Upgrade to v4

The purpose of this note is to help developers to upgrade their agent from v3 to v4. Please read carefully and integrate the following breaking changes to ensure a smooth update.​

PreviousUpgrade to v5NextUpgrade to v3

Last updated 1 year ago

Was this helpful?

Please be sure of your agent type and version and pick the right documentation accordingly.

This is the documentation of the forest-express-sequelize and forest-express-mongoose Node.js agents that will soon reach end-of-support.

forest-express-sequelize v9 and forest-express-mongoose v9 are replaced by v1.

Please check your agent type and version and read on or switch to the right documentation.

This is still the latest Ruby on Rails documentation of the forest_liana agent, you’re at the right place, please read on.

This is the documentation of the django-forestadmin Django agent that will soon reach end-of-support.

If you’re using a Django agent, notice that django-forestadmin v1 is replaced by v1.

If you’re using a Flask agent, go to the v1 documentation.

Please check your agent type and version and read on or switch to the right documentation.

This is the documentation of the forestadmin/laravel-forestadmin Laravel agent that will soon reach end-of-support.

If you’re using a Laravel agent, notice that forestadmin/laravel-forestadmin v1 is replaced by v3.

If you’re using a Symfony agent, go to the v1 documentation.

Please check your agent type and version and read on or switch to the right documentation.

Upgrade to v4

Upgrading to v4

Before upgrading to v4, consider the below breaking changes.

As for any dependency upgrade, it's very important to test this upgrade in your testing environments. Not doing so could result in your admin panel being unusable.

To upgrade to v4, simply run:

npm install forest-express-sequelize@4.0.2
npm install forest-express-mongoose@4.1.2

In case of a regression introduced in Production after the upgrade, a rollback to your previous agent version 3 is the fastest way to restore your admin panel.

Breaking changes

New JWT authentication token

The information format of the session token have changed in v4.

You could be impacted if you use the user session in Smart Action controllers or Smart Routes

Calling req.user in v3

v3 format
{
  "id": "172",
  "type": "users",
  "data": {
    "email": "angelicabengtsson@doha2019.com",
    "first_name": "Angelica",
    "last_name": "Bengtsson",
    "teams": ["Pole Vault"],
  },
  "relationships": {
    "renderings": {
      "data": [{
        "type": "renderings",
        "id": "4998",
      }],
    },
  },
  "iat": 1569913709,
  "exp": 1571123309
}

Calling req.user in v4

v4 format
{
  "id": "172",
  "email": "angelicabengtsson@doha2019.com",
  "firstName": "Angelica",
  "lastName": "Bengtsson",
  "team": "Pole Vault",
  "renderingId": "4998",
  "iat": 1569913709,
  "exp": 1571123309
}

Consequently, the user information is now accessible as described below:

Property
v3
v4

email

req.user.data.email

req.user.email

first name

req.user.data.first_name

req.user.firstName

last name

req.user.data.last_name

req.user.lastName

team

req.user.data.teams[0]

req.user.team

rendering id

req.user.relationships.renderings.data[0].id

req.user.renderingId

New filters query parameters format

The query parameters sent for filtering purposes have changed in v4.

You could be impacted if you have custom filter implementations.

Below are a few example of the new filter conditions format you can access usingreq.params.filters:

Simple condition example:
{
  "field": "planLimitationReachedAt",
  "operator": "previous_year_to_date",
  "value": null
}
Multiple conditions example:
{
  "aggregator": "and",
  "conditions": [{
    "field": "planLimitationReachedAt",
    "operator": "previous_year_to_date",
    "value": null
  }, {
    "field": "planLimitationStatus",
    "operator": "equal",
    "value": "warning"
  }]
}

MongoDB

This section is dedicated to breaking changes on projects using MongoDB connections.

MongoDB version support

The minimal version supported by the agent v4 is MongoDB v3.2 (December 2015).

If your project uses an older MongoDB version, you should not upgrade to v4.

The way the agent implements the resources filtering changed and this new implementation uses features that does not exist in MongoDB versions older than 3.2.

Smart Field search implementation

The Smart Field search implementation has changed:

  • The function signature now has only one search parameter.

  • The expected value to be returned is a hash of the conditions (instead of the query object).

See the following implementation migration example:

Before (v3)
 search(query, search) {
  let names = search.split(' ');
​
  query._conditions.$or.push({
    firstname: names[0],
    lastname: names[1]
  });
​
  return query;
}
After (v4)
search(search) {
  let names = search.split(' ');
​
  return {
    firstname: names[0],
    lastname: names[1]
  };
}

Condition operator changes

For consistency reasons, contains, starts with and ends with operators are now case sensitive.

Smart relationships reference syntax

Before (v3)
reference: 'Address';
After (v4)
reference: 'Address._id';

Important Notice

Agent logout

A consequence of the new session token format is:

Once an agent v4 deployed, all users of your project will be automatically logged out and be forced to re-authenticate to generate a newly formatted token. ​
