How to determine if a form has changes

This has been posted elsewhere, but the solution hasn't been quite clear or evident. Making a new post to continue the discussion we started in order to not hijack the original question, which was slightly different.

The isDirty() method, when applied to '$record' will always be false, as $record will be linked to the original model. When applied to an instance of a livewire component, it still seems to return false whether any field has changed or not.

What I am trying to do is this: within an action that is in a form in a resource, to have different behavior based on if there any fields that have been changed or not by the user. I was able to do this by comparing the state to the original data, but this seems a bit cumbersome and also requires formatting datetimes and boolean values, since they maybe represented slightly differently in the database versus the livewire component.

Solution

here's one option, in your EditRecord and CreateRecord page classes add:

public bool $isDirty = false;

public function updating() {
    $this->isDirty = true;
}

public bool $isDirty = false;

public function updating() {
    $this->isDirty = true;
}

Then you should be able to check it in the action callback:

->action(function ($livewire) {
  dd($livewire->isDirty);
})

->action(function ($livewire) {
  dd($livewire->isDirty);
})
