)
DisabledCustomProductsLocation.update_or_create(
{ location_id: id, custom_product_id: custom_product.id },
available_at: available_at, reason: reason, comment: comment)
end
Thanks,
Jeremy
