SoftDelete Loopback Mixin

This module is designed for the Strongloop Loopback framework. It allows entities of any Model to be "soft deleted" by adding deletedAt and _isDeleted attributes. Queries following the standard format will no return these entities; they can only be accessed by adding { deleted: true } to the query object (at the same level as where, include etc).

This mixin was recoded since the current available softdelete mixin is not working in Node.js v4.x.x, probably caused by ES6. This code is forked from https://github.com/gausie/loopback-softdelete-mixin

To implement copy this file to mixins folder or clone this private repository (requires adding the package folder path to mixins inside model-config json file), and add "SoftDelete": true in mixins on YourModel.json file.

To delete a row or data, don't use destroyAll etc., use YourModel.delete

To find data that is considered deleted, add includeDeleted: true in where filter

Install

  npm install --save git+ssh://[email protected]/letscomunicadev/loopback-lets-soft-delete-mixin.git#v0.0.2

Updates

Made a modification? Test it at least in one project before submiting a version. It still needs unit testing and CI with projects. After everything seems perfectly up-to-date, run the following steps:

1. Commit and push your updates using Let's Bitbucket credentials

2. Change and commit a new tag version (always check and update the last version here and in package.json):

$ git tag -a vX.X.X -m "version_message"

3. Push the new tag version to remote repository:

$ git push origin vX.X.X  # Version needs to be the same from commit

4. Run npm installation with the newest version:

  npm install --save git+ssh://[email protected]/letscomunicadev/loopback-lets-soft-delete-mixin.git#vX.X.X

Configure

To use with your Models add the mixins attribute to the definition object of your model config.

  {
    "name": "Widget",
    "properties": {
      "name": {
        "type": "string",
      },
    },
    "mixins": {
      "SoftDelete" : true,
    },
  },

There are a number of configurable options to the mixin. You can specify alternative property names for deletedAt and _isDeleted, as well as configuring deletion to "scrub" the entity. If true, this sets all but the "id" fields to null. If an array, it will only scrub properties with those names.

  "mixins": {
    "SoftDelete": {
      "deletedAt": "deletedOn",
      "_isDeleted": "isDeleted",
      "scrub": true,
    },
  },

Retrieving deleted entities

To run queries that include deleted items in the response, add { deleted: true } to the query object (at the same level as where, include etc).
