How to update any table from another model?

It seems you are using povit table to link the person with addresses.

Actually, you need to provide more details

• Do you have an Address model?
• Do you have any relationship between the Person & the Address model?

Assuming you have an Address model to store the addresses, you may use the following approach.

In your Person.php Model

public function addresses()
{
   return $this->belongsToMany(Address::class);
}

In your Controller:

public function store(StorePersonRequest $request)
{
   $person = Person::find($request->person_id);

   $person->addresses()->attach($request->person_address) // assuming the "person_address" returns an array

   return redirect()->route(...); // or whatever what you want to return.
}

// on the update method
public function update(UpdatePersonRequest $request, Person $person)
{
   // if you want to add new values (override the old values)
   $person->addresses()->sync($request->address); // assuming the request returns an array of values.

  // if you want to add new values without overriding the old ones
  $person->addresses()->syncWithoutDetaching($request->address);
}
