To use the helper methods already included in the template engine:
- Rails 2: use the
@template
variable. - Rails 3: has the nice controller method
view_context
Example usage of calling ‘number_to_currency’ in a controller method:
# rails 3 sample
def controller_action
@price = view_context.number_to_currency( 42.0 )
end
# rails 2 sample
def controller_action
@price = @template.number_to_currency( 42.0 )
end
