# Previously, the relation between an invoice and the bought objects where stored disparately:
|

|
# Invoice.invoiced_id & Invoice.invoiced_type saved the main object, and if a subscription was took at the same time of
|
||
|
|
# a reservation (the only case where two object were bought at the same time), the reservation was saved in
|

# Invoice.invoiced and the subscription was saved in InvoiceItem.subscription_id

# From this migration, everything will be saved in InvoiceItems.object_id & InvoiceItem.object_type. This will be more
