Question

I have a MongoDB collection with data that was not saved through my Derby app. I want to query against that and pull it into my Derby app.

So, I figured that out and here’s the code to do it:

get '/:year', (page, model, params) ->
  query = model.query 'years', 
    where:
      year: (parseInt params.year, 10)
    limit: 1
  model.subscribe query, (err, year) ->
    if err
      console.log err

    page.render
      y: year.get(),
      year: params.year

The only problem is that the documents don’t have a derby id, so it sets the MongoDB objectid (_id) to the derby id. Here’s an example of the JSON that the model.get() returns: https://gist.github.com/0a5426d2b28a940e8803

I have no way of knowing what the objectid is before the query. I would love if the most recently returned id (currID) was in the object’s top level so I could just query that and set a model reference. I built a hack to get around it for now, but it’s not as smooth as I wish it would be. The code is below:

getId = (obj, year) ->
  for x of obj
    return obj[x].id if obj[x].year is year
  -1

Also, is there any way to update templates without destroying some templates already on the screen? Instead of doing a full page.render just doing a template.render?

Thanks

Racer queries were just updated in 0.3.11, and are described in this readme file: https://github.com/codeparty/racer/blob/master/lib/descriptor/query/README.md
