Adding `updated_at` to `$dontVersionable` results in error when calling `diff()`

[CamilleScholtz]

I don't really want to track updated_at, so I added it to the $dontVersionable variable in the model, however when calling the diff() method it gives me the following error:

Undefined array key "updated_at"

@mansoorkhan96 Please take a look. thanks.

Please provide complete code examples to help us help you.

@overtrue Seems like there are two issues with snapshot.

1. Initial version does not contain any attributes, so its always null
2. New versions are stored even though the $versionable attributes are not dirty

[mansoorkhan96]

@overtrue I think maybe this is happening because user aaded the DIFF strategy initially but then switched to Snapshot?

So one version which was created using DIFF might have a few attributes and the other one created with Snapshot would ofcourse have all the $versionable attributes. So thats where the diff() method complains about not having attributes in hand.

I am able to reproduce.
Its the DIFF strategy which adds non $versionable attributes

ok, may be we can ignore this, or add some notes in readme.

@overtrue I beleive there shouldnt be the DIFF strategy it should only be snapshot. which stores all attributes by default unless you specifiy $versionable.

[overtrue]

so, let's drop the strategy feature? ok?

[mansoorkhan96]

@overtrue yes that sounds good. plus a good mechanism to see if the changes are valid to create a new version.

plus some strictness maybe. throw an exception if user is using both properties i.e $versionable and $dontVersionfields. They should be using either of them?

If you want support both then maybe a way to get the intersection of both
