How to create { x = y | y = z | z = 0 } block dynamically from hash?

Question

Although the context is likely irrelevant, I'm using the Chewy gem to filter Elasticsearch results using this code:

scope = scope.filter {
      (send('facet_properties').send(property_ids[0], :or) == val.map(&:to_i)) |
          (send('facet_properties').send(property_ids[1], :or) == val.map(&:to_i))
    }

I'm looking for a way to loop through each element in property_ids rather than calling property_ids[0], property_ids[1], etc., separated by an or individually. In actual use property_ids will not be a fixed length.

Not sure exactly what your structure looks like or exactly what you are trying to achieve but have you tried something like this?

vals = val.map(&:to_i)
prop_hash = Hash[property_ids.map{|prop| [prop,vals]}]
# alternately prop_hash = property_ids.each_with_object({}){|prop,obj| obj[prop] = vals}
scope.filter(facet_properties: {prop_hash}).filter_mode(:or)

Since chewy has a #filter_mode method to set the join type for where conditions it seems like this should work for you.
