Description (last modified by )
I am running into this error when I try to test an app using a MySQL database. I get an IntegrityError(1215, 'Cannot add foreign key constraint')" while creating the tables.
What is happenning is this: I have a model called SyncLog which has a foreign key to another model called UserEmployee. The error happens when this foreign key is added.
I checked the history of queries run by Django while creating the table and the results are below shown. What I can see is that Django starts creating the SyncLog table before the UserEmployee table and, because that table does not exist yet, the creation fails. I would suppose that there is a bug when determining the dependencies between models in order to determine the order the tables should be created.
CREATE DATABASE `test_compras` set autocommit=0 set autocommit=1 SET SQL_AUTO_IS_NULL = 0 SHOW FULL TABLES CREATE TABLE `django_migrations` (`id` integer AUTO_INCREMENT NOT NULL PRIMARY KEY, `app` varchar(255) NOT NULL, `name` varchar(255) NOT NULL, `applied` datetime(6) NOT NULL) SELECT engine FROM information_schema.tables WHERE table_name = \django_migrations\ SELECT `django_migrations`.`app`, `django_migrations`.`name` FROM `django_migrations` SHOW FULL TABLES set autocommit=0 CREATE TABLE `e89_syncing_synclog` (`id` integer AUTO_INCREMENT NOT NULL PRIMARY KEY, `user_id` integer NOT NULL, `timestamp` datetime(6) NOT NULL, `identifier` varchar(100) NOT NULL) SELECT engine FROM information_schema.tables WHERE table_name = \e89_syncing_synclog\ CREATE TABLE `e89_tools_keyvaluestore` (`id` integer AUTO_INCREMENT NOT NULL PRIMARY KEY, `key` varchar(255) NOT NULL UNIQUE, `value` longtext NOT NULL) SELECT engine FROM information_schema.tables WHERE table_name = \e89_tools_keyvaluestore\ CREATE TABLE `e89_push_messaging_device` (`id` integer AUTO_INCREMENT NOT NULL PRIMARY KEY, `owner_id` integer NOT NULL, `registration_id` varchar(200) NOT NULL, `platform` varchar(30) NOT NULL, UNIQUE (`registration_id`, `platform`)) SELECT engine FROM information_schema.tables WHERE table_name = \e89_push_messaging_device\ CREATE TABLE `e89_beta_testing_betatester` (`id` integer AUTO_INCREMENT NOT NULL PRIMARY KEY, `email` varchar(255) NOT NULL UNIQUE, `name` varchar(255) NOT NULL, `platform` varchar(30) NULL, `udid` varchar(255) NULL, `phone` varchar(20) NOT NULL, `token` varchar(50) NOT NULL) SELECT engine FROM information_schema.tables WHERE table_name = \e89_beta_testing_betatester\ CREATE TABLE `e89_beta_testing_iphonebetaapp` (`id` integer AUTO_INCREMENT NOT NULL PRIMARY KEY, `plist_url` varchar(300) NULL, `ipa` varchar(100) NOT NULL, `plist` varchar(100) NOT NULL) SELECT engine FROM information_schema.tables WHERE table_name = \e89_beta_testing_iphonebetaapp\ ALTER TABLE `e89_syncing_synclog` ADD CONSTRAINT `e89_syncing_user_id_670069ad1cf9eaae_fk_accounts_useremployee_id` FOREIGN KEY (`user_id`) REFERENCES `accounts_useremployee` (`id`) rollback set autocommit=1
The stacktrace I get is pasted below:
IntegrityError: (1215, 'Cannot add foreign key constraint') File "raven/contrib/django/management/__init__.py", line 41, in new_execute File "django/core/management/base.py", line 444, in execute File "django/core/management/commands/migrate.py", line 179, in handle File "django/core/management/commands/migrate.py", line 317, in sync_apps File "django/db/backends/utils.py", line 64, in execute File "django/db/utils.py", line 97, in __exit__ File "django/db/backends/utils.py", line 62, in execute File "django/db/backends/mysql/base.py", line 124, in execute File "MySQLdb/cursors.py", line 205, in execute File "MySQLdb/connections.py", line 36, in defaulterrorhandler
I ran the same test with Django 1.7.9 and it worked fine.
I am using Sentry to monitor exceptions and I have their full stack trace with variable values and all. I will not paste it here because it's too long and kind of hard to read but I will attach it as a separate file because I believe it could help identifying the cause of this bug.

Json with the stacktrace generated by Sentry. It contains variable values at the moment the exception occurred.
