Hey,
when you want to use an erlang view in the CouchDb, then you should parse the
code into one line only.
Here is my JSON for the design document and it works as expected on my server
without throwing an error:
{
"_id": "_design/erl_views9",
"_rev": "1-2eef401024e95ff6798c7a85cf614b58",
"language": "erlang",
"views": {
"getTemplates": {
"map": "fun({Doc}) -> Id = couch_util:get_value(<<\"_id\">>, Doc),
Doc_type = couch_util:get_value(<<\"TEMPLATE\">>, Doc),Emit(Id, Doc_type) end."
}
}
}
Best regards,
Michael
