How to Query Products¶
Prerequisites¶
The Akeneo PIM project introduces services to help you manage your product objects.
The ProductQueryBuilder (PQB) allows you to build and execute complex queries with a simple API.
In Akeneo PIM, products can be stored and accessed through Doctrine ORM (EAV like model) or Doctrine MongoBDODM (Document model).
The PQB aims to abstract the used persistence storage to provide the same operations in both cases.
Instantiate a New Product Query Builder¶
The product query builder factory is a service, you can fetch it from the container.
// product query builder factory
$pqbFactory = $this->getContainer()->get('pim_catalog.query.product_query_builder_factory');
// returns a new instance of product query builder
$pqb = $pqbFactory->create(['default_locale' => 'en_US', 'default_scope' => 'ecommerce']);
Build a Query¶
Add filters:
$pqb
// You can filter on a field by id
->addFilter('categories.id', 'IN', [1, 2])
// Or filter using codes by adding the '.code' suffix
->addFilter('groups.code', 'IN', ['shirts'])
// filter on sku which is not localizable and not scopable
->addFilter('sku', 'CONTAINS', 'akeneo')
// filter on name which is localizable, the default locale is used, here 'en_US'
->addFilter('name', '=', 'My product name')
// filter on description which is localizable and scopable by using 'fr_FR' locale and 'mobile' scope
->addFilter('description', 'STARTS WITH', 'My desc', ['locale' => 'fr_FR', 'scope' => 'mobile'])
// filter on price
->addFilter('price', '>', ['data' => 70, 'currency' => 'EUR'])
// filter on a metric
->addFilter('weight', '<', ['data' => 1, 'unit' => 'KILOGRAM']);
Add sorters:
$pqb
->addSorter('family', 'ASC')
->addSorter('sku', 'DESC')
// to sort by completeness, the locale and the scope are expected, if not provided, the default ones are used
->addSorter('completeness', 'DESC', ['locale' => 'fr_FR', 'scope' => 'mobile']);
Execute the Query to Get a Cursor¶
It will return an AkeneoComponentStorageUtilsCursorInterface on the products collection.
This interface is “storage agnostic” and allows to iterate over the products in the same way for Doctrine ORM and MongoDBODM.
As it implements a Cursor, it avoids to load all the products in memory and uses an internal pagination to load them page per page.
We strongly advise to use this method to execute queries on products.
$productsCursor = $pqb->execute();
foreach ($productsCursor as $product) {
// your custom logic
}
Execute the Query (“classic” Doctrine mode)¶
Once filters and sorters are applied, you can still access the internal QueryBuilder to manipulate it before executing the query.
Then you can use a “classic” Doctrine execute (with custom hydration, etc),
// can be a `Doctrine\ORM\QueryBuilder` or `Doctrine\ODM\MongoDB\Query\Builder`
$queryBuilder = $pqb->getQueryBuilder();
// ...
// my custom code which manipulates the query builder
// ...
$queryBuilder->getQuery()->execute();
Warning
This should be reserved for special cases, when you want to use operations only available in the real storage mechanism (ex: MongoDB aggregate) or expressions not supported by the PQB.
Use the Product Repositories¶
You can also use different Product Repositories, which provide business queries.
/** implements Pim\Bundle\CatalogBundle\Repository\ProductRepositoryInterface */
$repository = $this->getContainer()->get('pim_catalog.repository.product');
/** implements Pim\Bundle\CatalogBundle\Repository\ProductCategoryRepositoryInterface */
$repository = $this->getContainer()->get('pim_catalog.repository.product_category');
Note
You can take a look on related interfaces to see the list of available methods
Use the Query Command¶
We introduced a new Command to execute a query through the Product Query Builder.
php app/console pim:product:query '[{"field":"completeness","operator":"=","value":"100","context":{"locale":"en_US","scope":"print"}}]' --page-size=20
By default this command returns a table formatted list of products on the standard output.
+-----+-------------+
| id | identifier |
+-----+-------------+
| 1 | AKNTS_BPXS |
| 2 | AKNTS_BPS |
| 3 | AKNTS_BPM |
| ... | ... |
+-----+-------------+
20 first products on 112 matching these criteria
You can use the option json-output to obtain a json result.
["AKNTS_BPXS","AKNTS_BPS","AKNTS_BPM"]
Use the Query Help Command¶
To help you know which filters are available for your installation, you can run the following command:
php app/console pim:product:query-help
Add a Custom Filter¶
Filters are tagged services (implementing FilterInterface), they are registered in a registry (QueryFilterRegistryInterface).
The PQB uses the registry to resolve the filter to use.
A filter can be used on a field (meaning on doctrine fields of product mapping, such as id, family, etc), or on an attribute (meaning on a product value, such as a sku, a name, etc).
To add your own filter, you need to create a class implementing Pim\Bundle\CatalogBundle\Query\Filter\FieldFilterInterface
and/or Pim\Bundle\CatalogBundle\Query\Filter\AttributeFilterInterface
and declare it as a service:
pim_catalog.doctrine.query.filter.boolean:
class: '%my_filter_class%'
arguments:
- ['pim_catalog_boolean']
- ['enabled']
- ['=']
tags:
- { name: 'pim_catalog.doctrine.query.filter', priority: 30 }
Here we define a boolean filter which supports ‘=’ operator and can be applied on the ‘enabled’ field or on an attribute with ‘pim_catalog_boolean’ type.
Add a Custom Sorter¶
Sorter implementation mechanism is very similar to the filter one: a registry, the interface PimBundleCatalogBundleQuerySorterSorterInterface to implement and a tagged service to declare as follows:
pim_catalog.doctrine.query.sorter.completeness:
class: '%pim_catalog.doctrine.query.sorter.completeness.class%'
tags:
- { name: 'pim_catalog.doctrine.query.sorter', priority: 30 }
