推动多种行为（例如i18n &&可版本控制）

Question

I am trying out Propel and seeing if its acceptable for my project.

When combining multiple Behaviors, a certain behavior does not inherit other behaviors.

Example schema.xml:

<table name="item" phpName="Item">
    <column name="id" type="integer" required="true" primaryKey="true" autoIncrement="true"/>
    <column name="name" type="varchar" size="255" required="true" />

    <behavior name="sluggable" />

    <behavior name="sortable" />

    <behavior name="i18n">
        <parameter name="i18n_columns" value="name" />
    </behavior>

    <behavior name="versionable">
        <parameter name="log_created_at" value="true" />
        <parameter name="log_created_by" value="true" />
        <parameter name="log_comment" value="true" />
    </behavior>
</table>

Example controller:

// create example records
$item = new Item();

// create version with i18n record
$item->setLocale('en_US');
$item->setName('Hello');
$item->save();

// create version with i18n record
$item->setLocale('is_IS');
$item->setName('World');
$item->save();

// get created newly created item
$item = ItemQuery::create()
  ->findPK(1);

foreach ($item->getAllVersions() as $itemVersion)
{
    echo 'us name: ' . $itemVersion->setLocale('en_US')->getName() . "\n";

    echo 'is name: ' . $itemVersion->setLocale('is_IS')->getName() . "\n";
}

This throws error that the method setLocale() does not exists, as we are positioned in the class "BaseItemVersion.php", which does not have any BaseItemI18n.php methods.

Is there any way to solve this ?

Thanks.

Versioning of related objects is only possible for simple foreign keys. Relationships based on composite foreign keys cannot preserve relation versionning for now.

Since i18n adds complex foreign keys, the two won't work together.
