Instance Method Details

#render(object, template, options = {}) ⇒ Object

Renders object with the given rabl template.

Object can also be passed as an option : { locals: { object: obj_to_render } }

Default render format is JSON, but can be changed via an option: { format: ‘xml’ }

If template includes uses of instance variables (usually defined in the controller), you can passed them as locals options. For example, if you have this template:

object :@user
node(:read) { |u| u.has_read?(@post) }

Your method call should look like this:

RablRails.render(user, 'users/show', locals: { post: Post.new })
