Ensures the source value is made unique against an entity field.
The make_unique process plugin is typically used to make the entity id unique, ensuring that migrated entity data is preserved.
The make_unique process plugin has two required configuration keys, entity_type and field. It's typically used with an entity destination, making sure that after saving the entity, the field value is unique. For example, if the value is foo and there is already an entity where the field value is foo, then the plugin will return foo1.
The optional configuration key postfix which will be added between the number and the original value, for example, foo_1 for postfix: _. Note that the value of postfix is ignored if the value is not changed, if it was already unique.
The optional configuration key migrated, if true, indicates that an entity will only be considered a duplicate if it was migrated by the current migration.
Available configuration keys
- entity_type: The entity type.
- field: The entity field for the given value.
- migrated: (optional) A boolean to indicate that making the field unique only occurs for migrated entities.
- start: (optional) The position at which to start reading.
- length: (optional) The number of characters to read.
- postfix: (optional) A string to insert before the numeric postfix.
Examples:
process:
format:
-
plugin: machine_name
source: name
-
plugin: make_unique_entity_field
entity_type: filter_format
field: format
This will create a format machine name out the human readable name and make sure it's unique.
process:
format:
-
plugin: machine_name
source: name
-
plugin: make_unique_entity_field
entity_type: filter_format
field: format
postfix: _
migrated: true
This will create a format machine name out the human readable name and make sure it's unique if the entity was migrated. The postfix character is inserted between the added number and the original value.
