snkz / mongoose-rollback Goto Github PK

I try to revert documents to a previous version which is marked by a property called _lastSavedVersion.

But when I try this:

Model.find({ edited: true }, (err, results) => {
  if (err) {
    next(err);
  }
    
  results.forEach((result) => {
    const lastSavedVersion = result._lastSavedVersion;

    result.revert(lastSavedVersion, (revertErr, hist) => {
      if (revertErr) {
        console.log('revert Error: ', revertErr);
        next(revertErr);
      }

        console.log('hist: ', hist);
      });
    });
    res.sendStatus(200);
  });
}

I get an Error saying:

{
    message: 'No matching document found for id "59e4756fc389a51c16f9fef3"',
    name: 'VersionError'
}

Any idea what I'm doing wrong or how I can make this work?

Edit: It correctly reverts the right document in the model_hist collection. But doesn't revert the original document.

Currently delta data were stored in data like this

/* 1 */
{
    "_id" : ObjectId("587a3354a185ba2f002f75df"),
    "currentVersion" : 1,
    "data" : [ 
        {
            "createdAt" : ISODate("2017-01-14T14:19:00.815Z"),
            "_id" : ObjectId("587a3354a185ba2f002f75df"),
            "_version" : 0,
            "data" : "World",
            "name" : "Hello"
        }, 
        {
            "createdAt" : ISODate("2017-01-14T14:19:00.815Z"),
            "_id" : ObjectId("587a3354a185ba2f002f75df"),
            "_version" : 1,
            "data" : "Yo",
            "name" : "Hey",
            "__v" : 0
        }
    ],
    "__v" : 0
}

Is it possible to only store changed delta data here, this jsondiffpatch may help you.

Hey,

I've been having some problems trying to get this module to work. When I don't specify a db connection when instantiating the plugin, Model.RollbackModel returns undefined and all save() methods on my models fail to do anything. However, if I specify in a conn property, either as an actual connection object (in my case, I use createConnection rather than Mongoose's global form), or as a hard coded string, I get the dreaded "Trying to open unclosed connection." error from mongoose-rollback.js:29

Any ideas?
Thanks!
Matt

Sometimes I get this error:
TypeErrornode_modules/mongoose-rollback/lib/save.js:56
TypeError · model.toObject is not a function
And this makes my server go down
Any idea about this?
