# Tenants {#tenants}
This page covers the `Stancl\Tenancy\Tenant` object. Both [creating tenants]({{ $page->link('creating-tenants') }}) and interacting with the [tenant storage]({{ $page->link('tenant-storage') }}) are covered on separate pages. This page focuses on advanced usage, which can help you with writing nicer code.
## `$data` {#data}
An associative array that mirrors the tenant's data in the actual storage. It acts as a "cache" for [tenant storage methods]({{ $page->link('tenant-storage') }}). When you call `$tenant->get('foo')`, the `$data` property is checked for `'foo'` before trying to read from the storage. Similarly, when you call `$tenant->put()`, you write both to the actual storage and to the `$data` array.
If you try to access the tenant's properties using `$tenant->foo` or `$tenant['foo']`, those calls are redirected to the `$data` array.
The `put()` call always writes to the actual storage. If you do just:
```php
$tenant->foo = 'bar';
```
The data will not be persisted until you `->save()` the `$tenant`.
## `$domains` {#domains}
An array of domains that belong to the tenant.
You may add and remove domains using the following methods:
```php
$tenant->addDomains(['foo.yourapp.com'])->save();
$tenant->addDomains('foo.yourapp.com')->save();
$tenant->removeDomains(['foo.yourapp.com'])->save();
$tenant->removeDomains('foo.yourapp.com')->save();
```
> Don't forget to `->save()` after modifying the domains!
## `run()` {#run}
The `$tenant->run()` command lets you execute a closure inside a tenant's "environment".
```php
$tenant->run(function ($tenant) {
User::create(['name' => 'Admin', 'email' => 'admin@yourapp.com', ...]);
});
```
It also lets you get data from the tenant's environment:
```php
$tenantsUserCount = $tenant->run(function ($tenant) {
return User::count();
});
```
If you need access to the tenant within the closure, it's passed as the first argument.
This feature is a safe alternative to:
```php
tenancy()->initialize($tenant);
// make some changes
tenancy()->end();
```
and it also checks if tenancy was initialized. If it was, it returns to the original tenant after running the closure.
## `$persisted` {#persisted}
This property says whether the model has saved to the storage yet. In other words, if it's `false`, it's a new instance that has not been `->save()`d yet.
## `->save()` {#save}
If no ID is set in the tenant's `$data`, it will be generated using the `UniqueIDGenerator` specified in `config('tenancy.unique_id_generator')`.
Then, if the object has been persisted, it's updated in storage. Otherwise, it's written to storage.
## `->with()` {#with}
You may fluently change the tenant's `$data` using `->with()`:
```php
$tenant->with('foo', 'bar'); // equivalent to $tenant->foo = $bar
```
Don't forget to `->save()` when you use `->with()`:
```php
$tenant->with('foo', 'bar')->with('abc', 'xyz')->save();
```
You may also use `->with<PropertyNameInPascalCase>` and it will be stored in snake case:
```php
>>> \Tenancy::find('b07aa3b0-dc68-11e9-9352-9159b2055c42')
=> Stancl\Tenancy\Tenant {#3060
+data: [
"id" => "b07aa3b0-dc68-11e9-9352-9159b2055c42",
],
+domains: [
"foo.localhost",
],
}
>>> \Tenancy::find('b07aa3b0-dc68-11e9-9352-9159b2055c42')
->withPaypalApiKey('foobar')
->save();
=> Stancl\Tenancy\Tenant {#3087
+data: [
"id" => "b07aa3b0-dc68-11e9-9352-9159b2055c42",
"paypal_api_key" => "foobar",
],
+domains: [
"foo.localhost",
],
}
```
These methods make the most sense (= sound the best) during tenant creation:
```php
// $domains = ['foo.yourapp.com', 'foo.com'];
$primary_domain = $domains[0];
$id = $primary_domain . $this->randomString(24);
Tenant::new()
->withDomains($domains)
->withPaypalApiKey('defaultApiKey');
->withId($id)
->save();
```
