Rails & Sunspot facets and filtering - ruby-on-rails

Question

Pretty much a noobie here, so I appreciate any help someone can give.
I'm trying to add faceting to the search on my site through Sunspot. Ryan just released a great Railscast which got me started: http://railscasts.com/episodes/278-search-with-sunspot. I got that working and was able to add additional facets. My problem is that the facets are independent of each other. If I have 3 facets on 3 different attributes, when I select a facet once I already have on selected, I would like to display only results falling into both of those facests. As of now, it just switches from one facet to the other. I feel like this shouldn't be that difficult, but I can't figure out how to do it.
I did find this tutorial: http://blog.upubly.com/2011/01/06/using-sunspot-in-your-views/ which I think is doing what I want. I tried to get this working but, even when I attempt to make it work with just one facet I don't any results listed. Just the facet name and then nothing else.
Thoughts?
Thank you!!
UPDATE
Here is the code samples of what I am trying to do:
Adjusting the Railscasts code I got this:
In my StylesController:
def index
#search = Style.search do
fulltext params[:search]
facet :departmental, :seasonal, :classifier
with(:departmental, params[:department]) if params[:department].present?
with(:classifier, params[:classification]) if params[:classification].present?
with(:seasonal, params[:season]) if params[:season].present?
end
In my Style Index view (I know I need to condense this)
= form_tag styles_path, :method => :get do
%p
= text_field_tag :search, params[:search]
= submit_tag "Search", :name => nil
#facets
%h4 Departments
%ul
- for row in #search.facet(:departmental).rows
%li
- if params[:department].blank?
= link_to row.value, :department => row.value
(#{row.count})
- else
%strong= row.value
(#{link_to "remove", :department => nil})
%h4 Classifications
%ul
- for row in #search.facet(:classifier).rows
%li
- if params[:classification].blank?
= link_to row.value, :classification => row.value
(#{row.count})
- else
%strong= row.value
(#{link_to "remove", :classification => nil})
%h4 Seasons
%ul
- for row in #search.facet(:seasonal).rows
%li
- if params[:season].blank?
= link_to row.value, :season => row.value
(#{row.count})
- else
%strong= row.value
(#{link_to "remove", :season => nil})
In my Style Model:
searchable do
text :number, :description, :department, :classification, :season
string :departmental
string :classifier
string :seasonal
end
def departmental
self.department
end
def classifier
self.classification
end
def seasonal
self.season
end
And my version of the upubly code, paired down to just try to get the "seasonal" facet working:
I left the the Search Partial, the Search Model and the SearchHelper the same as in the example. I tried to mess with the Helper as my Facets will be pulling text values, not just IDs of other Models, but to no avail. I don't have my various attributes set up as individual Models as I didn't think I needed that functionality, but I am starting to think otherwise.
StylesController:
def index
#title = "All styles"
#search = search = Search.new(params[:search]) # need to set local variable to pass into search method
#search.url = styles_path
#search.facets = [:seasonal]
#solr_search = Style.search do
keywords search.query
with(:seasonal, true)
search.facets.each do |item|
facet(item)
with(:seasonal, params[:season]) if params[:season].present?
end
any_of do
# filter by facets
search.facets.each do |item|
with(item).all_of( params[item].try(:split, "-") ) if params[item].present?
end
end
paginate(:page => params[:page], :per_page => 10)
end
Again, I appreciate the help. Definitely a noob, but really enjoying the process of building this site. Stackoverflow has been a HUGE help for me already, so I owe everybody who posts answers on here a big-time thank you.

Answer 1

I needed the answer to this myself, and seeing as there seems to be nothing else on the web about it, I decided I'd try to figure it out myself.
First I came to the conclusion through logic, that the controller can handle multiple facets and there's no reasons it cannot, I remembered that the best part about ruby is that it is the most human readable code, try to read your first controller and you'll see that it makes sense that it works. I tested this by manually entering in a query string in url, which returned expected results. Therefore, once I figured that out, I knew the issue resided in my view (which made me facepalm because it's fairly obvious now)
Your example is significantly more complex than mine, and my answer might not 100% meet every requirement but I'm pretty sure it's close. Also your code in your model regarding "departmental" etc is a little redundant in my view
Controller
def index
#search = Style.search do
fulltext params[:search]
facet :departmental, :seasonal, :classifier
with(:departmental, params[:department]) if params[:department].present?
with(:classifier, params[:classification]) if params[:classification].present?
with(:seasonal, params[:season]) if params[:season].present?
end
View
%h4 Departments
%ul
- for row in #search.facet(:departmental).rows
%li
- if params[:department].blank?
= link_to row.value, styles_path(
:department => row.value,
:classification => (params[:classification] unless params[:season].blank?),
:season => (params[:season] unless params[:season].blank?))
(#{row.count})
- else
%strong= row.value
= link_to "remove", styles_path(
:department => nil,
:classification => (params[:classification] unless params[:season].blank?),
:season => (params[:season] unless params[:season].blank?))
