Sorry for the slightly noobish question, as I am writing my first rails app.

I get the idea of the layout view, but if you are using them, is there any way to includ

You can add a stylesheet tag inside the head tag of the layout by doing something like this:

layouts/products.html.erb:
```
    <head>
        ...
        <%= yield :css %>
        ...
    </head>
```
products/edit.html.erb
```
<% content_for :css do
    stylesheet_link_tag 'products_edit'
end %>
```

You can't if your </head> tag is in your layout.

You may want a different layout for that controller action. Like this on the render:
```
 render :action => "index", :layout => "some_other_layout
```
Also you can set a different default layout for a whole controller with this line in the controller class:
```
layout "some_other_layout"
```
Check the API docs, there's some complex things you can do with conditionals on that layout method.

If you have a generic edit.css file, I would suggest an if in your layout
```
<%= stylesheet_link_tag 'edit' if params[:action] == 'edit' %>
```
Otherwise you can use content_for with a yield to add additional tags into the head.

layout.html.erb
```
<head>
  ...
  <%= yield(:header) if @content_for_header %>
</head>
```
products/edit.html.erb
```
<% content_for :header do -%>
  <%= stylesheet_link_tag 'edit_product' %>
<% end -%>
```
