Re: Using underscorejs in a couchapp list

[AL]

Thanks Jim and Ryan,

kanso seems quite interesting indeed :)
I have started a small project based on it, but unfortunately I haven't 
been able to solve my problem.

I was wondering if the folks on the list could have a look at it? I 
really can't spot the problem...

The project is available here:

https://github.com/aleray/lgru.couch

Visiting the following URL will log variable `_`, which is undefined in 
my case...

http://127.0.0.1:5984/mydb/_design/lgru/_list/publications/publications

Thanks a lot,

Alex

Alex,

If you are making a couchapp, and you want to use underscore, you
should give http://kan.so/ a try. There is a kanso package already for
underscore:

http://kan.so/packages/details/underscore

Kanso makes using commonjs modules very easy, and there are lots of
packages already available.

Hi all,

I'm running archlinux and couchdb 1.2. I'm trying to develop a couchapp:
although I could use couchdb only as a database, I like the idea of
"self-containess" in couchapps. The application I want to build is fairly
simple, consisting of list and detail views. I have a set of books described
in a bibtex-like fashion, and I'm trying to serve a webpage that lists the
whole collection, organized by year. Here is my view map:

    function(doc) {
      if (doc.application === "publication") {
        emit([doc.year, doc.title], doc);
      };
    }

I'd like to get a webpage consisting of several ul tags; one for every year.
The getrow() function makes it easy to make one big list (1. opening the
list, 2. creating a list element for every row, 3. closing the list) but for
what I want to achieve it seems a little bit trickier.

My idea was to use underscorejs `_.sortBy` method to reorganize the data by
year into a dictionary, to end up with something like this:

    {
      '2009': [
        {'title': ' The Transformer -- Principles of Making Isotype Charts',
...},
        {'title': ' Verbindingen/Jonctions 10, Tracks in Electr(on)ic
Fields', ...},
        {...}
      ],
      '2012': [
        {'title': 'Tying the Story to Data: The graffiti Markup Field
Recorder Challenged, GML', ...},
        {'title': 'Inside Photoshop', ...},
        {...}
      ],
      ...
    }

 From there, I'd be able to loop through each key and append to my html
output an HTML list. Unfortunately, I'm unable to import underscorejs, as it
seems like they have dropped support for commonjs. There are forks and
similar libraries that are supposed to work, but whatever I try, it fails
(see my question here:
http://stackoverflow.com/questions/11781502/using-underscorejs-in-a-couchapp-list/11817375#11817375).

So I'd like to know whether it is achievable in this way or another, and if
my direction is correct, how I can use underscorejs (or similar) in a
couchapp.

Thanks a lot,

Alex
