Subject Re: Cryptic view errors popping up
Date Tue, 08 Apr 2008 22:07:58 GMT
Some additional info if that might help you:

The three views that are causing me trouble today look like this. It  
has worked perfectly

function(doc) {
	if (doc.class ==  "Feed"){
		map(doc.attributes.feed_id, doc);
	}
}

function(doc) {
	if (doc.class == "Feed" && doc.attributes.being_checked == false) {
		map(doc.attributes.next_check, doc);
	}
}

function(doc) {
	if (doc.class == "Feed" && doc.attributes.being_checked == true) {
		map(doc.attributes.next_check, doc);
	}
}

A typical document with class == "Feed" would look like this:

{
	"_id":"57FE8B5DDF5FA55537D76EEB7C4F7C62",
	"_rev":"346516073",
	"class":"Feed",
	"attributes":
	{
		"title":"The Unofficial Apple Weblog (TUAW)",
		"feed_url":"http:\/\/www.tuaw.com\/rss.xml",
		"url":"http:\/\/www.tuaw.com",
		"feed_id":"http:\/\/www.tuaw.com\/rss.xml",
		"description":"The Unofficial Apple Weblog (TUAW)",
		"last_updated":null,
		"copyright":"Copyright 2008 Weblogs, Inc. The contents of this feed  
are available for non-commercial use only.",
		"being_checked":false,
		"generator":"Blogsmith http:\/\/www.blogsmith.com\/",
		"image":"http:\/\/www.tuaw.com\/media\/feedlogo.gif",
		"next_check":1207692728,
		"was_scheduled_for_check":1207691521
	}
}


Best regards
Sebastian
