When I point my browser to the app url, it works perfectly, but when I try to include the view in my project it displays the base panel with an error, and the dictionary I passed to the view does not appear to be available.

问题 How can I print out the name of current layout in a view? Example puts controller.current_layout Thx 回答1: This works with Rails 3.0.7: controller.send :_layout Obviously, it's a private method, so use at your own risk. 回答2: This works for me: response.layout UPDATE: True, response.layout does not work in rails3+ thus I usually define a @layout_name variable inside each layout. Example of application.html.haml - @layout_name = 'application' !!! Strict %html ... 回答3: <%= controller.active

The way I thought that I could do this was by getting the ListView from the ListActivity and then getting the view that I wanted to change

问题 In MS Access 2007, I want to switch between datasheet and form views, without filtering, and remain on the current record. Should I use a bookmark ? How ? or How might I place a button on the ribbon to switch views, without having to search for the record or use a filter.
