Plug multiple schemas

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 @forestadmin/agent v1.

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

Plug multiple schemas

A schema is an organizational layer to better structure your SQL database.

At installation, you may only choose 1 schema:

If you're not using specific schemas, you don't have to fill this advanced option.

Forest Admin can display collections from multiple schemas

To achieve this, proceed to install using 1 of your schemas. Only the models of this schema will be generated in your models directory.

Let's take a model example:

// This model was generated by Lumber. However, you remain in control of your models.
// Learn how here:
module.exports = (sequelize, DataTypes) => {
  const { Sequelize } = sequelize;
  // This section contains the fields of your model, mapped to your table's columns.
  // Learn more here:
  const Addresses = sequelize.define(
      addressLine: {
        type: DataTypes.STRING,
        field: 'address',
      addressCity: {
        type: DataTypes.STRING,
      country: {
        type: DataTypes.STRING,
      createdAt: {
        type: DataTypes.DATE,
      tableName: 'addresses',
      underscored: true,
      schema: process.env.DATABASE_SCHEMA,

  return Addresses;

On line 24, you'll notice schema: process.env.DATABASE_SCHEMA.

It uses the environment variable DATABASE_SCHEMA set in your .env file. You'll have to edit this to match your schemas. For instance, if you have 2 schemas:

DATABASE_SCHEMA_1: name_of_the_first_schema;
DATABASE_SCHEMA_2: name_of_the_second_schema;

Once this is done, follow those steps:

Step 1: Edit your current models

Because you have changed your environment variable name from DATABASE_SCHEMA to DATABASE_SCHEMA_1, you need to update it in all your models' file in the models directory (same line as line 24 in the above example).

Step 2: Create new models

For each of your other schemas' models, you'll need to create a file in models. This must be done manually and the schema line must be set to DATABASE_SCHEMA_2 as per above example.

If your other schemas have a lot of models, a quick way to generate the models is to create a another project using those other schemas (1 project for each schema).
