It looks like you have not created a view for this function, so the 
generic.html view is being used instead. When you return multiple 
variables, the generic view displays the name of each variable. Since you 
are returning locals(), I assume you must have defined other variables in 
the index() function in addition to grid -- if grid were the only variable 
defined, the generic view would not show the "grid:" label.

As an alternative, you can either create a custom view (recommended), or 
just return the grid variable (i.e., return dict(grid=grid)).
