Question

I am trying to retrieve properties which has multiple amenities.

But the table structure is: properties are in property table and amenities are associated with the property.

Amenities table has:

id property_id amenity_name ....

Now i want to search the amenities that have ‘parking’ and ‘elevator’ and so on.

select property_id from amenities where name = 'parking' and name = 'elevator';

I dont want to fire a join query for this.

So can anybody save me in this situation?

Answer 1

Try this -:

   scope :amenity_type, lambda {|term|
          where("amenities.name" => term).joins(:amenities).group("amenities.property_id").having("count(amenities.name) >= #{term.size}") unless term.blank?
   }
