protected function RegistrantStorageSchema::getSharedTableFieldSchema in RNG - Events and Registrations 8

Same name and namespace in other branches

1. 8.2 src/RegistrantStorageSchema.php \Drupal\rng\RegistrantStorageSchema::getSharedTableFieldSchema()
2. 3.x src/RegistrantStorageSchema.php \Drupal\rng\RegistrantStorageSchema::getSharedTableFieldSchema()

Gets the schema for a single field definition.

Entity types may override this method in order to optimize the generated schema for given field. While all optimizations that apply to a single field have to be added here, all cross-field optimizations should be via SqlContentEntityStorageSchema::getEntitySchema() instead; e.g., an index spanning multiple fields.

Parameters

\Drupal\Core\Field\FieldStorageDefinitionInterface $storage_definition: The storage definition of the field whose schema has to be returned.

string $table_name: The name of the table columns will be added to.

string[] $column_mapping: A mapping of field column names to database column names.

Return value

array The schema definition for the table with the following keys:

• fields: The schema definition for the each field columns.
• indexes: The schema definition for the indexes.
• unique keys: The schema definition for the unique keys.
• foreign keys: The schema definition for the foreign keys.

Throws

\Drupal\Core\Field\FieldException Exception thrown if the schema contains reserved column names or if the initial values definition is invalid.

    // This field was added to the registrant entity in a hook_update_N
