Mysql2::Error: 用户 'test' @'localhost' 对数据库 'depot_test' 的访问被拒绝

Question

我在这里有点难过。我创建了一个数据库，使用 depot_production 数据库没有问题。但是，最近每当我运行 rake 测试时，我都会收到一堆错误，例如

# Running tests:

EEEEEEEE

Finished tests in 0.031499s, 253.9763 tests/s, 0.0000 assertions/s.

1) Error:
test_should_create_product(ProductsControllerTest):
Mysql2::Error: Access denied for user 'test'@'localhost' to database 'depot_test'

奇怪的是我认为我的 database.yml 文件很好。每次我运行 db:migrate 时，我都会得到一个空行返回给我。我还添加了一个用户测试，但我认为这只将它添加到我的开发数据库中。我有点认为我的测试、生产和数据库不存在......

development:
adapter: mysql2
encoding: utf8
reconnect: false
database: depot_development
pool: 5
username: root
password: admin
socket: /tmp/mysql.sock

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
adapter: mysql2
encoding: utf8
reconnect: false
database: depot_test
pool: 5
username: test
password: testy
socket: /tmp/mysql.sock

production:
adapter: mysql2
encoding: utf8
reconnect: false
database: depot_production
pool: 5
username: prod
password: mypassword
socket: /tmp/mysql.sock

任何建议将不胜感激，谢谢。

感谢您在此陪伴我。我觉得我很接近，但有些奇怪。这就是我所做的。

因此，首先以 root 或从终端调用的任何您的 root 用户身份登录。

mysql -u root -p

CREATE DATABASE depot_test

CREATE USER 'test'@'localhost' IDENTIFIED BY 'mypass123';

USE depot_test

登录mysql后，授予用户test权限(记得修改密码)

GRANT ALL privileges on depot_test.* to test@localhost identified by 'mypass123';

FLUSH PRIVILEGES;

您需要在 database.yml 中将通行证更改为“mypass123”
