Hi everyone,
We are using DataMapper in our application. A few days ago the following
started happening: when we do a save or update on a DataMapper Resource,
we'll get the following:
undefined method `eager_load' for
#<DataMapper::Validations::ContextualValidators:0x69037c66>
I have tried to reproduce it with irb with no success. This is happening
way inside of a participant we're loading with ruote, using DataMapper
1.2.0. It seems to happen randomly, i.e., on a run it might happen on one
resource, on another run it might happen on a different one.
This is the definition of one of the offending Resources:
class Slot
include DataMapper::Resource
property :id, Serial
property :station, Integer
property :slotnumber, Integer
property :firmwareversion, String, :length=>255
property :hardwareversion, String, :length=>255
property :mechanicalversion, String, :length=>255
property :chargertype, String, :length=>255
property :statusledred, Boolean
property :statusledgreen, Boolean
property :statuscharging, Boolean
property :statusopen, Boolean
property :statusclosed, Boolean
property :statusoccupied, Boolean
property :lastalarm, String, :length=>4096
property :lastalarmtimestamp, DateTime
property :status, String, :length=>255
property :comments, Text
property :blocked, Boolean
end
Here is the backtrace:

The only DataMapper require is a single require 'data_mapper', we aren't
requiring dm-validations (or even mentioning it in the Gemfile). The
offending line in contextual_validators.rb is:
resource.__send__(:eager_load, properties_to_load)
I went in and added some logging for the resource and
properties_to_loadvariables:
resource: #<Slot @id=8 @station=1 @slotnumber=1 @firmwareversion=""
@hardwareversion="" @mechanicalversion="" @chargertype="TEST"
@statusledred=nil @statusledgreen=nil @statuscharging=false
@statusopen=false @statusclosed=false @statusoccupied=false @lastalarm=""
@lastalarmtimestamp=nil @status="FREE" @comments=<not loaded>
@blocked=false>
properties_to_load:[#<DataMapper::Property::Text @model=Slot
@name=:comments>, #<DataMapper::Property::Text @model=Slot @name=:comments>]
Any ideas? Thanks!
