我正在用MySQL數(shù)據(jù)庫構(gòu)建一個django應(yīng)用程序。當(dāng)我第一次運行“python manage.py migrate”時，一些表創(chuàng)建得很好，然后出現(xiàn)一些錯誤。出現(xiàn)的錯誤是：django.db.utils.IntegrityError: (1215, 'Cannot add foreign key

constraint')

當(dāng)我運行這個MySQL命令時-SHOW ENGINE INNODB STATUS\G,

我明白了&gt；&gt2015-02-17 14:33:17 7f10891cf700 Error in foreign key constraint of table movie_store/#sql-4f1_66:
