Mongoid: How to chain eager loading?

I have three models: Project, LineItem, and Spec

Project has many line items Project has many specs

I figured out how to eager load Project in a LineItem query:

LineItem.all.includes(:project)

but I can't seem to be able to get the eager loaded projects to also eager load their specs. How does one chain such eager loads in Mongoid?

Thank you!

Have a look at Rails doc here

LineItem.all.includes(:project => :specs)
# or
LineItem.all.includes({project: :specs})

If it is so important to be eager loading, perhaps you should consider embedding those specs. I know this is not an answer to your question, but it may be a better solution.
