# In controllers, use `render dt: model` rather than `render json: model, adapter: :dt`.
#
# For example, in a controller action, we can:
# respond_to do |format|
# format.dt { render dt: model }
# end
#
# or
#
# render dt: model
#
# No wrapper format needed as it does not apply (i.e. no `wrap_parameters format: [dt]`)
