I have a system where an account can have many different types of order ( SalesOrder, PurchaseOrder, SalesInvoice, PurchaseInvoice, etc)
I'm using single table inheritance and it works really well, even down to the level of controllers and views.
But how do I declare inverse_of on the associations.
In my account it's easy on each declaration
has_many sales_orders, inverse_of: :account
has_many purchase_orders, inverse_of: account
...
But on the base model for all the types of orders I have"
belongs_to :account
I want to add inverse_of: xyz where xyz is worked out dynamically according to the model. For example, for a SaleOrder in would be inverse_of: :sales_orders.
But I want to keep the code in the base model. I do not want to go into the SalesOrder and write belongs_to :account, inverse_of: :sales_orders there.
How can I do it? Can I use a lambda on the association declaration that returns the right value according to the sub-class being used?
