Question

Recently I started using https://github.com/crowdint/rails3-jquery-autocomplete

It works great, but I was trying to set a scope for the results that I was autocompleteing, in this question I got a good answer: Scoping the results for rails3 jquery autocomplete plugin

Using Claudio’s code I’ve successfully scoped as such:

class PostsController < ApplicationController
    autocomplete :post, :title

    def get_items(parameters)
        Post.where(:user_id => current_user.id)
    end

This works because I’m overwriting the plugin’s get_items method. Which you can see here: https://github.com/crowdint/rails3-jquery-autocomplete/commit/b3c18ac92ced2932ac6e9d17237343b512d2144d#L1R84 (I have a version before this commit, so get_items still works for me).

The problem with my scope, is the autocomplete functionality no longer works. When the person starts typing, the list specified in get_items just pops up, rather than items being suggested from that list.

I’m assuming I’m doing something wrong with my overwriting method. Any ideas?

Best,
Elliot

Answer 1

You just made me realize that overriding get_items is not as flexible as it should be.

Your code is missing the use of parameters[:terms]

Something like this should make it work:

def get_items(parameters)
  Post.where(:user_id => current_user.id).where(['title LIKE ?', "#{parameters[:term]}%"]
end

This is totally unfriendly, I’ll try and work on something that makes more sense

Or, maybe a :scope option for the autocomplete declaration makes more sense?
