If you have recently updated restangular through bower it will have installed the latest lodash - the new 4.0. However this is a problem as restangular/angular now throws the error - "_.contains() is not a function."
How do you solve?
The solution is very simple - you need to tell restangular to use a lower version than the newest lodash - 3.10.0
Through bower.json
"lodash": "~3.10.0"
