Bookshelf Soft Delete

This plugin works with Bookshelf.js, available here http://bookshelfjs.org, in order to introduce a soft deletion. What this means is that items will appear deleted to an end user, but will not in fact be removed from the database.

Installation

npm install bookshelf-softdelete

Then in your bookshelf configuration:

var Bookshelf = require('bookshelf')(knexconf);
Bookshelf.plugin(require('bookshelf-softdelete'));

Usage

On your bookshelf Model which you would like to mark for soft deletion mention the field name:

soft: 'FIELD_NAME' 

Please note that this will set 0(default) or 1(deleted). You can explicity specify the deleted value. It can be a number or string

soft: {
    'field': 'FIELD_NAME',
    'val': {'normal': 1, 'deleted': 0}
},

If you wish to disable soft delete for a given operation, e.g., fetch, simply pass an object with softDelete: false to that operation.

YourModel.where("id", searchId)
    .fetch({softDelete: false})

If you need to restore something which has been soft deleted, model.restore will do this.

Usage with a custom initialize function

This package has an initialize function that wires everthing up. If you declare a custom initialize function, you need to make sure to call the initialize function on the prototype from the custom initialize function in order for everything to work properly.

var repository = require('./repo');

module.exports = repository.Model.extend({
  tableName: 'users',
  soft: 'is_valid',

  initialize: function() {
    this.on('saving', this.validate);
    repository.Model.prototype.initialize.apply(this, arguments);
  },

  validate: function() {
    ...
  }
});
