I am trying to use a custom sql query to display different attributes for a product i.e. Size and Price. The query I have when running in console displays as it should
SELECT products.id, products.name, variant_properties.description, LEFT(variant_properties.description,1) as short_desc, variants.price FROM products
INNER JOIN product_properties ON product_properties.product_id = products.id
INNER JOIN variant_properties on product_properties.property_id = variant_properties.property_id AND variant_properties."primary" = true
INNER JOIN properties ON properties.id = product_properties.property_id AND properties.id = variant_properties.property_id AND properties.display_name = 'Size'
INNER JOIN variants on variants.product_id = products.id AND variants.id = variant_properties.variant_id
In my HAML template I have done the following
- @products.each_with_index do |product, i|
.product-list.grid-block
.small-8.grid-content.text-center
%h4= product.name.titlecase
- @sizes.each do |size|
= link_to size.short_desc, product, class: 'hollow button tiny'
%small= size.price
and in the controller
products = Product.active
# products = Product.active.includes(:variants)
product_types = nil
if params[:product_type_id].present? && product_type = ProductType.find_by_id(params[:product_type_id])
product_types = product_type.self_and_descendants.map(&:id)
end
if product_types
@products = products.where(product_type_id: product_types)
else
@products = products
end
@sizes = Product.find_by_sql("SELECT products.id, LEFT(variant_properties.description,1) as short_desc, variants.price FROM products
INNER JOIN product_properties ON product_properties.product_id = products.id
INNER JOIN variant_properties on product_properties.property_id = variant_properties.property_id
INNER JOIN properties ON properties.id = product_properties.property_id AND properties.id = variant_properties.property_id AND properties.display_name = 'Size'
INNER JOIN variants on variants.product_id = products.id AND variants.id = variant_properties.variant_id")
