Installation

Install package via composer:

Add entry to bundles.php file:

Configuration class

To define how the import function should work, you need to create a configuration class.

Basic configuration class

In the simplest case it will contain only class of used entity.

Then register it as a service:

Fields definitions

If you want to change types of rendered fields, instead of using default ones, you have to override method in your import configuration. If name of field contains spaces, you should use underscores instead.

To avoid errors during data import, you can add here validation rules.

Matrix validation

This bundle provides two new validators.

1) DatabaseEntityUnique validator can be used to check if record data does not exist yet in database. 2) MatrixRecordUnique validator can be used to check duplication without checking database, just only matrix records values.

Names of fields should be the same as names of columns in your uploaded file. With one exception! If name contains spaces, you should use underscores instead.

Passing services to configuration class

If you want to pass some additional services to your configuration, just override constructor.

Then you will need to define this configuration class as a public service too.

Show & hide entity override column

If you want to hide/show an entity column that allows you to override entity default: true, you have to override this method in your import configuration.

Optimizing queries

If you use KnpLabs Translatable extension for your entity, probably you will notice increased number of queries, because of Lazy Loading.

To optimize this, you can use getEntityTranslationRelationName() method to pass the relation name to the translation.

Creating admin

Your admin class should implement AdminWithImportInterface and should contain one additional method.

Default controller

If you use default controller, no action is needed. Controller will be replaced automatically.

Custom controller

If you use your own custom controller, remember that this controller should:

• extend JG\SonataBatchEntityImportBundle\Controller\ImportCrudController
• or use JG\SonataBatchEntityImportBundle\Controller\ImportControllerTrait.

Additionally, if you want to automatically inject your import configuration class, remember to implement JG\SonataBatchEntityImportBundle\Controller\ImportConfigurationAutoInjectInterface and use method getImportConfiguration() from default controller.

Translations

This bundle supports KnpLabs Translatable behavior.

To use this feature, every column with translatable values should be suffixed with locale, for example:

• name:en
• description:pl
• title:ru

If suffix will be added to non-translatable entity, field will be skipped.

If suffix will be added to translatable entity, but field will not be found in translation class, field will be skipped.

Overriding templates

You have two ways to override templates globally:

• Configuration - just change paths to templates in your configuration file. Values in this example are default ones and will be used if nothing will be changed.

• Bundle directory - put your templates in this directory:

Importing data to array field

If your entity has an array field, and you want to import data from CSV file to it, this is how you can do it.

• Default separator is set to |.
• Only one-dimensional arrays are allowed.
• Keys are not allowed.
• IMPORTANT! There are limitations:
  • There is no possibility to import array with one empty element, for example:
  • ['']
  • [null]
  • But arrays with at least 2 such elements are allowed:
  • ['', '']
  • [null, null]
  • ['', null]
  • It is due of mapping CSV data to array:
  • Empty value in CSV is equal to []
  • If we have default separator, | value in CSV is equal to ['', '']

Entity

• Allowed entity field types:
  • json
  • array
  • simple_array

Import configuration

• You have to add a field definition with a custom ArrayTextType type. If you skip this configuration, TextType will be used as default.
• You can set here your own separator.
