Mongoose Plugin Meta

This plugin enables soft deletion of documents, history of updates and date of creation in MongoDB. It creates new functions that act like middlewares. At any time, it is possible to use the provided functions by Mongoose.

Installation

$ npm install mongoose-plugin-meta-nt --save

Documentation

Example with TagModel

• Tag.js

const mongoose = require('mongoose');
const metaPlugin = require('mongoose-plugin-meta-nt');

const tagSchema = new mongoose.Schema(
{
  label: {type: String, required: true}
},
{
  collection: "tags"
});

// Add plugin to the schema
tagSchema.plugin(metaPlugin.metaManager, {entity: false});

const Tag = mongoose.model('Tag', tagSchema);

### Statics

createMeta(obj, user, entities_id = []);

findMeta(obj = {}, user = {}, arrPopulate = [], entity_filter = null);
findOneMeta(obj, user = {}, arrPopulate = [], entity_filter = null);
findByIdMeta(id, user = {}, arrPopulate = [], entity_filter = null);
countMeta(obj = {}, user = {}, entity_filter = null);


findOneAndUpdateMeta(obj, newObj, user, entity_filter = null);
findByIdAndUpdateMeta(id, obj, user, entity_filter = null);


findOneAndDeleteMeta(obj, user, isSoftDelete = true, entity_filter = null);
findOneAndRemoveMeta(obj, user, isSoftDelete = true, entity_filter = null);
findByIdAndRemoveMeta(id, user, isSoftDelete = true, entity_filter = null);
findByIdAndDeleteMeta(id, user, isSoftDelete = true, entity_filter = null);
deleteOneMeta(obj, user, isSoftDelete = true, entity_filter = null);
deleteMeta(obj, user, isSoftDelete = true, entity_filter = null);

// Get all documents
findWithDeleted(obj = {}, user = {}, arrPopulate = [], entity_filter = null);
findOneWithDeleted(obj, user = {}, arrPopulate = [], entity_filter = null);
countWithDeleted(obj = {}, user = {}, entity_filter = null);


// Search

// Filter the given fields with the query value.
simpleSearch(query, fields, user = {}, entity_filter = null); //  (NOT WORKING FOR NOW)

Methods

updateMeta(newObj, user);

Queries

pagination(offset, limit);
projection(obj = null, showMeta = false, showVersion = false)

Usage

const user =
{
  id: "5b01a8ab8337ed5bfb21f7c6"
};

const id = "5b01a8ab8337ed5bfb21f1a1";

// Find - Promise
let data  = await Tag.findMeta({label: "Test"});
let data = await Tag.findOneMeta({label: "Test"});
let data = await Tag.findByIdMeta(id);

// Find - Projection
let data = await Tag.findOneMeta({label: "Test"}).projection(); // Will unselect 'meta' and '__v' fields
let data = await Tag.findOneMeta({label: "Test"}).projection({label2: 0}); // Will unselect 'label2', 'meta' and '__v' fields
let data = await Tag.findOneMeta({label: "Test"}).projection({label2: 1}); // Will select 'label2' and disabled others (MongoDB behavior) 

// Count - Promise
let data = await Tag.countMeta({label: "Test"});

// Create - Promise
let data = Tag.createMeta({label : "Test"}, user, entity_id);

// Update - Promise
let data = await Tag.findOneAndUpdateMeta({_id: id}, {label: "Custom"}, user);
let data = await Tag.findByIdAndUpdateMeta(id, {label: "CustomFindByIdUpdate"}, user);
let data = await Tag.updateMeta({label: "CustomUpdate"}, user);

// Delete - Promise
let data = await Tag.findOneAndRemoveMeta({label: "Test2"}, user);
let data = await Tag.findOneAndRemoveMeta({label: "Test3"}, user);
let data = await Tag.findByIdAndRemoveMeta(id, user);
let data = await Tag.findByIdAndDeleteMeta(id, user);
let data = await Tag.deleteOneMeta({}, user);
let data = await Tag.deleteMeta({}, user);
// Set to true for soft deletion. It is possible to set to false if you want real deletion 


// Find deleted documents - Promise
let data = await Tag.findDeleted({label: "Test"});
let data = await Tag.findOneDeleted({label: "Test2"});
let data = await Tag.countDeleted({label: "Test"});

Produced document

{ 
  "_id": "5b1995a5a87a731a94aa0abe",
  "label": "Test",
  "meta": 
  {
    "entities_id": [],
    "created":
    {
      "date": "2018-06-07T20:29:25.397Z",
      "user": "5b01a8ab8337ed5bfb21f7c6"
    },
    "deleted":
    {
      "date": "2018-06-07T20:38:06.762Z",
      "user": "5b01a8ab8337ed5bfb21f7c6"
    },
    "updated":
    [
      {
    	  "date": "2018-06-07T20:30:50.370Z",
          "user": "5b01a8ab8337ed5bfb21f7c6",
          "_id": "5b199906252b8d1ef4def526"
      }
    ]
  }
}

The _id is created in every items of the array.

## Entity filtering It is possible to enable the entity_id filtering :

• Set to true in the Model : tagSchema.plugin(metaPlugin.metaManager, {entity: true});
• If for any reason, the entity property is set to false in the model definition, it is possible to force the entity filtering by adding the parameter true in all functions.
• Set a value to the property entity_id in your user object.
• Put the user object in parameter of all functions :

const entities_id = ["5b01a8ab8337ed5bfb21f7c6"];

const user =
{
  id: "5b01a8ab8337ed5bfb21f7c6",
  entities_id: ["5b01a8ab8337ed5bfb21f7c2", "5b01a8ab8337ed5bfb21f7c6"]
};

const id = "5b01a8ab8337ed5bfb21f1a1";

// Find - Promise
let data  = await Tag.findMeta({label: "Test"}, user);
// if need to force the entity filtering : Tag.findMeta({label: "Test"}, user, true);
let data = await Tag.findOneMeta({label: "Test"}, user);
let data = await Tag.findByIdMeta(id, user);

// Count - Promise
let data = await Tag.countMeta({label: "Test"});

// Create - Promise
let data = Tag.createMeta({label : "Test"}, user);

// Update - Promise
let data = await Tag.findOneAndUpdateMeta({_id: id}, {label: "Custom"}, user);
let data = await Tag.findByIdAndUpdateMeta(id, {label: "CustomFindByIdUpdate"}, user);
let data = await Tag.updateMeta({label: "CustomUpdate"}, user);

// Delete - Promise
let data = await Tag.findOneAndRemoveMeta({label: "Test2"}, user);
let data = await Tag.findOneAndRemoveMeta({label: "Test3"}, user);
let data = await Tag.findByIdAndRemoveMeta(id, user);
let data = await Tag.findByIdAndDeleteMeta(id, user);
let data = await Tag.deleteOneMeta({}, user);
let data = await Tag.deleteMeta({}, user);
// Set to true for soft deletion. It is possible to set to false if you want real deletion 


// Find deleted documents - Promise
let data = await Tag.findDeleted({label: "Test"}, user);
let data = await Tag.findOneDeleted({label: "Test2"}, user);
let data = await Tag.countDeleted({label: "Test"}, user);
