This will not be a problem as long as the variables are defined before the extend directive. This behavior can be used to extend a layout in more than one place a standard layout is extended at the point where the include directive occurs . The idea is to define view functions that generate separate portions of the page for example sidebar 146 THE VIEWS 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 1 1 2 1 2 3 4 5 6 7 maincontent and render them in different parts of the layout. The view functions are called in the layout at the points we want them rendered. For example in the following layout html body include -- must come before the two blocks below -- whatever html maincontent whatever html if sidebar in globals sidebar whatever html .
