Causer Resolver
===============

###  On this page

1. [ resolve ](#content-resolve)
2. [ resolveUsing ](#content-resolveusing)
3. [ setCauser ](#content-setcauser)

This class is registered as singleton and will allow you to set causer for activity globally or per action basis.

**Note that** Overriding causer using `setCauser` method takes priority over overriding the resolver using `resolveUsing` method.

```
CauserResolver::setCauser(User::find(1));

$log = activity()->log('log look mom, I did something...');
$log->causer; // User Model with id of 1
```

resolve
-----------------------------------------------------------------------------

```
/**
 * Resolve causer based different arguments first we'll check for override closure
 * Then check for the result causer if it valid. In other case will return the
 * override causer defined by the user or delegate to the getCauser() method
 *
 * @param Model|int|null $subject
 * @return null|Model
 * @throws InvalidArgumentException
 * @throws CouldNotLogActivity
 */
public function resolve(Model | int | string | null $subject = null) : ?Model;
```

resolveUsing
--------------------------------------------------------------------------------------------

```
/**
 * Override the resolver using callback
 */
public function resolveUsing(Closure $callback): static;
```

setCauser
-----------------------------------------------------------------------------------

```
/**
 * Override default causer
 */
public function setCauser(?Model $causer): static;
```
