Super Awesome! When a source field (for example a `BelongsTo` relation) changes in a Nova form, the prefiller field looks up the selected model and fills itself with a value taken from that model — either an attribute or a method on it. Installation ------------ [](#installation) Install the package via Composer: ``` composer require marshmallow/prefiller-field ``` The package registers its service provider automatically through Laravel's package discovery, so there is nothing else to set up. Usage ----- [](#usage) Use the prefiller fields inside a Nova resource's `fields()` method. Point each field at the source field with `sourceField()`, tell it which model to look up with `sourceModel()`, and choose the attribute or method to copy with `prefillWith()`. ``` use Laravel\Nova\Fields\BelongsTo; use Marshmallow\PrefillerField\PrefillerText; use Marshmallow\PrefillerField\PrefillerCurrency; public function fields(Request $request) { return [ BelongsTo::make('Product')->nullable()->searchable(), PrefillerText::make('Test', 'field_2') ->sourceField('product') ->sourceModel(\Marshmallow\Product\Models\Product::class) ->prefillWith('name'), // This can be a field or a method on your target resource PrefillerCurrency::make('Test 3', 'field_3') ->sourceField('product') ->sourceModel(\Marshmallow\Product\Models\Product::class) ->prefillWith('price') ->currency('EUR') ->default(0) ->nullable(), ]; } ``` ### Available methods [](#available-methods) Every prefiller field inherits the standard Nova field methods plus the following helpers from the `Prefillable` trait: MethodDescription`sourceField($source_field)`The attribute of the field that triggers the prefill (for example the `BelongsTo` relation).`sourceModel($source_model)`The fully-qualified model class that is looked up when the source field changes.`prefillWith($prefill_with)`The attribute or method on the looked-up model whose value is used to prefill the field.`allowUpdatingFilledFields()`Re-check for new values even when the target field already has content (by default a filled field is left untouched).`fieldType($type)`Override the field type passed to the front-end component.### Extra methods [](#extra-methods) If you want the prefiller to check for new values, even if the target field is already filled with content, you can call the method `allowUpdatingFilledFields()`. ### Supported fields [](#supported-fields) Currently we have only implemented the `Text` and `Currency` fields because we needed them in a project for a customer. We will add more in the coming months. Feel free to send a pull request if you need another field for your project. - `Marshmallow\PrefillerField\PrefillerText` — extends Nova's `Text` field. - `Marshmallow\PrefillerField\PrefillerCurrency` — extends Nova's `Currency` field.
