class ContextReference(Expr): (source)

View In Hierarchy

Returns the current template context. It can be used like a :class:`Name` node, with a ``'load'`` ctx and will return the current :class:`~jinja2.runtime.Context` object. Here an example that assigns the current template name to a variable named `foo`:: Assign(Name('foo', ctx='store'), Getattr(ContextReference(), 'name')) This is basically equivalent to using the :func:`~jinja2.pass_context` decorator when using the high-level API, which causes a reference to the context to be passed as the first argument to a function.

Inherited from Expr:

Method as_const Return the value of the expression as constant or raise :exc:`Impossible` if this was not possible.
Method can_assign Check if it's possible to assign something to this node.

Method dump Undocumented
Method find Find the first node of a given type. If no such node exists the return value is `None`.
Method find_all Find all the nodes of a given type. If the type is a tuple, the check is performed for any of the tuple items.
Method iter_child_nodes Iterates over all direct child nodes of the node. This iterates over all fields and yields the values of they are nodes. If the value of a field is a list all the nodes in that list are returned.
Method iter_fields This method iterates over all fields that are defined and yields ``(key, value)`` tuples. Per default all fields are returned, but it's possible to limit that to some fields by providing the `only` parameter or to exclude some using the `exclude` parameter...
Method set_ctx Reset the context of a node and all child nodes. Per default the parser will all generate nodes that have a 'load' context as it's the most common one. This method is used in the parser to set assignment targets and other nodes to a store context.
Method set_environment Set the environment for all nodes.
Method set_lineno Set the line numbers of the node and children.
