create_or_find_by!

rails latest stable - Class: ActiveRecord::Relation

create_or_find_by!(attributes, &block)

public

Like #create_or_find_by, but calls {create!}[rdoc-ref:Persistence::ClassMethods#create!] so an exception is raised if the created record is invalid.

# File activerecord/lib/active_record/relation.rb, line 228

        where(attributes).lock.find_by!(attributes)
      else
