Track changes to your models, for auditing or versioning. See how a model looked at any stage in its lifecycle, revert it to any version, or restore it after it has been destroyed.

npm install --save sequelize-paper-trail
Note: the current test suite is very limited in coverage.
Sequelize Paper Trail assumes that you already set up your Sequelize connection, for example, like this:
var Sequelize = require('sequelize');
var sequelize = new Sequelize('database', 'username', 'password');
then adding Sequelize Paper Trail is as easy as:
var PaperTrail = require('sequelize-paper-trail')(sequelize, options={});
PaperTrail.defineModels({});
which loads the Paper Trail library, and the defineModels()
method sets up a Revisions
and RevisionHistory
table. Then for each model that you want to keep a paper trail you simply add:
Model.hasPaperTrail();
var Sequelize = require('sequelize');
var sequelize = new Sequelize('database', 'username', 'password');
var PaperTrail = require('sequelize-paper-trail')(sequelize, options || {});
PaperTrail.defineModels();
var User = sequelize.define('User', {
username: Sequelize.STRING,
birthday: Sequelize.DATE
});
User.hasPaperTrail();
Paper Trail supports various options that can be passed into the initialization. The following are the default options:
// Default options
var options = {
exclude: [
'id',
'createdAt',
'updatedAt',
'deletedAt',
'created_at',
'updated_at',
'deleted_at'
],
revisionAttribute: 'revision',
revisionModel: 'Revision',
revisionChangeModel: 'RevisionChange',
enableRevisionChangeModel: false,
underscored: false,
underscoredAttributes: false,
defaultAttributes: {
documentId: 'documentId',
revisionId: 'revisionId'
},
userModel: 'User',
enableCompression: false,
enableMigration: true,
enableStrictDiff: true,
continuationNamespace: 'com.name-space',
continuationKey: 'userId'
};
Option | Type | Default Value | Description |
---|---|---|---|
[debug] | Boolean | false | Enables logging to the console. |
[exclude] | Array | ['id', 'createdAt', 'updatedAt', 'deletedAt', 'created_at', 'updated_at', 'deleted_at', [options.revisionAttribute]] | Array of global attributes to exclude from the paper trail. |
[revisionAttribute] | String | 'revision' | Name of the attribute in the table that corresponds to the current revision. |
[revisionModel] | String | 'Revision' | Name of the model that keeps the revision models. |
[revisionChangeModel] | String | 'RevisionChange' | Name of the model that tracks all the attributes that have changed during each create and update call. |
[enableRevisionChangeModel] | Boolean | false | Disable the revision change model to save space. |
[underscored] | Boolean | false | The [revisionModel] and [revisionChangeModel] have 'createdAt' and 'updatedAt' attributes, by default, setting this option to true changes it to 'created_at' and 'updated_at'. |
[underscoredAttributes] | Boolean | false | The [revisionModel] has a [defaultAttribute] 'documentId', and the [revisionChangeModel] has a [defaultAttribute] 'revisionId, by default, setting this option to true changes it to 'document_id' and 'revision_id'. |
[defaultAttributes] | Object | { documentId: 'documentId', revisionId: 'revisionId' } | |
[enableCompression] | Boolean | false | Compresses the revision attribute in the [revisionModel] to only the diff instead of all model attributes. |
[enableMigration] | Boolean | false | Automatically adds the [revisionAttribute] via a migration to the models that have paper trails enabled. |
[enableStrictDiff] | Boolean | true | Reports integers and strings as different, e.g. 3.14 !== '3.14' |
[continuationNamespace] | String | 'com.nameSpace' | Name of the name space used with the continuation-local-storage module. |
[continuationKey] | String | 'userId' | The continuation-local-storage key that contains the user id. |
