This is how the  root actor  mechanism works. \n             Authentication plugins can set signed  ds_actor  cookies themselves like so: \n             response = Response.redirect(\"/\")\nresponse.set_cookie(\n    \"ds_actor\",\n    datasette.sign({\"a\": {\"id\": \"cleopaws\"}}, \"actor\"),\n) \n             Note that you need to pass  \"actor\"  as the namespace to  .sign(value, namespace=\"default\") . \n             The shape of data encoded in the cookie is as follows: \n             {\n    \"a\": {... actor ...}\n}", "breadcrumbs": "[\"Authentication and permissions\"]", "references": "[]"}
