PR - Slug Field

[gbrits]

Pseudo pull request I guess - inside of the Slug field:

The showCustomizeButton method doesn't exist.

/**
 * Set whether or not the customize button is visible / used to enable slug editing.
 *
 * @param  boolean  $showCustomizeButton
 * @return $this
 */
public function showCustomizeButton($showCustomizeButton)
{
    $this->showCustomizeButton = $showCustomizeButton;
    $this->customizeButtonExplicitlySet = true;
    return $this;
}

Adding new public variable at the top:
public $customizeButtonExplicitlySet = false;

Then adjust one line inside of jsonSerialize():

/**
 * Prepare the element for JSON serialization.
 *
 * @return array<string, mixed>
 */
public function jsonSerialize(): array
{
    $request = app(NovaRequest::class);

    if ($request->isUpdateOrUpdateAttachedRequest()) {
        $this->readonly();
+        if($this->customizeButtonExplicitlySet === false) $this->showCustomizeButton = true;
    }

    return array_merge([
        'updating' => $request->isUpdateOrUpdateAttachedRequest(),
        'from' => $this->from instanceof Field ? $this->from->attribute : str_replace(' ', '_', Str::lower($this->from)),
        'separator' => $this->separator,
        'showCustomizeButton' => $this->showCustomizeButton,
    ], parent::jsonSerialize());
}

This will allow users to control whether or not the Customize button appears next to a slug, even in editing, based on the user's reasoning/criteria. In my instance I needed to admin-protect certain slugs.

$admin_protected_slugs = [
    'about',
    'contact'
];

...

Slug::make('Slug')->from('Title')->separator('-')
->showCustomizeButton(!(boolean)in_array($this->resource->slug, $admin_protected_slugs))
->withMeta($page_meta)->hideFromIndex()->sortable(),
