Ruby on Rails SOLR facets between 2 models - ruby-on-rails

Question

In my classifieds app , my "main" model is Classifieds but i have also implemented categorization so Categories has_many :classifieds
Also i have implemented my Categories with awesome_nested_set
And i have Solr search too!
In my sites Classifieds - index.html.erb i render the Classifieds and if search is used i render the corresponding Classifieds.
Now i have implemented a navbar which uses the Category model for navigation.
The navbar shows the Category.roots and the descendants of each root with a dropdown. This leads to the Category - show.html.erb ,where Classifieds are shown according to the Category they are in!
So the question is here:
In my Classifieds - index.html.erb i have successfully implemented Solr facets , which are used as filters but this only works when the user either Searches or just filters in the initial index! So in simple words when he interacts with the Classifieds Controller.
How can i preserve the facet functionality when the user uses the navbar , which means he then interacts with the Category controller
Models:
class Classified < ApplicationRecord
belongs_to :user
belongs_to :category
has_many :photos, dependent: :destroy, inverse_of: :classified
has_many :favorite_classifieds, dependent: :destroy
has_many :favorited_by , through: :favorite_classifieds , source: :user #for the favorite_by to work :source is needed
accepts_nested_attributes_for :photos
searchable do
text :title, :boost => 5
text :model , :created_month , :make , :make_country , :condition ,:treecat,:cat,:price #TO BE CHANGED TO CURRENCY FORMAT
time :created_at
string :treecat
string :price #TO BE CHANGED TO CURRENCY FORMAT
string :created_month
string :cat
string :make_country
string :condition
string :make
string :model
end
def cat
category.root.name
end
def treecat
category.name unless category.name == category.root.name
end
def created_month
created_at.strftime("%B")
end
end
class Category < ApplicationRecord
acts_as_nested_set
has_many :classifieds
end
Classifieds controller index action
def index
#search = Classified.search do
paginate(:page => params[:page] || 1, :per_page => 10)
order_by(:created_at , :desc)
fulltext params[:search]
with(:created_at)
active_model = with(:model ,params[:model]) if params[:model].present?
active_make = with(:make , params[:make]) if params[:make].present?
active_make_country = with(:make_country , params[:make_country]) if params[:make_country].present?
active_condition = with(:condition,params[:condition]) if params[:condition].present?
active_category = with(:cat,params[:cat]) if params[:cat].present?
active_subcategory = with(:treecat,params[:treecat]) if params[:treecat].present?
facet(:model)
facet(:make)
facet(:make_country)
facet(:condition)
facet(:cat , exclude: active_subcategory)
facet(:treecat)
end
#classifieds = #search.results
end
Categories controller show action
def show
#category = Category.find_by_id(params[:id])

im a noob , i know there's stuff wrong with my indentation in html , sorry for that!

Answer 1

Ok i did it by nesting routes and taking some fields from the categories model.
resources :categories do
resources :classifieds do
end
end
Category model:
def nested_classifieds
Classified.where(category_id: self_and_descendants.select(:id))
end
def nested_categories
self_and_descendants
end
Classifieds controller
def index
if #category.present?
#classifieds = #category.nested_classifieds
nested_categories = []
#category.nested_categories.each do |f|
nested_categories << f.id
end
#search = Sunspot.search(Classified ) do
paginate(:page => params[:page] || 1, :per_page => 10)
order_by(:created_at , :desc)
fulltext params[:search]
with(:categoryid,nested_categories)
active_model = with(:model ,params[:model]) if params[:model].present?
active_make = with(:make , params[:make]) if params[:make].present?
active_make_country = with(:make_country , params[:make_country]) if params[:make_country].present?
active_condition = with(:condition,params[:condition]) if params[:condition].present?
active_category = with(:cat,params[:cat]) if params[:cat].present?
active_subcategory = with(:treecat,params[:treecat]) if params[:treecat].present?
active_pricerange = with(:price, params[:price]) if params[:price].present?
fulltext params[:prc]
facet :price
with(:price).less_than(1000)
facet(:model)
#facet(:model , exclude: active_condition)
facet(:make)
facet(:make_country)
facet(:condition)
facet(:cat)
facet(:treecat)
end
#classifieds = #search.results
else
#redirect_to '/'
##classified=#search.results
search
end
end
