Add @observer_ After model, the database route fails and cannot be written

[zhaoliguangLFL]

I have tested adding and not adding observer and found that adding @observer_ Cannot write to database after model

I set multiple data and did not set the default database, use db router

Soory for the slow response on this.

I see so you do not have a default DB. That is an interesting issue.

In the rest of your server do you expliclty set the DB to use or do you let django auto select it?
