# Multitenancy
AshPostgres supports schema-based multitenancy:
```elixir
defmodule MyApp.Tenant do
use Ash.Resource,
data_layer: AshPostgres.DataLayer
# Resource definition...
postgres do
table "tenants"
repo MyApp.Repo
# Automatically create/manage tenant schemas
manage_tenant do
template ["tenant_", :id]
end
end
end
```
## Setting Up Multitenancy
1. Configure your repo to support multitenancy:
```elixir
defmodule MyApp.Repo do
use AshPostgres.Repo, otp_app: :my_app
# Return all tenant schemas for migrations
def all_tenants do
import Ecto.Query, only: [from: 2]
all(from(t in "tenants", select: fragment("? || ?", "tenant_", t.id)))
end
end
```
2. Mark resources that should be multi-tenant:
```elixir
defmodule MyApp.Post do
use Ash.Resource,
data_layer: AshPostgres.DataLayer
multitenancy do
strategy :context
attribute :tenant
end
# Resource definition...
end
```
3. When tenant migrations are generated, they'll be in `priv/repo/tenant_migrations`
4. Run tenant migrations in addition to regular migrations:
```bash
# Run regular migrations
mix ash.migrate
# Run tenant migrations
mix ash_postgres.migrate --tenants
```
