I have a map of objects in my code. The objects are Alerts
and basically the root alert object is the key to an array of duplicate
So basically the map contains keys of Alert objects and they map to
arrays of fixnums.
I’m having a slight problem though accessing the arrays from the map.
My Alert extends the ActiveRecord:Base object so if I say create a map,
alertsMap, of the Alerts by their root and one of the roots has the id
then I retrieve the same Alert from the dB.
alert = Alert.find(2)
now I have a map where the alert with the id 2 maps to an array of
and also have an Alert object with id 2.
alas querying the map with the object I retrieved returns nothing.
In my Alert class I override the general comparison method <=> as such :
# Equality method. # Java Equivalent to public boolean equals(Object other) def <=>(other) alert_id <=> other.alert_id end
as I figured that this is what the map would use to compare object
passed in as keys based on their alert_ids. i.e. 2 should have compared
equally to 2.
Does anyone know if I’m doing this the right way?
Any help would be greatly appreciated.
