Model definition: HasMany/BelongsTo not being hydrated

[xewl]

I was trying to define a model for Sales Order, with a relation for its Lines. I saw that the PurchaseOrder model in the test folders had a ::read method to grab with an array of id's. And given there are Relation Attribute types like HasMany , BelongsTo, etc I thought it would be easy to get Lines etc.

But.. :D

Situation 1:

Using Service Provider directly Works, order_line is filled and can be used.

#[Model('sale.order.line')]
class SaleOrderLine extends OdooModel {}

public function debug(Odoo $odoo, int $id)
{
    $order = $odoo->find('sale.order', $id);
    $lines = SaleOrderLine::read($order->order_line) // :array 
}

Situation 2:

Using Model Error: App\Odoo\SaleOrder::$orderLine must not be accessed before initialization

#[Model('sale.order.line')]
class SaleOrderLine extends OdooModel {}

#[Model('sale.order')]
class SaleOrder extends OdooModel
{
    // #[Field('order_line')] // this one works
    #[HasMany(SaleOrderLine::class, 'order_line')]
    public array $orderLine;
    
    public function orderLines(): array
    {
        return SaleOrderLine::read($this->orderLine); // *
    }
}

public function debug(int $id)
{
    $order = SaleOrder::find($id);
    // then, where it fails:
    $lines = $order->orderLine; // error: see above
    $lines = $order->orderLines(); // error: see above
}

(kept it "orderLine" for clarity, could've used lines of course, order_line has the same result)

I'm guessing the relations aren't fully working yet, while filling up the model? ( OdooModel::hydrate , which is on the HasFields trait)?

There's currently only a test to check for saving a relation (PurchaseOrder). So I'm not quite sure how to go about this.

• Extend the relation classes eg HasMany
• Extend the hydrate method to fill the property on the model properly, based on the given relation?
• Use another definition, to just keep the ID array instead: #[Field('order_line')] Which does work in this case, but would stop me from using the Model to save the data and force me to grab the IDs in an array.)
