Foreign key constraint error - cannot seem to resolve this
April 29, 2007, 06:19:44 am
Been going crazy trying to debug this. I moving from a local installation where the site was developed to my production environment. I am using the latest 1.7 beta of Civicrm.

Getting this error:

Sorry. A non-recoverable error has occurred.
Database Error Code: Cannot add or update a child row: a foreign key constraint fails (`jmayer_bvcivicrm/civicrm_contact`, CONSTRAINT `FK_civicrm_contact_domain_id` FOREIGN KEY (`domain_id`) REFERENCES `civicrm_domain` (`id`)), 1452

Return to CiviCRM menu.

Stephen / JMSobe:

  • Did u load civicrm_data.mysql OR civicrm_generated.mysql into your mysql database
  • Do you have the below DEFINE in your civicrm.settings.php file

    define('CIVICRM_DOMAIN_ID' , 1 );

    I suspect this is the cause, since your domain_id value is 0 in the mysql statements

Donald,


I have am using civicrm_data.mysql. I don't have any real data yet in CiviCrm so I will reload the data if necessary using the generated file if that will fix my problem. My domain id is

define('CIVICRM_DOMAIN_ID' , 0 );

Try changing your civicrm.settings.php domain ID to 1 (which is the default for a single domain install). I don't think 0 works. Not sure how you got 0 as your value ???

define('CIVICRM_DOMAIN_ID' , 1 );

You might want to drop the DB and reload civicrm_41.mysql and civicrm_data.mysql after making this change and before accessing the site - as the 0 setting might have left some undesired entries in the DB.

I too was getting this foreign key constraint error. However, my civicrm.settings.php has define('CIVICRM_DOMAIN_ID' , 1 ); I used civicrm_generated.mysql, (and got a similar foreign key error when running the script, which I ignored unfortunately).

Anyway, based on your advice, I dropped my tables, reimported civicrm_41.mysql followed by civicrm_data.mysql, and everything is now running fine.

I'm thinking there's a problem with the 'generated' version of the data import script. I'm not savvy enough with MySQL to figure out what that is, though.
