# PCM Metadata Bundle
|
|
|
|
Easily add metadata to a Symfony entity via the use of a key-value interface.
|
|
|
|
# Usage
|
|
1. Use the `MetadataTrait` inside an entity:
|
|
```php
|
|
class MyEntity
|
|
{
|
|
use MetadataTrait;
|
|
}
|
|
```
|
|
2. Create and execute a new migration. The trait adds a `metadata` database field and as such we need to create a migration.
|
|
3. Access the metadata object with the readonly property `metadata`:
|
|
```php
|
|
$entity->metadata->set("name", "PCM");
|
|
$entity->metadata->get("name"); // "PCM"
|
|
$entity->metadata->isSet("name"); // true
|
|
```
|
|
|
|
> Like setting a property normally, setting metadata values will not automatically update the database.
|
|
You must call `flush()` from the `EntityManager` as usual when you wish to persist data.
