Unique Rails Search Results

Question

I am using Ernie Miller Metasearch in rails 3 application and have encountered a problem.

In my model

class Prospect < ActiveRecord::Base has_many :steps 

In my controller

 @search=Prospect.search(params[:search]) 

In my opinion (search form)

  <%= f.date_select :steps_updated_at_greater_than%> 

This works so that I get all Outlook where the steps have been updated from select_date. My problem is that if there were a few updated steps, I get duplicates in @search that I don't need when I move on to formatting search results in the view.

My question is the best way to remove duplicates from @search? Or prevent duplication from adding to @search in the first place?

Answer 1

Do you want to:

 @search = Prospect.search(params[:search]) @search.relation.select("DISTINCT(step_id), prospects.*") 

Answer 2

 @search=Prospect.search(params[:search]).select('DISTINCT step_id') 

Answer 3

 @search = Prospect.search(params[:search]) @prospects = @search.relation.uniq
