Download the PHP package asseco-voice/laravel-multitenancy without Composer

Multitenancy

Purpose of this repository is to enable multitenancy with multiple DB setup.

Installation

Require the package with composer require asseco-voice/laravel-multitenancy. Service provider will be registered automatically.

Setup

DB setup

Since this is a multi-DB tenancy package be sure to provide separate env values for landlord connection as well as connection for tenants.

Landlord is a separate DB connection which holds all shared migrations. The main one given through the package is tenants table which will hold configuration for all the tenants in the system. Add Landlord env variables (format is the same as native DB connection):

Use native DB connection to provide connection for tenants but comment out DB_DATABASE as this will be dynamically switched during runtime.

This means that all the tenants will be on a single connection but on separate databases. If you want to provide custom connection for some (or all) tenants, you can do so by providing that config within a DB table. More on that later.

Tenant aware commands

Some native Artisan commands are modified to provide two additional options:

• --tenant - where you can provide a tenant ID for command to run on (i.e. --tenant=1). If you omit this argument, the command will run for all tenants.
• --landlord - will assume to run on landlord connection.

Commands currently available are:

• migrate
• db:seed
• db:wipe

Migrations

Publish the migration by running:

php artisan vendor:publish --tag="asseco-multitenancy-migrations"

This will create a single migration within a migrations/landlord directory. Landlord represents a shared set of migrations which should be accessible independently of a chosen Tenant.

The default migration (tenants table) should hold all data related to tenants in the system. You are free to add other migrations there which would represent a shared set of tables across all tenants.

Migrate landlord files by running php artisan migrate --landlord

Once you have a tenants table, you can add a new tenant by manually filling out the DB or using Tinker (TODO: API + auto create). At that point, be sure to also create the database you specified in the table.

Example:

Be sure that foo database exists on the server you defined within .env. At the point you hit foo.localhost, you will see the tenant switch to that particular DB.

Separate tenant connections

To provide a tenant with a completely custom DB connection edit its configuration in DB by filling out all the db_ values in the tenants table. If one of the values is missing from the configuration, default will be used. Rest of the values will in that case be ignored.

Extending the package

Publish the configuration file by running:

php artisan vendor:publish --tag="asseco-multitenancy-config"

Extensible parts:

• tenant_resolver is the class responsible for figuring out who the current tenant is. Default resolution is by a domain. You can create a new class implementing TenantResolver interface and use it instead of the default one.

• tenant_model can be overridden, just be sure to extend the default Tenant model from the package.

• switch_tenant_tasks is an array of classes implementing SwitchTenantTask interface which are being ran when tenant is switched.

Final notes

Due to our specific use cases, this package was created as a merge of these 2 amazing multi tenancy packages:

• Spatie multi-tenancy

• Archtechx tenancy
