Rails SQL query in controller method - sql

Question

I want to retrieve brand name depending on brand_id which is mentioned in the another table products. My brand ids are stored as an array in 'brandids'. Here is my controller code.
def index
catids = Array.new
brandids = Array.new
#products = nil
if(!(params[:catid].nil?) && params[:catid].to_s.downcase != "all")
catids = arrayConvertion(params[:catid])
end
if(!(params[:brandid].nil?) && params[:brandid].to_s.downcase != "all")
brandids = arrayConvertion(params[:brandid])
end
if(catids.length == 0 && brandids.length == 0)
#products = Product.solr_search do
paginate :page => params[:page], :per_page => 3
end
#brands={}
#products.each do |p|
brand = p.BrandsTest.first(p.brands_test_id)
#brands[p.id] = BrandsTest.name
end
end
and the view for this controller is:
<% #products.results.each do |p| %>
<%= image_tag("Images/#{p.id}.jpeg",:alt => p.name) %>
<p> Name: </p>
<%= p.name %>
<p> Price: </p>
<%= p.price %>
<p> Discount: </p>
<%= p.discount %>
<p> Brand Name: </p>
<%= #brands[p.id] %>
<% end %>
Product Model code is:
class Product < ActiveRecord::Base
belongs_to :brands_test
belongs_to :categories_test
attr_accessible :id, :name
searchable do
integer :id
text :name
integer :brands_test_id
integer :categories_test_id
end
end
What query should I need to add and where I have to add?
Please help me with this.

Answer 1

#products = Product.solr_search do
with :brands_test_id, brandids[0..brandids.length]
paginate :page=>params[:page], :per_page=>3
end
#brands={}
#products.each do |p|
brand=Brand.find_by_id(p.brand_id)
#brands[p.id]=brand.name
end
views:
<% #products.results.each do |p| %>
#other code
<p> Brand: </p>
<%= #brands[p.id]
<% end %>
I don't sure if I understood what are you trying to do.

I did some modification according my app with the answer that you gave.Here is the controller part.
if(catids.length == 0 && brandids.length == 0)
#products = Product.solr_search do
paginate :page=>params[:page], :per_page=>3
end
#brands={}
#products.results.each do |p|
brand=BrandsTest.find_by_id(p.brands_test_id)
#brands[p.id]=brand.name
end
end
Here is view part:
<% #products.results.each do |p| %>
<%= image_tag("Images/#{p.id}.jpeg",:alt => p.name) %>
<p> Name: </p>
<%= p.name %>
<p> Price: </p>
<%= p.price %>
<p> Discount: </p>
<%= p.discount %>
<p> Brand Name: </p>
<%= #brands[p.id]%>
<% end %>
