[Rails] params in nested resources

Hi,

Already 2 ful days of trial and error...grgr. Can someone help me...

part of my tag model:

class Tag < ActiveRecord::Base
has_many :taggings
has_many :houses, through: :taggings
end
part of my house model

class House < ActiveRecord::Base
has_many :taggings
has_many :tags, through: :taggings

def self.tagged_with(name)
Tag.find_by_name!(name).houses
end

def self.tag_counts
Tag.select("tags.*, count(taggings.tag_id) as count").
joins(:taggings).group("taggings.tag_id")
end

def tag_list
tags.map(&:name).join(", ")
end

def tag_list=(names)
self.tags = names.split(",").map do |n|
Tag.where(name: n.strip).first_or_create!
end
end
end
part of my house controller:

def index
@country = Country.find(params[:country_id])
@regions = @country.regions

if params[:tag]
@houses = House.tagged_with(params[:tag])
else
@houses = Find(:all)
end
house index view:

.span9
#container
- @houses.each do |house|
.item{:class => house.features_to_html_class }
%article.chat.t_xs
.article-base
%section
.span4
%h2 #{link_to house.name, house_path(house)}
%p
When i visit house/tag/tagname

i get the correct houses who are tagged with current tagname. So this
works fine.

But because i implemented a new nested resources setup
(locale/country/region/houses) instead (/locale/houses) my view houses
index changed in this:

#container
- @regions.each do |region|
- region.houses.find_all do |house|
.item{:class => house.features_to_html_class }
%article.chat.t_xs
.article-base
%section
.row
.span4
%h2 #{link_to house.name,
country_region_house_path(@country, region, house)}
%p
But how i implement the tag feature in the new nested resources setup. I
thought changing the "find_all" method in this:

- @regions.each do |region|
- region.houses.tagged_with(params[:tag]) do |house|
This is not working...can someone advice/help me.

Thanks..remco
