Magento. How to link store_id to the attribute in the custom EAV Model - magento

Question

I am using this tutorial on adding new EAV Model in Magento:
http://inchoo.net/ecommerce/magento/creating-an-eav-based-models-in-magento/
Everything works fine except all my attributes are saving with "store_id = 0" when I do this part of code:
$phonebookUser = Mage::getModel('inchoo_phonebook/user');
$phonebookUser->setFristname('John');
$phonebookUser->save();
I am wondering is there any clear way to set store ID on save EAV Entity Attributes.
Thanks.

Answer 1

You can only set values for a specific store only after you added the values for store id 0.
Here is an example.
//create default values
$phonebookUser = Mage::getModel('inchoo_phonebook/user');
$phonebookUser->setFristname('John');
$phonebookUser->save();
//remember the id of the entity just created
$id = $phonebookUser->getId();
//update the name for store id 1
$phonebookUser = Mage::getModel('inchoo_phonebook/user')
->setStoreId(1)
->load($id); //load the entity for a store id.
$phonebookUser->setFristname('Jack'); //change the name
$phonebookUser->save(); //save

I have override the functions in my resource model to work with store_id and it is worked for me but I suggest that this is not the best solution.
protected function _saveAttribute($object, $attribute, $value)
{
$table = $attribute->getBackend()->getTable();
if (!isset($this->_attributeValuesToSave[$table])) {
$this->_attributeValuesToSave[$table] = array();
}
$entityIdField = $attribute->getBackend()->getEntityIdField();
$data = array(
'entity_type_id' => $object->getEntityTypeId(),
$entityIdField => $object->getId(),
'attribute_id' => $attribute->getId(),
'store_id' => $object->getStoreId(), //added this
'value' => $this->_prepareValueForSave($value, $attribute)
);
$this->_attributeValuesToSave[$table][] = $data;
return $this;
}
protected function _getLoadAttributesSelect($object, $table)
{
$select = $this->_getReadAdapter()->select()
->from($table, array())
->where($this->getEntityIdField() . ' =?', $object->getId())
->where('store_id in (?)', array($object->getStoreId(), 0)); //added this
return $select;
}
also I have added this code to the constructor of my entity model:
if (Mage::app()->getStore()->isAdmin()) {
$this->setStoreId(Mage::app()->getRequest()->getParam('store', 0));
}
else{
$this->setStoreId(Mage::app()->getStore()->getId());
}

Override the _getDefaultAttributes() method in your resource model like this:
protected function _getDefaultAttributes()
{
$attributes = parent::_getDefaultAttributes();
$attributes[] = "store_id";
return $attributes;
}
This should work if you have only one value for store_id per your model's entity.
