Add a model to the admin

Add admin directly to the model's existing modelRouter options:

export const userRouter = modelRouter("/users", User, {
  admin: {
    displayName: "Users",
    listFields: ["email", "name", "admin", "created"],
    searchFields: ["email", "name"],
    sortableFields: ["email", "name", "created"],
    filters: [{field: "admin", kind: "boolean", label: "Admin user"}],
  },
  permissions: {
    create: [Permissions.IsAdmin],
    delete: [Permissions.IsAdmin],
    list: [Permissions.IsAdmin],
    read: [Permissions.IsAdmin],
    update: [Permissions.IsAdmin],
  },
});

Register that router with TerrenoApp, then register AdminApp. The model appears in GET /admin/config and at /admin/User without a duplicate AdminApp.models entry.

If the same Mongoose model is mounted at two routePaths (different filters or list columns), /admin/config keeps name as the model name for the registered entry and suffixes the others with the route slug (for example Food-archived-foods) so each list is reachable.

Common fields:

• listFields: columns and fields exposed to admin CRUD.
• searchFields: string fields matched by the list search box (q) as a case-insensitive partial ($regex) query.
• sortableFields: the only columns with sorting enabled.
• filters: typed filter drawer controls.
• fieldsets: grouped form sections.
• readonlyFields / hiddenFields: display-only or omitted form fields.
• adminPermissions: optional admin-specific permission methods.
