How to get it working with Keystone.js?

[art1c0]

First of all thanks for a great plugin! I'm trying to use your plugin within Keystone.js application and cannot get it working. Keystone uses own mechanism of Lists although it's based on mongoose. I tried to do something like that:

var list = keystone.list('Thing'); list.schema.plugin(deepPopulate); list.deepPopulate ---- method is undefined list.model.deepPopulate ---- method is undefined

If you can give any help on how to get this working it would be really great and will expand usage of your plugin as well :)

May be relating to this. Are you sure you didn't call list.register() before invoking list.schema.plugin()?

[art1c0]

Yes, that helped. Actually sequence should be the following:

var Thing = new keystone.List('Thing');
Thing.schema.plugin(deepPopulate);
Thing.register();

It works, but it has to be enabled for every model separately, it would be much better if that would be possible on all-models level...

Another question I met is how to select specific fields I want to get in the output? Now I get all models fully populated, which is not what I really want - I need only some properties for each model. How to define this?

The Mongoose way is mongoose.plugin(deepPopulate), should work with anything that uses Mongoose. If not, you should check with the Keystone.js guys.

select specific fields I want to get in the output

That's not supported now. This is something that can be implemented, but I need to think of a way to not make the API overly complicated.

Populate options (including custom select) is supported in v0.0.4.

And is it correct that querying should look like: Day.model.find().deepPopulate('userdays userdays.user').exec(function.... ?

Doing this throws an error " TypeError: Object # has no method 'deepPopulate' " Am I missing something?

[buunguyen]

Is this for Keystone.js? The gist is that this plugin extends the following Mongoose objects: query, model and model instance. I'm not sure how Keystone.js integrates with Mongoose, just make sure you invoke deepPopulate on the right object.

@articobandurini just so you know, the latest version of the plugin supports selecting specific fields for the output.

+1 I am also curious to know if anyones got this to work with Keystone.js?

I'm doing:

Post.paginate({
    page: req.query.page || 1,
    perPage: 50,
    maxPages: 10
}).populate('comments','author content date')
.deepPopulate('author.name')

and i included the plugin like so:

var deepPopulate = require('mongoose-deep-populate');
Post.schema.plugin(deepPopulate);
Post.register();

But i still get the error:

TypeError: undefined is not a function

Anyone got it working with keystone?

See https://github.com/buunguyen/mongoose-deep-populate/issues/18#issuecomment-110934841 (kudos to @AndrewFinlay). Basically Keystone and this plugin uses different instances of Mongoose. The fix is explicitly adding Mongoose as a dependency in package.json.
