"undefined method 'name' for false:FalseClass"

Question

All functional tests for my object "Line" fail. I don't even know where to start debugging this:

21) Error: test_should_update_line(LinesControllerTest): NoMethodError: undefined method name' for false:FalseClass c:/Ruby193/lib/ruby/gems/1.9.1/gems/factory_girl-4.0.0/lib/factory_girl/decl aration/static.rb:11:in==' c:/Ruby193/lib/ruby/gems/1.9.1/gems/activerecord-3.2.3/lib/active_record/att ribute_methods/write.rb:57:in convert_number_column_value' c:/Ruby193/lib/ruby/gems/1.9.1/gems/activerecord-3.2.3/lib/active_record/att ribute_methods/write.rb:50:intype_cast_attribute_for_write' c:/Ruby193/lib/ruby/gems/1.9.1/gems/activerecord-3.2.3/lib/active_record/att ribute_methods/serialization.rb:88:in type_cast_attribute_for_write' c:/Ruby193/lib/ruby/gems/1.9.1/gems/activerecord-3.2.3/lib/active_record/att ribute_methods/write.rb:38:inwrite_attribute' c:/Ruby193/lib/ruby/gems/1.9.1/gems/activerecord-3.2.3/lib/active_record/att ribute_methods/dirty.rb:67:in write_attribute' c:/Ruby193/lib/ruby/gems/1.9.1/gems/activerecord-3.2.3/lib/active_record/att ribute_methods/write.rb:14:inport=' c:/Ruby193/lib/ruby/gems/1.9.1/gems/factory_girl-4.0.0/lib/factory_girl/attr ibute_assigner.rb:16:in block (2 levels) in object' c:/Ruby193/lib/ruby/gems/1.9.1/gems/factory_girl-4.0.0/lib/factory_girl/attr ibute_assigner.rb:15:ineach' c:/Ruby193/lib/ruby/gems/1.9.1/gems/factory_girl-4.0.0/lib/factory_girl/attr ibute_assigner.rb:15:in block in object' c:/Ruby193/lib/ruby/gems/1.9.1/gems/factory_girl-4.0.0/lib/factory_girl/attr ibute_assigner.rb:14:intap' c:/Ruby193/lib/ruby/gems/1.9.1/gems/factory_girl-4.0.0/lib/factory_girl/attr ibute_assigner.rb:14:in object' c:inobject' c:/Ruby193/lib/ruby/gems/1.9.1/gems/factory_girl-4.0.0/lib/factory_girl/stra tegy/create.rb:9:in result' c:/Ruby193/lib/ruby/gems/1.9.1/gems/factory_girl-4.0.0/lib/factory_girl/fact ory.rb:42:inrun' c:/Ruby193/lib/ruby/gems/1.9.1/gems/factory_girl-4.0.0/lib/factory_girl/fact ory_runner.rb:23:in block in run' c:/Ruby193/lib/ruby/gems/1.9.1/gems/activesupport-3.2.3/lib/active_support/n otifications.rb:125:ininstrument' c:/Ruby193/lib/ruby/gems/1.9.1/gems/factory_girl-4.0.0/lib/factory_girl/fact ory_runner.rb:22:in run' c:/Ruby193/lib/ruby/gems/1.9.1/gems/factory_girl-4.0.0/lib/factory_girl/stra tegy_syntax_method_registrar.rb:19:inblock in define_singular_strategy_method'

Answer 1

Looks like you're passing @line to update where you should be passing @line.id. Try changing that to:

put :update, id: @line.id, line: { description: @line.description }
