php - 警告 : Fixture creation for "catalog_items" failed "SQLSTATE[42S01]

Question

这是我遇到的错误。让我知道其根本原因是什么。

SQLSTATE[42000]: Syntax error or access violation: 1701 Cannot truncate a table referenced in a foreign key constraint (Proficiency.t_catalog_item_recommendations, CONSTRAINT fk_t_catalog_item_recommendations_catalog_item_id FOREIGN KEY (catalog_item_id) REFERENCES Proficiency.t_catalog_items (id))

每当我执行测试脚本时，它都会给出以下消息:

Warning: Fixture creation for "catalog_items" failed "SQLSTATE[42S01]: Base table or view already exists: 1050 Table 't_catalog_items' already exists" in /var/www/html/lib/Cake/TestSuite/Fixture/CakeTestFixture.php on line 244 Call Stack: 0.0018 262208 1. {main}() /var/www/html/app/webroot/test.php:0 0.1119 1133560 2.

Answer 1

The documentation说:

TRUNCATE cannot be used on a table that has foreign-key references from other tables, unless all such tables are also truncated in the same command.

所以这就是你必须做的。
