Scoping the results for rails3 jquery autocomplete plugin

Question

I\'m using https://github.com/crowdint/rails3-jquery-autocomplete and it seems to be working. The only problem is lets say I have a field performing an autocomplete on all p

Answer 1

Even though I havent personally tested, I think normal scope method in rails3 should work. As after all scope is also a method same as "funky_method"

write a scope

in your model

scope :funky_method, lambda { |param1| :conditions => {:column = param1} }

and in your controller

autocomplete :brand, :name, :display_value => :funky_method

should work, try and see..

You should overwrite the method get_item, for example in these case I'm filtering the list of users to consider to just the last one:

class UsersController < ApplicationController
    autocomplete :user, :email, :full => true

    def index
        @users = User.all
    end

    def get_items(parameters)
        [User.last]
    end

I think that one of the last commits, changed the method (#get_items) name. Check you version of autocomplete.rb file.

Check it here: https://github.com/crowdint/rails3-jquery-autocomplete/commit/b3c18ac92ced2932ac6e9d17237343b512d2144d#L1R84.

Answer 3

You can override get_autocomplete_items, but first use super to call the original get_autocomplete_items method, and then filter the results by current_user.id (or post.user.id if the owner of the post is not the current user)

 def get_autocomplete_items(parameters)
    items = super(parameters)
    items = items.where(:user_id => current_user.id)
  end

This way you can still all the other options that come with the gem. This should be done in your controller by the way.

Another answer suggested the :scope option. I looked into that, but it is not the way to go in this case, you don't want to add "current_user" and things like that to your models.
