Zielsetzung

Kleine Tipps zur Verwendung von LaraKnife.

Moduländerungen

In den Beispielen wird das Modul Notes verwendet.

Zusätzliches Attribut

Es soll das Attribut "info" ergänzt werden:

Zu tun:

• Datenbank erweitern:

php artisan make:migration add_notes_info --table=notes

Die entstehende Datei bearbeiten:

public function up()
{
    Schema::table('notes', function ($table) {
        $table->string("info");
    });
}

• Auflistung der möglichen Datentypen: Datenbank-Laravel#Felddefinitionen

php artisan migrate

• Model erweitern:
  • app/Models/Note.php: in $fillable eintragen
• Views erweitern:
  • Feld eventuell in index.blade.php eintragen
  • Feld in create.blade.php eintragen
  • Feld in edit.blade.php eintragen
  • Feld in show.blade.php eintragen
• NoteController anpassen:
  • function create() und edit() und show(): ... $fields = [ ... 'info' => ...];
  • function index():
    • Wenn ein Filter dazukommt: $fields = [ ... 'info' => ...]
    • Wenn bei einem gemeinsamen Suchfilter auch diese Spalte durchsucht werden soll:
      • ViewHelper::addConditionPattern($conditions, $parameters, 'title,body,info,', 'text');
    • Wenn ein Combobox als Filter dazukommt:
      • ViewHelper::addConditionComparism($conditions, $parameters, 'category_scope', 'category');
      • $optionsCategory = SProperty::optionsByScope('category', $fields['category'], 'all');
      • return view('note.index', [... optionsCategory ... ]);

Registerblatt-Seite

• Controller.edit()

$context = new ContextLaraKnife($request, null, $note);
$navigationTabInfo = ViewHelperLocal::getNavigationTabInfo('note-edit', 0, $note->id);
$rc = view('note.edit', [
  'context' => $context,
...
  'navTabsInfo' => $navigationTabInfo
]);

• view/note/edit.blade.php

@extends('layouts.backend')

@section('content')
    <form id="note-edit" action="/note-update/{{ $context->model->id }}" method="POST">
        @csrf
        <x-laraknife.panels.standard title="{{ __('Change of a Note') }}" fieldset="false">
            <x-laraknife.layout.nav-tabs :info="$navTabsInfo" fieldset="true">
                <x-laraknife.forms.combobox position="first" name="category_scope" label="Category" :options="$optionsCategory"
                    value="{{ $context->valueOf('category_scope') }}" width2="4" />
...
            </x-laraknife.layout.nav-tabs>
        </x-laraknife.panels.edit>
    </form>
@endsection

• ViewHelperLocal.php:

public static function getNavigationTabInfo(string $name, int $indexActive, 
  int $referenceId = 0): ?NavigationTabs
{
  $rc = null;
  switch ($name) {
     case 'note-edit':
        $rc = new NavigationTabs(["Properties;/note-edit/$referenceId",
            "Documents;/note-index_documents/$referenceId"
        ], $indexActive);
        break;
      default:
        break;
  }
  return $rc;
}

Email verschicken

• Anwendung

private function sendEmail(int $userId, Note $note){
  $user = User::find($userId);
  EmailHelper::sendMail('note.notification', $user->email, ['name' => $user->name, 'title' => $note->title, 'contents' => $note->body, 
   'from' => auth()->user()->name, 'link' => ViewHelper::buildLink("/note-edit/$note->id")]);
}

• app/Helpers/EmailHelper (Anpassung):

public static function sendMail(string $name, string $to, array $snippets)
  {
    switch ($name) {
    ...
    case 'note.notification':
      Mail::to($to)->send(new NoteNotification($snippets));
      break;
    default:
      break;
    }
}
