<p>How do I "name" a browser window in ROR, such that I can open a page in it later, from another (popup) window (using the target="name" html parameter)</p>

You have to use JavaScript for this:
```
```
<script type="text/javascript">
  window.name = "MyWindow";
</script>
```
```
Of course you could easily package this up into a Rails helper method. For example, in
```
app/helpers/application_helper.rb
```
add a new method:
```
```
def window_name(name)
  content_for(:window_name) do
    "<script type=\"text/javascript\">window.name = \"#{name}\";</script>"
  end
end
```
```
Next, in your layout file, add this line somewhere within the HTML
```
<head>
```
element:
```
```
<%= yield :window_name %>
```
```
Finally, in your view templates, simply add a line like this (can be anywhere you want) to output the correct JavaScript:
```
```
<% window_name 'MyWindow' %>
```
```
