Not able to get the rendered result in Rails console

[atopdev]

I am trying to get the rendered result in Rails console.

Rabl.render(@post, 'api/v1/posts/show', view_path: 'app/views', format: :xml)

But it fails due to this issue:
NameError (undefined local variable or method `request' for #Rabl::Engine:0x000...)

I can't figure out what this means.

Please help me to fix it so that I can get the result.
