Question

I have two models, named as Products and Variants, in which Variant model have association
with Products as a Product have many Variants. Variant model have field named as
“available_on” … I want to implement search using two dates as check-in n checkout dates.

.

if variants for a product available for each date , check-in date to checkout date, result will map all those products and it is the result….

.
.
guide me how i should give conditions using Sunspot:solr

roughly my models are like this

product
{
product_id integer
has_many variants
}

variant
{
variant_id integer
available_on date
belongs_to product
}

check-in n checkout are the inputs for the search.

Answer 1

it will be easier to answer if you put your models in question but in general way if you have has_many relationship than you should index nested model

#variant model

searchable do

  integer :product_id
  time :check_in     
  time :check_out     

end

if you need to index something from parent has_many model you can use :multiple=>true option in this way

#product model

def variant_ids     
  variants.collect(&:id)
end

searchable do

  integer :variant_ids, :multiple=>true
  ...

end
