instance method `find_signed!`

Ruby on Rails 7.2.3

Since v6.1.7.10

Available in: v6.1.7.10 v7.0.10 v7.1.6 v7.2.3 v8.0.4 v8.1.2

Compare with:

find_signed!(signed_id, purpose: nil)

Works like find_signed, but will raise an ActiveSupport::MessageVerifier::InvalidSignature exception if the signed_id has either expired, has a purpose mismatch, is for another record, or has been tampered with. It will also raise an ActiveRecord::RecordNotFound exception if the valid signed id can’t find a record.

Examples

User.find_signed! "bad data" # => ActiveSupport::MessageVerifier::InvalidSignature

signed_id = User.first.signed_id
User.first.destroy
User.find_signed! signed_id # => ActiveRecord::RecordNotFound

Parameters

signed_id req
purpose key = nil
