I have a controller that creates a grid off of a table -- very basic grid.
I test to see if the user is "viewing" an item in the grid (if request.args
and request.args[0] == 'view') and if so, I customize the view to present
the information in the grid in a different layout.
Now, I'd like to add a back button similar to what you get on the standard
view for a grid but without displaying the grid on the 'view' page.
I know how to create the button in the view, but I'm not sure how to create
the URL since it's using the signature in the link.
{{=A(T('Back'), _href=URL(????), _class='btn')}}
