Using Rails 4.2

I have two models, `suppliers` and `clients`. Both models contain a `name` (string) and `email` (string). They do not have any relationship between them. 

I would like to generate a list of all the names and emails from both suppliers and clients. In this list I would also like to know if the partner is a supplier or client.

**Controller**

```
@suppliers = Supplier.all
@clients = Client.all

@all_partners = (@suppliers + @clients).sort { |x, y| x.name <=> y.name }

```

**View**

```
<% @all_partners.each do |partner| %>
  <%= partner.name %>, <%= partner.email %>, <%= partner.type %>
  <!-- I need some way to know if the partner type is a supplier or client -->
<% end %>

```

How can I put in which type of partner it is? Is there a way to do this with one single AR call or query? This is basically how to use an SQL Union statement in Rails.
