Here's the associations that I have set up:
Partner hasMany PartnerInvolvement
Product hasMany PartnerInvolvement
PartnerInvolvementType hasMany PartnerInvolvement
PartnerInvolvement belongsTo Partner, Product, PartnerInvolvementType
The $hasMany relationship is defined the same way in all 3 of the Partner,
Product, PartnerInvolvementType models:
class Product {
public $hasMany = array(
'PartnerInvolvement' => array(
'className' => 'PartnerInvolvement',
'foreignKey' => 'product_id',
'dependent' => true,
'unique' => 'keepExisting'
)
);
}
When adding/editing a new Product, I want to be able to choose which
Partners are involved with that Product, which PartnerInvolvementType it
is, and create new PartnerInvolvement relationships from that data.
Here is the data that I am trying to save:
Array
(
[Product] => Array
(
[id] => 2981
[name] => Laurie Amerson Rental itr1229
[product_type_id] => 12
[default_price] => 0.00
)
[PartnerInvolvement] => Array
(
[0] => Array
(
[partner_id] => 1
[partner_involvement_type_id] => 1
)
[1] => Array
(
[partner_id] => 2
[partner_involvement_type_id] => 1
)
)
)
My app is creating a new PartnerInvolvement entry any time I try to save this
data. I am trying to restrain it so that a unique combination of product_id,
partner_id, partner_involvement_type_id is only saved once. Any suggestions?
Should I go back to using a HABTM instead of a hasMany through relationship?
