Form_for vs. form_with in Rails 5 with namespace

I have a namespaced resource in my Rails 5 app and want the correct form for it.

My scaffold for Platform in Rails 5 gave me:

<%= form_with(model: platform, local: true ) do |form| %>

In Rails 4 I would include my namespace ('customer') like:

<%= form_for [:customer, @platform] do |f| %>

So what is the equivalent in Rails 5?

In your form you would do something like this. 

<%= form_for [@customer, @platform] do |form| %>
    ...
<% end %>

In new.html.erb or equivilent new method:

<%= render 'form', customer: @customer %>

In your new controller method (depending on your relationships) 

def new
  @customer = @platform.customers.build
end

Using form_with

<%= form_with(model: [:customer, @platform]) do |form| %>
  ...
<% end %>
