问题描述
我正在使用/设置配置如下的Symfony DoctrineMigrationsBundle v2.2
:
doctrine_migrations:
name: 'My Migrations'
migrations_paths:
'DoctrineMigrations': '%kernel.project_dir%/src/Migrations'
storage:
table_storage:
table_name: 'migrations'
version_column_name: 'version'
version_column_length: 1024
executed_at_column_name: 'executed_at'
# Seems not to be supported:
# Unrecognized option "execution_time_column_name" under "doctrine_migrations.storage.table_storage"
# execution_time_column_name: 'execution_time'
organize_migrations: false
# custom_template: ~
all_or_nothing: false
RDBMS是MysqL v8
,在Ubuntu桌面v20.04
上(本地)运行:
$ MysqL --version
MysqL Ver 8.0.22-0ubuntu0.20.04.2 for Linux on x86_64 ((Ubuntu))
DEFAULT_CHaraCTER_SET_NAME
是utf8mb4
,DEFAULT_COLLATION_NAME
是utf8mb4_unicode_ci
:
SELECT
`DEFAULT_CHaraCTER_SET_NAME`,`DEFAULT_COLLATION_NAME`
FROM
`informatION_SCHEMA`.`SCHEMATA`
WHERE
`SCHEMA_NAME` = "payment"
;
+----------------------------+------------------------+
| DEFAULT_CHaraCTER_SET_NAME | DEFAULT_COLLATION_NAME |
+----------------------------+------------------------+
| utf8mb4 | utf8mb4_unicode_ci |
+----------------------------+------------------------+
在玩配置时,我以某种方式创建了两个迁移表(我多次更改了doctrine_migrations.storage.table_storage.table_name
)...现在,在完成配置之后,我想再次进行设置从头开始。因此,我删除了两个迁移表,然后重新开始。但是现在我得到以下错误:
$ ./bin/console doctrine:migrations:status
...
In AbstractMysqLDriver.PHP line 106:
An exception occurred while executing 'CREATE TABLE migrations (version VARCHAR(1024) NOT NULL,executed_at DATETIME NOT NULL COMMENT '(DC2Type:datetime_immutable)',PRIMARY KEY(version)) DEFAULT CHaraCTER
SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE = InnoDB':
sqlSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 3072 bytes
In PDOConnection.PHP line 43:

In PDOConnection.PHP line 41:
sqlSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 3072 bytes
我尝试减少doctrine_migrations.storage.table_storage.version_column_length
,但是随后我又遇到了另一个错误:
$ ./bin/console doctrine:migrations:status
...
In BaseNode.PHP line 348:
Invalid configuration for path "doctrine_migrations.storage.table_storage.version_column_length": The minimum length for the version column is 1024.
In ExprBuilder.PHP line 189:
The minimum length for the version column is 1024.
如何正确设置并生成migrations
表?
解决方法
这不是(干净的)解决方案,但至少是一种解决方法:
删除配置doctrine_migrations.storage.table_storage.version_column_length
使其再次起作用。生成的配置如下:
$ bin/console debug:config doctrine_migrations
...
Current configuration for extension with alias "doctrine_migrations"
