-You can set global default parameters that will be used when generating URLs with +default_url_options+. To do this, define a method with that name in your controller:
+You can set global default parameters for URL generation by defining a method called +default_url_options+ in your controller. Such a method must return a hash with the desired defaults, whose keys must be symbols:
<ruby>
class ApplicationController < ActionController::Base
- # This method must return a hash with symbolized keys.
def default_url_options
{:locale => I18n.locale}
end
end
</ruby>
-These options will be used as a starting-point when generating URLs, so it's possible they'll be overridden by +url_for+. Because this method is defined in the controller, you can define it on +ApplicationController+ so it would be used for all URL generation, or you could define it on only one controller for all URLs generated there.
+These options will be used as a starting point when generating URLs, so it's possible they'll be overridden by the options passed in +url_for+ calls.

+If you define +default_url_options+ in +ApplicationController+, as in the example above, it would be used for all URL generation. The method can also be defined in one specific controller, in which case it only affects URLs generated there.
