wicked

Wicked is a gem that makes creating a step-by-step wizard really simple.

I was using it on a project recently and wanted to show the user their progress through the wizard.

An easy way to do this would be to show “Step x of x”  on the page. Wicked doesn’t give you the step numbers, but they are easy enough to grab. Here’s how you do it.

In your show action, add the following.

@current_step = current_step_index + 1
@total_steps = steps.count

Your show action should now look something like this…

def show
  @user = current_user
  @current_step = current_step_index + 1
  @total_steps = steps.count
  render_wizard
end

Then in your view, you can now easily display your users progress through the wizard.

<%= Step #{@current_step} of #{@total_steps} %>

Annnd you’re done! Your users will now see what step they are on as they use your wizard.
