subscription docs?

[bowlofudon]

The subscription param isn't well documented. Would be easier to implement if it was clearer.

[mizzao]

What confuses you about it?

[bowlofudon]

Trying to figure out how to implement the following using what was provided: "Use of a custom publish function also allows you to use full-text search services outside of Meteor, such as ElasticSearch."

Would be super awesome to get an example here.

[mizzao]

I think @queso recently provided an example in #36; I agree the documentation could be improved.

Can you take a look at what he did and suggest how we might write documentation for that? I thought that the publish function in the server code would be enough of an example.

[bowlofudon]

For example, it'd be nice if there was an example showing how ElasticSearch would work.

[mizzao]

I've never used it. It's just that some user suggested it, and we figured an advanced enough developer would be able to figure out how to send a query to the ElasticSearch cloud and push the results back out into a publication.

[dandv]

One problem with ElasticSearch (or the new $text operator in Mongo 2.6) is that searches can't be replicated on the client with the same server selector. This might present problems with more than one server-side collection (#41).

[mizzao]

I don't think #41 is a real problem - https://github.com/mizzao/meteor-autocomplete/issues/41#issuecomment-42396252.

[bowlofudon]

I mean, I think it would be great if there was any example - elastic search or not - of how this would function. I've managed to make this work with Facebook api data, but it would of been a lot easier if there was an example. You could even demonstrate this using flickr image search for example.

[mizzao]

@bowlofudon - I'd love it if you would make one and add it to our examples directory!

[mizzao]

If you could create an autocomplete box that uses the Flickr image search API and displays image thumbnails in templates, that would be super awesome.

[mizzao]

Note to self - add a helper for publishing cursors on the server.

[mizzao]

For anyone who is still interested in this, if you check out the new file at

https://github.com/mizzao/meteor-autocomplete/blob/master/autocomplete-server.coffee

You'll see that it's a lot easier to write a publication when you have an existing cursor, using the convenience method.

[queso]

Wow :+1: :+1:

[mizzao]

Not that much wow, right? Just used a function that already exists.

[dcworldwide]

I'm really new to meteor and coffee script, as such i don't really understand how to use the Autocomplete.publishCursor interface. I'm attempting to create a service side subscription that exposes all Meteor Users to the AutoComplete client.

With my limited understanding, i've tried:

Server:

    Autocomplete.publishCursor(function() {
        return Meteor.users.find();
    },this);

Client:

AutoCompleteRecords = new Mongo.Collection("autoCompleteRecords")

Template.testTemplate.helpers({
     addMemberAutoCompleteSettings: function() {
            return {
                position: "top",
                limit: 5,
                rules: [
                    {
                        token: '@',
                        collection: 'autoCompleteRecords',
                        field: "username",
                        template: Template.addTemplate
                    } ]
            };
        }

Could you please point me in the right direction? Thanks

[mizzao]

Try this:

Server (add appropriate security features as in the example):

Meteor.publish("autocompleteUsers", function(selector, options) {
  Autocomplete.publishCursor(Meteor.users.find(selector, options), this);
  this.ready();
});

Client:

Template.testTemplate.helpers({
     addMemberAutoCompleteSettings: function() {
            return {
                position: "top",
                limit: 5,
                rules: [
                    {
                        token: '@',
                        subscription: 'autocompleteUsers',
                        field: "username",
                        template: Template.addTemplate
                    } ]
            };
        }
});

[dcworldwide]

Thanks. It works :+1: But i had to add collection: 'autocompleteRecords', to my settings.

[mizzao]

Ah, that was a bug. That string is completely meaningless, as the collection is determined by what you do in the subscription. You won't need to do this in the next release.

[jota3]

Hi, I've tried to make the autocomplete work from a subscription as you mentioned (see below) but I get an error from the validateRule method : 'ReferenceError: Can't find variable: Match'. Can you tell me what I am missing ? Thanks !

//Server
Meteor.publish('autocomplete-test', function(selector, options) {
     Autocomplete.publishCursor(Categories.find(selector, options), this);
     return this.ready();
});

//Client
autoCompleteSettings: function() {
    return {
      position: "bottom",
      limit: 10,
      rules: [
        {
          token: '@',
          subscription: "autocomplete-test",
          field: "name",
          template: Template.searchPill
        }
      ]
    };
  }

Edit : I was missing the check module from meteor. If you get the same error just do a meteor add check

Hello,

I've tried the code above but I keep getting this error:

Exception from sub autocomplete-recordset id vRAdRMiPfmbGdCmov Error: autocompleteViewers is not defined on the global namespace of the server

Here's my server code: Meteor.publish("autocompleteViewers", function(selector, options) { Autocomplete.publishCursor(viewers.find(selector, options), this); this.ready(); });

And the client: getSettings: function() { return { position: 'bottom', limit: 5, rules: [{ collection: 'autocompleteViewers', field: '_id', matchAll: false, options: '', template: Template.dLegend }], }; },

Am I missing something? Any pointers would be greatly appreciated.

[mizzao]

Try subscription: "autocompleteViewers"

Thanks. I don't get an error on the server anymore but the client triggers an exception: Error: Collection name must be specified as string for server-side search at validateRule

[epileptic]

Is there a minimum working example featuring server-side autocompletion using a custom publish function somewhere? I could go from there and try to figure out what's wrong. The examples provided in the package only work with the insecure package which isn't really a typical scenario.

[epileptic]

When I inspect the code that's triggering the exception, this is what I see:

validateRule = function(rule) {
  if ((rule.subscription != null) && !Match.test(rule.collection, String)) {
    throw new Error(Collection name must be specified as string for server-side search);
  }
};

And in the package source, validateRule starts out like this:

validateRule = (rule) ->
  ...
  unless rule.subscription? or Match.test(rule.collection, Match.OneOf(String, Mongo.Collection))
    throw new Error("Collection to search must be either a Mongo collection or server-side name")

This doesn't look right to me.

[mizzao]

Oh, I meant remove collection: ... entirely and just use subscription: ...

[epileptic]

I did. I just replaced collection by subscription.

[aessig]

Any updates ?
