This is a really simple question, but I'm having trouble with the syntax. Rails 4, Ruby 2.
Have the following code working to serialize some records and dump them into geo json:
module Serializers
class GeoUser < ActiveModel::Serializer
attributes :type, :geometry, :properties
def type
'Feature'
end
def geometry
{
type: 'Point',
coordinates: [object.longitude, object.latitude]
}
end
def properties
{
name: object.full_name,
address: object.full_address,
:'marker-color' => object.marker_color,
:'marker-symbol' => object.marker_symbol,
:'marker-size' => object.marker_size
}
end
end
end
My problem is sometimes object.longitude, object.latitude are null/nil and I would like to set them to 0. Simple conditional statement, something like || 0, but I can't seem to get the syntax correct.
Suggestions, please :)
Thank you!
object.longitude || 0
object.longitude || 0
will work, as will object.longitude.to_f
( nil.to_f
returns 0.0).
