ruby - Render a jBuilder partial inside a Rails model -

i'm trying overwrite default to_json method in model. there numerous jbuilder partials models, named model does, in snake case. so:

jbuilder.encode |json|   json.partial! "charts/#{self.class.name.demodulize.underscore}" end 

but actually, got node in json, named "partial!" , string value.

how render jbuilder partial inside rails model?

as disclaimer, dirty hack. it's better avoid such code.

  builder = jbuildertemplate.new(applicationcontroller.new.view_context)   builder.partial!("foo/bar")   activesupport::json.decode(builder.target!)
