Question

All of a sudden, I cannot save any models in my PostgreSQL database in Rails. Retrieving data works fine.

m = Model.find(1)
m.save
=> false

When I switched to another database, it is fine. There is no entry in the Rails log.

What could cause this behavior? Is the database corrupt? Is the disk dying? I tried rebooting but that did not help.

How can you check the integrity of the database (I have pgAdmin III installed)? Do I need to do some maintenance? How to figure out what the problem is?

Working in Ubuntu 11.04, Rails 3.0.7 and PostgreSQL 8.3.

Answer 1

Have you added any validations since that object was created? Try this:

> m = Model.find(1)
> m.valid?
> m.errors.full_messages

If something was wrong with your PostgreSQL database you’d probably be seeing exceptions and read errors.
