Ruby check if nil and set different value

Issue

This Content is from Stack Overflow. Question asked by Robert

How can I check if the something is nil and if its nil then use a different function to set value.

Integer($evm.root.attributes["dialog_cloud_network"]) can be nil in some cases and so I want to use a different function query_catalogitem(:cloud_network) to set value.

Example:

cloud_network_id =  Integer($evm.root.attributes["dialog_cloud_network"]) || query_catalogitem(:cloud_network). 

The above doesn’t work because cloud_network_id ends with value nil instead of getting the value from query_catalogitem(:cloud_network). How can I resolve this?
