Inserting parent record's details into new page

I have a list of steps.

My step controller has the following method:

def display_stepinfo
@step = Step.find(params[:id])
@metrics = @step.step_metrics
end

Upon clicking a step, its metrics are displayed on a new page. On this
page I would also like to display a step field (step.name) of the step
that was previously selected.

Can anyone help me figuring out how to insert such a field?
