Flask-CouchDB : filtering per tag AND date

Hi,

I'm using Flask-CouchDB and I have an issue with displaying content per tag
and date.

Here is what I have :

class Bookmark(Document):
    title = TextField()
    description = TextField()
    author = TextField(default=DISPLAY_NAME)
    created_at = DateTimeField(default=datetime.datetime.now)
    tag = ListField(TextField())
    url = TextField()
    hash = TextField()
    doc_type = "Bookmark"
    type = TextField(default="bookmark")

    tagged = ViewField('bmarks', '''\
        function (doc) {
          if (doc.type == "bookmark" && doc.created_at && doc.tag != "") {
            doc.tag.forEach(function (tag) {
              emit([tag, doc.created_at], doc);
            });
          };
        }''', descending=True)

[...]

@app.route('/tag/<tag_name>')
def show_marks_for_tag(tag_name):
    page = paginate(Bookmark.tagged[tag_name], 10,
request.args.get('start'))
    return render_template('tag.html', page=page, tag_name=tag_name)

If in my view, I only have :

 emit(tag, doc);


It works but at a date point of view, it's a mess.

I would like to filter per tag and per date. Looks this one works in Futon
:

emit([tag, doc.created_at], doc);

Looks that page remains empty in this case.

So did I miss something or are there some bugs ?

Thanks,
Nicolas
