I have a model A that has many objects of model B using the association :has_many . When I create a new object of Model A, set its attributes, build related objects and check for objects that are not saved, it works fine. However, as soon as I try to save objects using save or save! I get the following back trace.
NoMethodError: undefined method `insert_record' for #<Array:0x000000052541f8> from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/associations/association_proxy.rb:154:in `send' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/autosave_association.rb:306:in `block in save_collection_association' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/associations/association_collection.rb:431:in `block in method_missing' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/associations/association_proxy.rb:216:in `block in method_missing' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/associations/association_proxy.rb:216:in `each' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/associations/association_proxy.rb:216:in `method_missing' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/associations/association_collection.rb:431:in `method_missing' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/autosave_association.rb:297:in `save_collection_association' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/autosave_association.rb:163:in `block in add_autosave_association_callbacks' from /usr/lib/ruby/gems/2.0.0/gems/activesupport-3.0.5/lib/active_support/callbacks.rb:415:in `_run_create_callbacks' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/callbacks.rb:281:in `create' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/persistence.rb:246:in `create_or_update' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/callbacks.rb:277:in `block in create_or_update' from /usr/lib/ruby/gems/2.0.0/gems/activesupport-3.0.5/lib/active_support/callbacks.rb:418:in `_run_save_callbacks' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/callbacks.rb:277:in `create_or_update' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/persistence.rb:39:in `save' ... 2 levels... from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/transactions.rb:240:in `block (2 levels) in save' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/transactions.rb:292:in `block in with_transaction_returning_status' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/connection_adapters/abstract/database_statements.rb:139:in `transaction' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/transactions.rb:207:in `transaction' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/transactions.rb:290:in `with_transaction_returning_status' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/transactions.rb:240:in `block in save' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/transactions.rb:251:in `rollback_active_record_state!' from /usr/lib/ruby/gems/2.0.0/gems/activerecord-3.0.5/lib/active_record/transactions.rb:239:in `save' from (irb):104 from /usr/lib/ruby/gems/2.0.0/gems/railties-3.0.5/lib/rails/commands/console.rb:44:in `start' from /usr/lib/ruby/gems/2.0.0/gems/railties-3.0.5/lib/rails/commands/console.rb:8:in `start' from /usr/lib/ruby/gems/2.0.0/gems/railties-3.0.5/lib/rails/commands.rb:23:in `<top (required)>' from /home/amitav/WMS/trunk/script/rails:6:in `require' from /home/amitav/WMS/trunk/script/rails:6:in `<top (required)>' from -e:1:in `load' from -e:1:in `<main>'
