Important: #69084 - Adding Extbase Objects with NOT NULL columns has changed

See forge#69084


To better support databases that don't silently convert NULL values to an empty default value for database columns defined as NOT NULL the insertObject() method tries to determine the appropriate value for a column.

Extbase object properties that have a value of NULL will be skipped when preparing the record to enable the DBMS default value to be used. This behavior has not changed compared to TYPO3 CMS 7.4 but allows proper support for DBMS that are strict about NOT NULL columns by defining appropriate default values for properties in the models.

Example database schema:

CREATE TABLE tx_blogexample_domain_model_blog (
        title varchar(255) DEFAULT '' NOT NULL

Example model definition:

class Blog extends \TYPO3\CMS\Extbase\DomainObject\AbstractEntity {
         * The blog's title.
         * @var string
        protected $title = '';
