Wicked gem Rails - How to create a new object

问题

The Building Partial Objects Step by Step page on the Wicked Gem Wiki explains how to create an object step by step with wicked.

But how do I have to create a new Product object?

Do i have to do that in the new action in the ProductsController ? And where do i have to redirect to ?

回答1:

The following statement is given in the Building Partial Objects Step by Step page.

This also means to get to the create action we don't have a product_id yet so we can either create this object in another controller and redirect to the wizard, or we can use a route with a placeholder product_id such as [POST] /products/building/build in order to hit this create action.

You can create the object in another controller and redirect to wizard or use a route with a placeholder to hit the create action.

Here is a sample from my app which worked for me

class RegistrationsController < Devise::RegistrationsController
  protected

  def after_sign_up_path_for(resource)
    user_background = resource.build_user_background
    user_background.save
    user_background_build_path(user_background.id, :first_step_name)
  end

end

This creates the UserBackground object and then passes the user to the first step of the wicked controller with the newly created object id.
