In rails, how can I find out what caused a .save() to fail, other than validation errors?
Try using the bang version save!
(with an exclamation mark at the end) and inspecting the resulting error.
If @user.save
(for example) returns false
, then just run this to get all the errors:
@user.errors.full_messages
Check all your callbacks.
I had a problem like this where I had and "after_validate" method that was failing after I had made a bunch of changes to the model. The model was valid but the "after_validate" was returning false, so if I used model.valid
it said true, but then if I saved it gave me validation errors (passed through from the after_validate callback). It was weird.
Look at the application trace and you should be able to see what line of code is raising the exception.
