I am trying to upgrate rails from 3.0 to 3.1, while updating rails version I am getting following error
rake aborted! undefined method `sanitize_limit' for #<ActiveRecord::Relation:0x2aaaad35d720> /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/relation.rb:460:in `method_missing' /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/relation/query_methods.rb:208:in `build_arel' /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/relation/query_methods.rb:196:in `arel' /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/relation.rb:112:in `to_a' /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/relation/finder_methods.rb:376:in `find_first' /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/relation/finder_methods.rb:122:in `first' Error is occurred at the execution of following statement: test = where(search_column_name => attributes[search_column_name]).first I found following solution on internet: https://github.com/rails/rails/issues/1974 Hence updated to: test = where(search_column_name => attributes[search_column_name]).all.to_a.first ...and this statement started working fine. But, find_by_name() is still failing with the same error. for eg. the below statement is not always working. test_lookup = find_by_identifier(lookup_str) || find_by_name(lookup_str) || find_by_abbreviation(lookup_str) statement is called under a function, defined in a model: def self.lookup(lookup_str) return nil if lookup_str.blank? test_lookup = find_by_identifier(lookup_str) || find_by_name(lookup_str) || find_by_abbreviation(lookup_str) return test_lookup if test_lookup.present? end It throws following error: rake aborted! undefined method `sanitize_limit' for #<ActiveRecord::Relation:0x2aaaacf14010> /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/relation.rb:460:in `method_missing' /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/relation/query_methods.rb:208:in `build_arel' /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/relation/query_methods.rb:196:in `arel' /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/relation.rb:112:in `to_a' /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/relation/finder_methods.rb:376:in `find_first' /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/relation/finder_methods.rb:122:in `first' /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/relation/finder_methods.rb:263:in `send' /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/relation/finder_methods.rb:263:in `find_by_attributes' /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/base.rb:1074:in `send' /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/base.rb:1074:in `method_missing' What should be the alternative for find_by_name() [i.e. find_by_attribute()]??? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
