| | | ``traverse`` argument provided to ``add_route`` is |
|---|
| | | ``/{article}``, when a request comes in that causes the route |
|---|
| | | to match in such a way that the ``article`` match value is |
|---|
| | | '1' (when the request URI is ``/articles/1/edit``), the |
|---|
| | | ``'1'`` (when the request URI is ``/articles/1/edit``), the |
|---|
| | | traversal path will be generated as ``/1``. This means that |
|---|
| | | the root object's ``__getitem__`` will be called with the |
|---|
| | | name ``1`` during the traversal phase. If the ``1`` object |
|---|
| | | name ``'1'`` during the traversal phase. If the ``'1'`` object |
|---|
| | | exists, it will become the :term:`context` of the request. |
