mongoose-deleted v1.5.0

mongoose-deleted

a soft-delete implementation utilizing mongoose middleware

usage

var mongoose = require('mongoose');
var mongoose_deleted = require('mongoose-deleted');
var user = new mongoose.Schema({ name: String });
mongoose_deleted(user);
user = mongoose.model('user', user);

var name = "John Q Public";
var user1 = new user({ name : name });

user1.save(function() {
    user.findOne({ name : name }, function(err, doc) {
        if (err || !doc) console.log('failed to find document');
        doc.delete(function(err) {
            user.findOne({ name: name }, function() {
                if (!doc) console.log('soft delete worked');
            })
        });
    });
});

documents

mongoose-deleted utilizes mongoose middleware to transparently modify queries to select for documents that are not { deleted: true }. Documents that are .delete()-ed will not be returned. To explicitly return documents that are deleted:

schema.find({ deleted: true }, function(err, docs) {
    // ...
});

Additionally, the deleted boolean property is set by default to not be selected/returned on a document.

To have deleted normally returned:

schema.plugin(mongoose_deleted, { select : true });

To have the deleted property included, in addition to the normal properties:

schema.findOne(query).select('+deleted').exec(function(err, doc) {
    console.log(doc.deleted);
});

Or, to retrieve the deleted property only on a particular query, manually select for it:

schema.findOne({}, { deleted : 1 }, function(err, doc) {
    console.log(doc.deleted);
});

toJSON

By default, mongoose-deleted hides the deleted property on doc.toJSON(). This is configurable in the options:

schema.plugin(mongoose_deleted, { toJSON : true });

This can be overriden in a toJSON() call:

var json = doc.toJSON({ deleted : true });

history

mongoose-deleted allows an optional integration with mongoose-history-log by passing in the options:

mongoose_deleted(schema, { history: true });

This will automatically insert a { status: 'deleted' } object with the current time.
