Django：通过添加m2m导致“当前事务中止，命令被忽略，直到事务块结束”

[英]Django: Added m2m via through causes 'current transaction is aborted, commands ignored until end of transaction block'

原文 2013-08-26 18:44:29 2 1 python/ django/ postgresql/ transactions

I am trying to add an m2m relationship via a through table and, out of the blue, am encountering the following error: 我试图通过直通表添加m2m关系，并且突然出现了以下错误：

'current transaction is aborted, commands ignored until end of transaction block' “当前事务中止，命令被忽略，直到事务块结束”

There are 2 odd issues about this. 有两个奇怪的问题。 The first is that, I've successfully migrated/synced all of my relevant apps. 首先是，我已经成功迁移/同步了所有相关应用。 The second is that both the associated models and the model in question (AddedFeature) successfully save into the database even if the error is thrown. 第二个原因是，即使引发错误，关联的模型和相关的模型（AddedFeature）也会成功保存到数据库中。 That is, even though the transaction is aborted, the AddedFeature instance is saved to the DB. 也就是说，即使事务中止，AddedFeature实例也将保存到数据库。

Just to reiterate - refreshing my DB and remigrating/resyncing did not help solve the issue. 只是重申一下-刷新数据库和重新迁移/重新同步并没有帮助解决问题。

Look for the problem that happened before this error. 查找此错误之前发生的问题。 Your code, or code you're using, is ignoring a database error. 您的代码或您正在使用的代码正在忽略数据库错误。 So the next operation fails. 因此，下一个操作失败。

You need to look in the database and/or application logs to find the previous problem. 您需要查看数据库和/或应用程序日志以查找先前的问题。 Then determine what part of your app's code is swallowing a database exception without logging it and aborting the transaction. 然后确定应用程序代码的哪一部分吞没了数据库异常，而没有记录它并中止了事务。

Setting log_statement = 'all' in postgresql.conf can be useful for this. 在postgresql.conf设置log_statement = 'all'对此很有用。
