Hey,
I''m having an error when I try to save anything. Here is the output
from
the console. Anyone know why this would be happeing.
>> asset = Assetstatus.find(1)
=> #<Assetstatus:0x3bd3bf0 @attributes={"title"=>"Not
Started",
"id"=>"1", "deleted"=>nil}>
>> asset.deleted = 0
=> 0
>> asset.save
RuntimeError: Called id for nil, which would mistakenly be 4 -- if you

Thanks Jamis,
I should have seem that there. In the console I wasn''t setting my
User.current_user.id that I use. I''m getting a different error now
though.

Currently, it looks like it defaults to NULL, so that column is nil, which is causing the error when (I suspect) the locking module tries to increment it. That''s my theory, anyway. :) - Jamis> > from c:/Ruby/lib/ruby/gems/1.8/gems/activerecord-1.11.1/lib/ > active_record/locking.rb:33:in > `update_without_callbacks'' > from c:/Ruby/lib/ruby/gems/1.8/gems/activerecord-1.11.1/lib/ > active_record/callbacks.rb:274 > :in `update_without_timestamps'' > from c:/Ruby/lib/ruby/gems/1.8/gems/activerecord-1.11.1/lib/ > active_record/timestamp.rb:39: > in `update_without_user'' > from c:/Ruby/lib/ruby/gems/1.8/gems/activerecord-1.11.1/lib/ > usermonitor.rb:25:in `update'' > from c:/Ruby/lib/ruby/gems/1.8/gems/activerecord-1.11.1/lib/ > active_record/base.rb:1139:in > `create_or_update_without_callbacks'' > from c:/Ruby/lib/ruby/gems/1.8/gems/activerecord-1.11.1/lib/ > active_record/callbacks.rb:249 > :in `create_or_update'' > from c:/Ruby/lib/ruby/gems/1.8/gems/activerecord-1.11.1/lib/ > active_record/base.rb:965:in ` > save_without_validation'' > from c:/Ruby/lib/ruby/gems/1.8/gems/activerecord-1.11.1/lib/ > active_record/validations.rb:6 > 50:in `save_without_transactions'' > from c:/Ruby/lib/ruby/gems/1.8/gems/activerecord-1.11.1/lib/ > active_record/transactions.rb: > 128:in `save'' > from c:/Ruby/lib/ruby/gems/1.8/gems/activerecord-1.11.1/lib/ > active_record/transactions.rb: > 128:in `transaction'' > from c:/Ruby/lib/ruby/gems/1.8/gems/activerecord-1.11.1/lib/ > active_record/transactions.rb: > 93:in `transaction'' > from c:/Ruby/lib/ruby/gems/1.8/gems/activerecord-1.11.1/lib/ > active_record/transactions.rb: > 120:in `transaction'' > from c:/Ruby/lib/ruby/gems/1.8/gems/activerecord-1.11.1/lib/ > active_record/transactions.rb: > 128:in `save'' > from (irb):14 > > Any ideas, > Thanks in advance. > Eric > > Jamis Buck wrote: > > >> On Aug 19, 2005, at 2:45 PM, Eric Goodwin wrote: >> >> >>> Hey, >>> I''m having an error when I try to save anything.

Hey, Found out what is way. I have acts_as_versioned on and a field in the database called lock_version, which by default I had set to null. When locking.rb tried to update the field, it tried to add 1 to what was already in the database. This failed. I added in a check for null and if it is null then I make it 0 before I try to add 1 to it. Thanks, Eric Eric Goodwin wrote:> Thanks Jamis, > I should have seem that there.
