ruby on rails实现了通用搜索

Question

I have 2 tables in my DB - an "illness" table and a "symptoms" table. I've implemented a generic search for searching both tables. My goal is to display the results in the result page, each result should be a hyperlink that leads to the result "show" page (illness/id/show or symptom/id/show).

As i'm passing generic results to the result page, I don't really know whether the current result is an illness or a symptom. I wonder what is the best way to get this information (Should I try to collect this informaiton in the controller and somehow pass it to the html? should I somehow run another query from the html?)

I'm using rails 3.x, and my controller code looks like this:

class SearchController < ApplicationController
    def index
        @results = Illness.search(params[:search]) + Symptom.search(params[:search])

        respond_to do |format|
            format.html # index.html.erb
            format.json { render json: @results }
        end
    end
end

Thanks, Li

You don't have to be worried about it. Let the Rails to serve it:

   - @results.each do |result|
     = link_to 'Show', result

And you'll get the proper link based on the result's type.

And one more. What the show in URL has to do with the show action in your examples like: symptom/id/show ? The show action is mapped by default to GET /model/id path.
