Can I convert model with one of its associations to YAML format?

Question

I want to print ActiveRecord model in YAML format for debugging purposes.

Currently I invoke model.to_yaml. But it doesn't return model's associations

How can I convert model with one of its associations to YAML format?

Answer 1

You can convert to json first. The default ActiveRecord as_json method allows you to include assocations. From there, it's straightforward to convert to yaml. Example:

menu.as_json(include: :dishes).to_yaml

Answer 2

to_yaml ignores the include-parameter ... but you could do the following:

Hash.from_xml(menu.to_xml include: :dishes).to_yaml
