Configuración

1. Agregue las tres colecciones a su config/collections/index.ts
2. Ejecute rebase schema generate
3. Ejecute rebase db push
4. Reinicie el servidor de desarrollo

Ahora tiene un CMS de blog completamente funcional con:

• Gestión de autores con carga de avatares
• Etiquetado de categorías a través de relaciones de muchos a muchos
• Edición de contenido Markdown
• Flujo de trabajo Borrador → Revisión → Publicado
• Slugs de URL generados automáticamente
• Políticas RLS que limitan a los autores a sus propias publicaciones
• Historial de auditoría completo a través del historial de entidades

Consultando desde el SDK

Utilice el SDK del cliente para buscar artículos con sus relaciones:

// 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
}
