Delete Only On Update?

[Justin Noel]

In http://jmdobry.github.io/angular-cache/configuration.html#onexpire under "Another Example", the docs show using `newCache.get` with a callback function.  This callback would be called if the cache is expired.  However, this does not work.  Instead, I get this error :

Error: AngularCache.get(key, options): options: must be an object!
at j.get (http://localhost:8000/js/lib/angular-cache-2.2.0.min.js:10:9935)

I believe that this means, it should have been passed an object like " { onExpire : function( key, value) { ...  })"

However, I can't get that to work either.

Can you help with an explanation of how to get this to work?

Thanks,

For example, I have tried this:

    var invitationsCache = $angularCacheFactory('invitationsCache', {

        maxAge          : 1000,           // Items added to this cache expire after 5 minutes.

        recycleFreq     : 20000,            // Check for expiry every 20 seconds

        deleteOnExpire  : 'passive',       // Items will be deleted from this cache right when they expire.

        storageMode     : 'localStorage',

        verifyIntegrity : true

    });

        var isGoodThisYear = true;

        var value = invitationsCache.get('invitations',

            { onExpire : function (key, value) {

                console.log('It has expired!');

                if (isGoodThisYear) {

                    console.log('Just putting them back');

                    invitationsCache.put(key, value);

                } else {

                    console.log('Going to get new');

                    $http.get(invitations).success(function (data) {

                        invitationsCache.put(key, data);

                    });

                }

            }

        });

 

However, the onExpire never gets called.

I've worked out my problem from the example below.  However, the documentation still needs to be fixed.  It needs to show that the callback is an Object, not just a function.

Sorry about the documentation being out of date. It previously was just a function, but now an object. I'll get the documentation fixed. Thanks.

The documentation should be clearer now.

I don't really see any change to the documentation.  It still just shows the second argument to newCache.get being a function:
