Settings & Defaults

No additional coding is required besides adding the plugin to the schema. However, the defaults may be overridden to alter the functionality of the plugin. This is done by supplying a JSON object in the following hierarchy to the plugin while attaching it to the schema:

{
    created : {
        use         : true,                    // set to false to disable
        key         : 'audit.created',         // used by mf-mongoose-dto plugin
        hide        : undefined,               // used by mf-mongoose-dto plugin
        name        : 'Created Date',          // used by mf-mongoose-dto plugin
        path        : 'ac',                    // actual path in schema
        show        : undefined                // used by mf-mongoose-dto plugin
    },
    updated : {
        use         : true,
        key         : 'audit.updated',
        hide        : undefined,
        name        : 'Updated Date',
        path        : 'au',
        show        : undefined
    },
    member : {
        use         : true,
        default     : undefined,                // generally used while seeding your database
        type        : Schema.ObjectId,          // override the data type or use uuid setting
        key         : 'audit.member',
        hide        : undefined,
        name        : 'Audit Member',
        path        : 'am',
        show        : undefined,
        uuid        : undefined                 // flags data type as UUID (uid, v1, v4)
    }
}

Note:
If desired, you may use UUID values for the Audit Member ID field by setting the uuid: property. Valid options are 'uid', 'v1', and, 'v4'. Setting this value will automatically change the dependent parameters within the schema (type, etc.). For example:

{
    member : {
        uuid : 'v4'
    }
}

Example #1: Basic Usage

Date Created and Date Updated are added automatically. Member ID may be added by default or passed in.

Logic

In the example below we are seeding the database. The optional (extended) Unique Identifier type is supplied along with the ID of the System Administrator user. None fo the values in the audit fields (ac, au, or am) were supplied after the creation of the schema.

Schema

var mongoose = require('mongoose'),
    mfAudit = require('mf-mongoose-audittrail'),
	enums    = require('../enums');

var personSchema = mongoose.Schema({

    s   : { type: String, name: 'SSN'  },

    p   : { type: String },
    f   : { type: String },
    m   : { type: String, name: 'Middle Name', key: 'name.middle' },
    l   : { type: String, name: 'Last Name', key: 'name.last' },

    bm  : { type: Number, name: 'Birth Month', key: 'dob.month' },
    bd  : { type: Number, name: 'Birth Day', key: 'dob.day' },
    by  : { type: Number, name: 'Birth Year', key: 'dob.year' }
});

personSchema.plugin(mfAudit, {
	member: {
	    uuid    : 'uid',
   		default : '40B30547A8F748EC91D57A95749E0112'
	}
);

module.exports = mongoose.model('Person', personSchema);

Result:

{
    s : '123-45-6789',

    p : 'MR'
    f : 'Joe',
    m : 'Dweezil',
    l : 'Blow',

    bm : 12,
    bd : 31,
    by : 2000,

    ac : Fri Aug 19 2016 15:35:23 GMT-0400 (EDT),   // Date Created
    au : Fri Aug 19 2016 19:14:03 GMT-0400 (EDT),   // Date Modified
    am : '40B30547A8F748EC91D57A95749E0112'         // Responsible User ID
}

Example #2: Basic Usage + the DTO Plugin)

Adding the mf-mongoose-dto plugin allows for the output of the toJSON() call to be prepared for user-facing application usage.

Logic

Adding the mf-mongoose-dto plugin extends the capabilities of the mf-mongoose-audittrail plugin for a more cosmetically pleasing and human-readable presentation.

Schema

var mongoose = require('mongoose'),
    mfAudit = require('mf-mongoose-audittrail'),
	mfDto   = require('mf-mongoose-dto'),
    enums    = require('../enums');

var GUEST = 10,
    USER  = 20,
    OWNER = 30,
    ADMIN = 40;

var personSchema = mongoose.Schema({

    s   : { type: String, name: 'SSN'  },

    p   : { type: String, name: 'Prefix', enums: enums.NamePrefix.ids },
    f   : { type: String, name: 'First Name', key: 'name.first' },
    m   : { type: String, name: 'Middle Name', key: 'name.middle' },
    l   : { type: String, name: 'Last Name', key: 'name.last' },

    bm  : { type: Number, name: 'Birth Month', key: 'dob.month' },
    bd  : { type: Number, name: 'Birth Day', key: 'dob.day' },
    by  : { type: Number, name: 'Birth Year', key: 'dob.year' }
});

personSchema.plugin(mfAudit, {
	created: {
	    hide : '< ' + USER
	}
	updated: {
	    hide : '< ' + USER
	}
	member: {
	    uuid     : 'uid',
   		 default : '40B30547A8F748EC91D57A95749E0112',
   		 show    : '>= ' + USER
	}
);
personSchema.plugin(mfDto);

module.exports = mongoose.model('Person', personSchema);

Usage

var result = person.toJSON({
    hide  : '_id',
    show  : ['bd', 'by'],
    level : USER
});

Result:

{
    prefix : {
        id : 'MR'
    },
    name : {
        first  : 'Joe',
        middle : 'Dweezil'
    },
    dob  : {
        month : 12,
        day   : 31,
        year  : 2000
    },
    audit : {
    	member  : '40B30547A8F748EC91D57A95749E0112'
    }
}

Explanation:

The Audit Fields are build out in a more human-readable hierarchy.
Some fields are hidden by the mf-mongoose-dto plugin because the hide and show settings passed into the plugin when it was added to the schema.
Other fields in the document were automatically hidden by the mf-mongoose-dto plugin because of the hide and show parameters added to the schema.

Database Seeding

Remember to set the audit.member identifier field when seeding your database. When using the default settings, the key for this field is am:. For example:

var seedMemberId = '49031586161143F5AB37AD809538A5CE';

module.exports = {
    items: [
        {
            t: 'E',
            i: '[email protected]',
            p: [
                { k: 'name', v: 'Spotless Software LLC', am: seedMemberId }
            ],
            am: seedMemberId
        },
        {
            t: 'E',
            i: '[email protected]',
            p: [
                { k: 'name', v: 'MEAN Factory', am: seedMemberId }
            ],
            am: seedMemberId
        }
    ]
};

You may also want to override the the type: setting for the audit.member field. The example above uses the 'uid' identifier type, so the plugin settings for this would be:

var externalProfileSchema = new mongoose.Schema({

    _id : String,

    t   : String,
    i   : String,

    p   : { type: [ propertySchema ] }

});
externalProfileSchema.plugin(mfAuditTrail, {
    member: {
        uuid: 'uid'
    }
});

module.exports = mongoose.model('ExternalProfile', externalProfileSchema);
