Zielsetzung

Es soll eine minimale Web-Applikation mit den Werkzeugen Laravel und Laraknife erstellt werden: Eine Verwaltung von Notizen.

Name

Eine Verballhornung des Wortes "Tasks": Die schwäbische Aussprache spricht ein x am Ende.

Eigenschaften

  • Benutzerverwaltung: nur angemeldete Benutzer können Applikation nutzen
  • Rechteverwaltung mittels Rollen
  • Verwaltung von Notizen: Titel, Text, Kategorie, Status: offen, erledigt

Installation

  • als normaler Benutzer (nicht root):
SCRIPT=/tmp/CreateLaraProj.sh
wget "https://public.hamatoma.de/public/CreateLaraProj.sh" -O $SCRIPT
chmod +x $SCRIPT
PROJ=taskx
PASSW=topsecret
BASE=/home/ws/php
$SCRIPT $PROJ "$PASSW" "$BASE"
  • Am Ende wird dazu aufgefordert, das Script /tmp/IncludeLara.sh zu starten:
/tmp/IncludeLara.sh git $BASE/$PROJ

Mehrsprachigkeit (I18N)

larascripts/laraknife-tool.sh init-i18n
./Join
  • Die neuen Übersetzungen müssen in resources/lang/sources/taskx.de.json eingetragen werden.

Roles und SProperties füllen

larascripts/laraknife-tool.sh fill-db

Laraknife-Module anpassen

larascripts/laraknife-tool.sh adapt-modules

Homepage einrichten

  • Datei resources/views/home.blade.php
larascripts/laraknife-tool.sh create-home

Modul Notes erstellen

Tabellenbeschreibung erstellen

  • Konvention: Tabelle wird kleingeschrieben, im Plural
TABLE=notes
php artisan make:migration create_${TABLE}_table
  • Es wird die Datei database/migrations/2023_12_29_180821_create_notes_table.php erzeugt
  • Diese Datei anpassen:
        Schema::create('notes', function (Blueprint $table) {
            $table->id();
            $table->timestamps();
            $table->string('title');
            $table->text('body');
            // foreign key of sproperties.
            $table->integer('category_scope');
            // foreign key of sproperties.
            $table->integer('status_scope');
            $table->foreignId('user_id')->references('id')->on('users')->nullable();
        });

Modul erzeugen

php artisan migrate
./Lara create:module database/migrations/*_create_notes_table.php

Layout erstellen

  • Datei resources/views/layouts/taskx.blade.php erstellen:
larascripts/laraknife-tool.sh create-layout

Routing einrichten

  • In Datei routes/web.php einfügen:
SPropertyController::routes();
RoleController::routes();
UserController::routes();
NoteController::routes();
  • Es sind 4 Namen unterstrichen: mit Strg-Alt-I Klassen einbinden.

Starten, Registrieren, Login

  • Den Webserver starten:
./Build
php artisan serve

Controller und Views anpassen

Übersicht (index)

  • Datei app/Http/Controllers/NoteController.php
