necessary nor advisable to replace an entire template. It is almost always
better to override only the section of the template which you need to change.
To continue the example above, we want to add a new link next to the ``History``
tool for the ``Page`` model. After looking at ``change_form.html`` we determine
that we only need to override the ``object-tools`` block. Therefore here is our

directory, our link would appear on every model's change form.
