Aggregates support for YAML #4

Closed solnic closed 11 years ago

solnic commented 13 years ago

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:

I’d also like to see aggregate support for the YAML adapter.

I'm going to mark this as closed, since it won't make it into DM1. The aggregate component is built into DM2, and will be handled there.
