An entity marked with the flag readOnly=true is not tracked for updates anymore but it is still possible to insert or delete rows, as explained in the documentation.

The doctrine:schema:update command will still take the table into account to update the schema.

在问题的答案中“忽略 Doctrine2 实体运行架构管理器更新时” 有 3 个有效选项可以忽略架构更新中的实体。

schema_filter

schema_filter is not made to "filter" entity but to filter db table from doctrine awareness.

这是一个示例：
Assuming you manually create a table that is updated from a custom raw php cronjob called view_booking_by_customer_per_year, this table is not used by your code in your project but is used for data analysis.

这是一个典型的示例，您不希望每次更新架构时都生成这样的查询。

DROP TABLE view_booking_by_customer_per_year; // NO I DONT WANT THIS

So using schema_filter you can tell doctrine to ignore this table in his validation and update process.

Try to create a random table using raw sql and use doctrine:schema:validate. It will show database is not in sync error. 一旦将其放入 schema_filter 中，错误就不会再发生。

It work for doctrine:migration:diff and doctrine:schema:update

schema_ignore_class

但是，如果您想避免在数据库内生成实体，则可以从 Ernesto 的答案中的链接中找到：

schema_ignore_classes:
   - Reference\To\My\Class
   - Reference\To\My\OtherClass

仅从 Doctrine 2.7 版本开始工作。 您可以在这里找到完整的示例： 运行架构管理器更新时忽略 Doctrine2 实体

使用学说迁移

I strongly advise you to use doctrine:migration:diff then doctrine:migration:migrate instead of doctrine:schema:update to perform change on database. It's ok for local dev, but when in production it is a very bad practice.
