setting an atttribute in rails console - transaction rolled back - sql

Question

I've used this forum gem before and also been able to set the forem_admin to "true" using the console. However, this time it's rolling back the transaction when I try to save.
You can see below that I set the forem_admin to "true," saved it, it rolled back the transaction (which means it didn't save), I did "u" and it showed forem_admin = true but when I restarted the console it showed forem_admin = false.
If anyone's familiar with this gem, I think this forem_state attribute is new, so I'm wondering if anything's changed.
I'm not an SQL pro but one thing that looks funny to me is the line
"users"."id" != 5
I would have expected it to have been "users"."id" = 5 i.e. with no "!", because the id of the user "signuplinks" is 5.
this is a rails 3.2 app
update when I do u.errors after u.save, I'm getting this error message
#messages={:password=>["can't be blank"]}

Answer 1

actually, this was my own fault. Thanks to #muistooshort for pointing out problem probably is in model. I had included "password" in the validates_presence of validator which was stopping me from changing user details in the console (without including password)
