Question

运行快速入门教程时，如果尝试将数据持久保存到Postgres数据库中，则在重新启动沙箱时，控制台中会出现分类帐标识符不匹配的情况。

在检查数据库之后，合同的信息仍然存在，但是ledger_entries为空。

步骤：

daml new quickstart quickstart-java
cd quickstart
daml build
daml sandbox dist/quickstart.dar --sql-backend-jdbcurl jdbc:postgresql://localhost/postgres?user=user&password=pass

以下是控制台上的输出：

HikariPool-1 - Start completed.
HikariPool-2 - Starting...
HikariPool-2 - Start completed.

这是不受控制的错误吗？还是保存在数据库中的数据不一致？

Answer 1

您可以将固定的分类帐ID作为命令行选项--ledgerid my-ledger传递到沙箱。

不过我明白你的意思。如果沙盒从数据库中获取分类帐ID，那将是更好的体验。

Daml沙箱持久性分类帐ID不匹配
