DBALException when updating schema

[jstoeffler]

Using Symfony 2.6 with this wonderful bundle, I tried to update the database, and I get the following error:

[Doctrine\DBAL\DBALException]                                                                                                                                                                            
An exception occurred while executing 'ALTER TABLE wp_term_taxonomy ADD CONSTRAINT FK_C4D725F53D8E604F FOREIGN KEY (parent) REFERENCES wp_terms (term_id)':                                              
SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`crp-img`.`#sql-31c0_167`, CONSTRAINT `FK_C4D725F53D8E604F` FOREIGN KEY (`parent`) REFERENCES `wp_terms` (`term_id`))                      

It seems that Doctrine tries to override the Wordpress constraint, or am I missing something? It did perform a lot of updates on the Wordpress tables with tables when I first ran the update.

It also tries to update those:

ALTER TABLE wp_links CHANGE link_notes link_notes MEDIUMTEXT NOT NULL;
ALTER TABLE wp_term_taxonomy ADD CONSTRAINT FK_C4D725F53D8E604F FOREIGN KEY (parent) REFERENCES wp_terms (term_id);
CREATE INDEX IDX_C4D725F53D8E604F ON wp_term_taxonomy (parent);
ALTER TABLE wp_users CHANGE user_pass user_pass VARCHAR(64) DEFAULT '' NOT NULL, CHANGE user_registered user_registered DATETIME DEFAULT '1970-01-01 00:00:00' NOT NULL, CHANGE user_activation_key user_activation_key VARCHAR(60) DEFAULT '' NOT NULL;
ALTER TABLE wp_usermeta CHANGE umeta_id umeta_id INT UNSIGNED AUTO_INCREMENT NOT NULL, CHANGE user_id user_id BIGINT UNSIGNED DEFAULT NULL;
ALTER TABLE wp_usermeta ADD CONSTRAINT FK_F3914E8EA76ED395 FOREIGN KEY (user_id) REFERENCES wp_users (ID);

Is this normal? Is there a proper way to update the schema with this bundle?

Same problem

[jstoeffler]

It seems to work using a different entity manager for the bundle and the app. So your app will ignore the WP entities.

hi @jstoeffler

Have you an example of the good configuration to work with different entity manager, i try this, but it don't work

`` doctrine: dbal: default_connection: symfony connections: symfony: driver: pdo_mysql host: '%database_host%' port: '%database_port%' dbname: '%database_name_symfony%' user: '%database_user_symfony%' password: '%database_password_symfony%' charset: UTF8 wordpress: driver: pdo_mysql host: '%database_host%' port: '%database_port%' dbname: '%database_name_wordpress%' user: '%database_user_wordpress%' password: '%database_password_wordpress%' charset: UTF8

orm:
    default_entity_manager: default
    entity_managers:
        symfony:
            connection: symfony
            mappings:
                AppBundle:  ~
        wordpress:
            connection: wordpress
            mappings:
                EkinoWordpressBundle: ~

``

The problem could come from

default_entity_manager: default

You could replace it by:

default_entity_manager: symfony

or rename the symfony em to "default".

Also I don't use different DB connections, it shouldn't be a problem, but is it necessary?

Hi -- I'm having the same problem. Has anyone found a workaround other than using a different entity manager? When I use a different entity manager, I am unable to use the entities from the ekino bundle as foreign keys in my symfony entity manager. (Or has someone found a way to do that successfully?) Thank you!
