Just updated DataMapper:
$ sudo gem install dm-core
Successfully installed extlib-0.9.13
Successfully installed addressable-2.1.1
Successfully installed dm-core-0.10.1
But now I'm getting this error....
migrations.rb:279:in `property_schema_statement': undefined method `quote_value' for # (NoMethodError)
Looks like I'm missing something....
sudo gem install data_objects
sudo gem install do_sqlite3
Had to remove the dpkgs too:
$ sudo apt-get remove libdataobjects-ruby1.8

That worked!
...but the hooks are giving me trouble again... and also my associations... DOH!
This is very strange... it appears that I cannot use the dm-aggregate sum function with an inherited class?
class Entry
include DataMapper::Resource
property :id,Serial
property :memorandum,String
property :status,Integer
property :fiscal_period_id,Integer
property :entered_on,Integer, :default => Time.now.to_i
has n, :ledgers
def credit_sum
# Does not work:
# !! Unexpected error while processing request:
# +options[:fields]+ entry #
# does not map to a property in Credit
#return Credit.sum(:amount, :entry_id => self.id)
# Works fine, but isn't it the same thing?
return Amount.sum(:amount, :type => 'Credit', :entry_id => self.id)
end
end
class Amount
include DataMapper::Resource
property :id,Serial
property :entry_id,Integer
property :type,Discriminator
property :amount,Integer
property :account_id,Integer
property :memorandum,String
property :currency_id,Integer
belongs_to :entry, :model => 'Entry', :child_key => [:entry_id, Integer]
def to_usd
return "%.2f" % (self.amount.to_r.to_d / 100)
end
def self.sum_usd
return self.entry.credits.sum(:amount)
end
end
class Credit < Amount; end
class Debit < Amount; end
Thought it might have been caused by some outdated libraries... but I've just cleared out some older libraries, still no luck.
