Restangular - _.contains() is not a function

Question

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?

Answer 1

If you have not specified the entry for lodash explicitly and this gets installs as a dependency of restangular, you can uninstall both of them and reinstall lodash (3.10.1) to fix the issue.

bower uninstall restangular
bower uninstall lodash
bower install --save lodash#3.10.1
bower install --save restangular

This way you would not need an entry into the bower.json file.

Answer 2

Couldn't you put this in app.js

// If Restangular ever updates to lodash 4.0 remove this.
_.contains = _.includes

Answer 3

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"
