The CustomIndexBundle allows create index for doctrine entities using annotation with entity definition and console command.
CustomIndexBundle requires Symfony 2.1 or higher. Now work only with PostgreSQL.
Require the bundle in your composer.json
file:
{
"require": {
"intaro/custom-index-bundle": "~0.2.2",
}
}
Install the bundle:
$ composer update intaro/custom-index-bundle
Register the bundle in AppKernel
:
// app/AppKernel.php
public function registerBundles()
{
$bundles = array(
//...
new Intaro\CustomIndexBundle\IntaroCustomIndexBundle(),
);
//...
}
If your project have many schemas in single database and command must generate custom indexes only for one schema then add in your config.yml
:
intaro_custom_index:
search_in_all_schemas: false
Default value of search_in_all_schemas
is true
.
If you have different entities in different schemas and you need to update custom indexes in all schemas at once then you must set search_in_all_schemas
to true
or omit this config.
If you have database with only public schema then search_in_all_schemas
value doesn't matter.
- Add annotation in your entity
<?php
namespace Acme\MyBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Intaro\CustomIndexBundle\Annotations as CustomIndexAnnotation
/**
* @ORM\Table(name="my_entity")
* @ORM\Entity()
* @CustomIndexAnnotation\CustomIndexes(indexes={
* @CustomIndexAnnotation\CustomIndex(columns="my_property1"),
* @CustomIndexAnnotation\CustomIndex(columns={"lower(my_property1)", "lower(my_property2)"})
* })
*/
class MyEntity
{
/**
* @ORM\Column(type="string", length=256)
*/
protected $myProperty1;
/**
* @ORM\Column(type="string", length=256)
*/
protected $myProperty2;
}
Available CustomIndex attributes:
columns
- array of the table columnsname
- index name (default ='i_cindex_<md5 hash from all CustomIndex attributes>'
).unique
- index is unique (default = false).using
- corresponds toUSING
directive in PostgreSQLCREATE INDEX
command.where
- corresponds toWHERE
directive in PostgreSQLCREATE INDEX
command.
Required only columns
attribute.
- Use
intaro:doctrine:index:update
command for update db.
php app/console intaro:doctrine:index:update
You may use dump-sql
parameter for dump sql with DROP/CRATE INDEX
commands
php app/console intaro:doctrine:index:update --dump-sql
Create index using pg_trgm
extension:
@CustomIndexAnnotation\CustomIndex(columns="lower(my_column) gist_trgm_ops", using="gist")
Create unique index using PostgreSQL functions:
@CustomIndexAnnotation\CustomIndex(columns={"lower(my_column1)", "nullif(true, not my_column2 isnull)"}, unique=true)
Create partial index:
@CustomIndexAnnotation\CustomIndex(columns={"site_id"}, where="product_id IS NULL")
