What are some common Active Record errors I might encounter in Ruby on Rails?
Some common Active Record errors include 'RecordNotFound', 'Validation failed', and 'ActiveRecord::RecordNotUnique'.
Can you explain what 'RecordNotFound' means?
'RecordNotFound' occurs when you try to find a record by its ID, but no record exists with that ID.
What about 'Validation failed'? What causes that?
'Validation failed' happens when a model's validations do not pass, such as when required fields are missing.
How can I handle these errors in my application?
You can handle these errors using rescue blocks or by checking for errors before saving records.
