jinja2.contextfunction¶

jinja2.contextfunction(f)[source]¶

This decorator can be used to mark a function or method context callable. A context callable is passed the active Context as first argument when called from the template. This is useful if a function wants to get access to the context or functions provided on the context object. For example a function that returns a sorted list of template variables the current template exports could look like this:

@contextfunction
def get_exported_names(context):
    return sorted(context.exported_vars)
