Rails loop showing duplicate results - ruby-on-rails

Question

I have three models with the following associations:
class Product < ApplicationRecord
belongs_to :store
has_many :variants, dependent: :destroy
end
class Store < ApplicationRecord
has_many :variants
belongs_to :user
has_many :products, dependent: :destroy
end
class Variant < ApplicationRecord
belongs_to :product
belongs_to :store, optional: true
end
And I'm counting the products & variants of each user with the following:
#products = current_user.store.products.group(:subcategory_id).count
#variants = current_user.store.variants.group(:subcategory_id).count
The above returns this #products => {181=>1, 185=>1}
and this #variants => {181=>2, 185=>1}
Finally when I try to loop through each of the above hashes the results show up correctly but they also show up two times(dublicate results). Any ideas on how to fix this??
<% #products.each do |product_key, product_value| %>
<% #variants.each do |variant_key, variant_value| %>
<%= #child_category.name %> - <%= #subcategory.name %><br>
Products: <%= product_value %><br>
Variants: <%= variant_value %><br>
Total Products: <%= product_value + variant_value %><br>
<% end %>
<% end %>
This is the result:

Answer 1

This is not duplicating anything, this is expected behavior. It shows each product with its variants.
You're looping through two hashes, which contains 2 pairs, so the outer loop executes 2 times and the inner loop executes 2 * 2 => 4 times.
This is the expected behavior.
And if you wanted to show only a single pair, you can add if condition over there for subcategory -
i.e. I wanted to show only results where subcategory is Boys then you can use following code -
<% #products.each do |product_key, product_value| %>
<% #variants.each do |variant_key, variant_value| %>
<% if #subcategory.name == 'Boys' %>
<%= #child_category.name %> - <%= #subcategory.name %><be>
Products: <%= product_value %><be>
Variants: <%= variant_value %><be>
Total Products: <%= product_value + variant_value %><be>
<% end %>
<% end %>
<% end %>
