Aggregates support for YAML
Reported by gioele | May 13th, 2010 @ 08:32 AM
dm-aggregates should support YAML-based models.
Currently, merb-admin used on a YAML-based database raises this exception:
undefined method `aggregate' for DataMapper::Adapters::YamlAdapter
A more complete backtrace:
undefined method `aggregate' for #<DataMapper::Adapters::YamlAdapter:0x7f06eed16090> - (NoMethodError)

Tagging this as suggestion.
I don't know if this specific feature will make it into dm-aggregates without someone who is interested in implementing it takes it on. Unfortunately this is the only request I've heard for adding aggregate support for YAML.
The DM2 query engine will likely provide aggregate support across all adapters, but it won't be ready for at least 6-12 months. In the meantime you can track it's development here:
