Description
|
|
-----------
|
|
Extracts a tuple of values from the request context and provides them to the inner route.
|
|
|
|
|
|
The ``textract`` directive is used as a building block for :ref:`Custom Directives` to extract data from the
|
|
``RequestContext`` and provide it to the inner route. To extract just one value use the :ref:`-extract-` directive. To
|
|
provide a constant value independent of the ``RequestContext`` use the :ref:`-tprovide-` directive instead.
|
|
|
|
See :ref:`ProvideDirectives` for an overview of similar directives.
|
|
|
|
See also :ref:`-extract-` for extracting a single value.
