Artikel

Einrichtung

1. Fügen Sie alle drei Sammlungen zu Ihrer config/collections/index.ts hinzu
2. Run rebase schema generate
3. Run rebase db push
4. Starten Sie den Entwicklungs-Server neu

Sie verfügen nun über ein voll funktionsfähiges Blog-CMS mit:

• Autorenverwaltung mit Avatar-Uploads
• Kategorisierung über Many-to-Many-Beziehungen
• Markdown-Inhaltsbearbeitung
• Workflow: Entwurf → Überprüfung → Veröffentlicht
• Automatisch generierte URL-Slugs
• RLS-Richtlinien, die Autoren auf ihre eigenen Beiträge beschränken
• Vollständiger Prüfpfad über die Entitätshistorie

Abfragen aus dem SDK

Verwenden Sie das Client-SDK, um Artikel mit ihren Beziehungen abzurufen:

// The row shape you expect back — without it every field arrives as `unknown`.
type Article = {
    title: string;
    status: string;
    published_at?: string | null;
    author_id: string;
    author?: { name: string };
    categories?: { name: string }[];
};

// Fetch published articles with author and categories included
const { data: articles } = await client.data
    .collection<Article>("articles")
    .where("status", "==", "published")
    .include("author", "categories")
    .orderBy("published_at", "desc")
    .limit(10)
    .find();

// Rows come back flat — there is no `values` wrapper on the SDK.
for (const article of articles) {
    console.log(article.title);
    console.log(article.author?.name);    // Hydrated relation
    console.log(article.author_id);       // Scalar FK
    console.log(article.categories);      // Array of related entities
}
