Nova Ajax Select

Ajax populated select fields based on the values of other fields and when they change.

Install

composer require dillingham/nova-ajax-select

Usage

Specify a request url & optionally the parent($attribute) to watch & trigger the ajax select:

use NovaAjaxSelect\AjaxSelect;

BelongsTo::make('Company'),

AjaxSelect::make('User')
    ->get('/api/company/{company}/users')
    ->parent('company'),

Add the field for index & detail views display. AjaxSelect is for forms only

BelongsTo::make('User')->exceptOnForms(),

Request Url:

In the above example, we say company is the parent.

The {company} url parameter will equal the selected Company field value.

Response Format:

The select field expects a value & display. Map your results like so:

Route::get('api/company/{company}/users', function($company_id) {

    $company = \App\Company::find($company_id);

    return $company->users->map(function($user) {
        return [ 'value' => $user->id, 'display' => $user->name ];
    });
})->middleware(['nova']);

Make children depend on other children

City makes a request based on State, which makes a request based on Country:

Select::make('Country')
    ->options([]),

AjaxSelect::make('State')
    ->get('/api/country/{country}/states')
    ->parent('country'),

AjaxSelect::make('City')
    ->get('/api/state/{state}/cities')
    ->parent('state'),

Make multiple children depend on one parent

File & Comment will both make a request based on Project

BelongsTo::make('Project'),

AjaxSelect::make('File')
    ->get('/{project}/files')
    ->parent('project'),

AjaxSelect::make('Comment')
    ->get('/{project}/comments')
    ->parent('project'),
