Record is not saved to database

Hi, all!

Maybe a noob question, sorry, but I'm really stuck with this. I have 2 models with has_many and belongs_to associations. class Transaction < ActiveRecord::Base   has_many :bonuses, :class_name => 'TransactionBonus' end class TransactionBonus < ActiveRecord::Base   belongs_to :transaction end

The problem is that I cannot save TransactionBonus record to the database - it's simply doesn't do anything! I have another models in my application, and all of them are saved just fine TransactionBonus is the only exception

Table structure matches exactly the model records: CREATE TABLE IF NOT EXISTS `transaction_bonuses` (   `id` int(11) NOT NULL auto_increment,   `transaction_id` int(11) NOT NULL,   `taken_bonus` float default NULL,   `collected_bonus` float default NULL,   `final_sum` float default NULL,   `created_at` datetime default NULL,   `updated_at` datetime default NULL,   PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

Here is my irb console output with test records:

transaction=Transaction.find(1)

=> #<Transaction id: 1, card_account_id: 1, created_at: "2008-09-01 13:48:10", updated_at: "2008-09-01 13:48:10">

transaction.bonuses

=>

bonus=transaction.bonuses.create(:transaction_id => 1, :final_sum => 99)

=> #<TransactionBonus id: nil, transaction_id: 1, final_sum: 99.0, created_at: nil, updated_at:

transaction.bonuses

=> [#<TransactionBonus id: nil, transaction_id: 1, final_sum: 99.0, created_at: nil, updated_at:

]

bonus.save

=> #<Transaction id: 1, card_account_id: 1, created_at: "2008-09-01 13:48:10", updated_at: "2008-09-01 13:48:10">

bonus

=> #<TransactionBonus id: nil, transaction_id: 1, final_sum: 99.0, created_at: nil, updated_at:

After that I have tried to initialize TransactionBonus record directly, but no success:

>> bonus = TransactionBonus.create( :transaction_id => 1 ) => #<TransactionBonus id: nil, transaction_id: 1, final_sum: nil, created_at: nil, updated_at: nil>

>> bonus => #<TransactionBonus id: nil, transaction_id: 1, final_sum: nil, created_at: nil, updated_at: nil>

>> bonus.save => #<Transaction id: 1, card_holder_id: 0, card_account_id: 1, created_at: "2008-09-01 13:48:10", updated_at: "2008-09-01 13:48:10">

>> bonus => #<TransactionBonus id: nil, transaction_id: 1, final_sum: nil, created_at: nil, updated_at: nil>

Please, note id: nil for the bonus var, it means that the record is not saved to the database.

This is really mysterious for me...

Don't call your model transaction - you're overriding some internal activerecord methods.

Try using create! to see if the problem is with validation or due to a false-returning pre-save callback.
