DeprecationWarning: collection.count is deprecated

[yohanesgultom]

I use Node v8.11.1 and these packages:

"mongoose": "^5.2.2",
"mongoose-paginate": "^5.0.3"

And this get this warning during execution of paginate():

(node:9893) DeprecationWarning: collection.count is deprecated, and will be removed in a future version. Use collection.countDocuments or collection.estimatedDocumentCount instead

Even I have the same error

Same problem here and because I'm not sure if there will be any update here, I have created small service on base this library, used in schema on the same principle but return promise and using only page, sort and limit, maybe it will help -

function paginate(query, options) {
    query   = query || {};
    options = Object.assign({}, paginate.options, options);

    const sort  = options.sort;
    const limit = options.hasOwnProperty('limit') ? options.limit : 10;
    const page  = options.page || 1;
    const skip  = options.hasOwnProperty('page') ? ((page - 1) * limit) : 0;
    const docs = limit
     ? this.find(query).sort(sort).skip(skip).limit(limit).exec()
     : query.exec();
    const countDocuments = this.countDocuments(query).exec();

    return Promise.all([docs, countDocuments]).then(function(values) {
      return Promise.resolve({
        docs:  values[0],
        total: values[1],
        limit: limit,
        page: page,
        pages: Math.ceil(values[1] / limit) || 1
      })
    });
}

module.exports = function(schema) {
    schema.statics.paginate = paginate;
};

module.exports.paginate = paginate;

Same problem. I have forked the project (from version-5.0.3) to fix the warning.

npm install git://github.com/zerok78/mongoose-paginate.git#version-5.0.4 -S

My approach
\node_modules\mquery\lib\collection\node.js:50
NodeCollection.prototype.count = function(match, options, cb) {
this.collection.count(match, options, cb);
};

change :

NodeCollection.prototype.countDocuments = function(match, options, cb) {
this.collection.countDocuments(match, options, cb);
};

\node_modules\mongoose\lib\query.js:1950
this._collection.count(conds, options, utils.tick(callback));

change :

this._collection.countDocuments(conds, options, utils.tick(callback));

Still the same issue!

I see DaviRJ fixed this 4 days ago... how do I update mongoose-paginate so that this fix is included in my node backend?

doing npm update mongoose-paginate does not do anything. sorry for the ignorance and thanks for the help!

[AmrSaber]

@bitfede He didn't, there are 11 tests failing, so his branch is not merged.

Is there any fix to this?

[lechuit]

Is there any fix to this?

in:
node_modules/mongoose/lib/query.js

• this._collection.count(conds, options, utils.tick(callback));

how to fix:
this._collection.countDocuments(conds, options, utils.tick(callback));

[AmrSaber]

@lechuit,That's not a proper solution, will need to fix it each time node modules are generated.

@paulbertil, I would suggest using mongoose-paginate-v2 instead.

Thank's @AmrSaber

This is Work , But How Can We Trust This ? Because in The Server or docker container we Can Not Access To this file
i think we should tell this problem to mongoose Contributors to fix this on next version
