Sti object as child of normal object has mutually exclusive issue.
Reported by Don Ziesig | January 28th, 2011 @ 03:27 PM | in Hobo 1.3 (Rails 3)
I have a normal object - property - with a child - transaction - that uses sti to specialize the different types of transactions allowed on a property (e.g. seller_transaction, buyer_transaction).
In the property.rb file, I have:
has_many :transactions ### Problem line
has_many :buyer_transactions
has_many :seller_transactions
children :seller_transactions
children :buyer_transactions
If the problem line above is present, I can not create seller_transactions or buyer_transactions. The Add boxes are visible on the property page(after a little editing of the dryml), but the contents are absent and there is no Add button. If I enter the transactions directly in the database, I can view the list of all transactions associated with a property (again with a little editing of the dryml) using the line:
<collection:transactions param/>
On the other hand, if the problem line is absent, I can create both seller_transactions and buyer_transactions (after a little editing of the dryml), but I can not (crash) view a list of transactions associated with the property. It does NOT like the line
<collection:transactions param/>
As a work around, I essentially have to separate the two (in the real app many more) lines:
<collection:buyer_transactions param/>
<collection:seller_transactions param/>
which is a real PITA (and will cause the users grief because they will want to sort the transactions as a group, not separately).

I tried your app, and what you are trying to do seems a customization on the show page.
The canonical way to add children to a parent record is just add :accessible => true to the Property model for the transaction type that you want to be able to add (incuded the general transaction) and edit it in the property EDIT/NEW page.
That is working in your attached app, so there is no bugs here.
I suggest you to post in the hobousers group, so somebody will help you to customize what you need.

well, if you add:
auto_actions_for :property, [:create]
to the TransactionController your app will get the route that the form needs in order to be posted somewhere, and it will work with the transactions children out of the box. If you want to use the STI base class instead the sti classes, you have also to customize the transactions form so you can choose which kind of transaction will be created.
So no bugs again :-@
