Table Resource

Table resources map custom DB tables through WordPressTableRepository/WpdbAdapter.

Deny-by-default (v0.3.0)​

Table resources reject every action — including list and get — until a policy() is configured. This is the most important behavioral change in v0.3.0 for table-backed endpoints. Use a ResourcePolicy preset or supply an explicit permissions array.

Minimal example​

use BetterRoute\Resource\Resource;
use BetterRoute\Resource\ResourcePolicy;

Resource::make('raw-articles')
    ->restNamespace('better-route/v1')
    ->sourceTable('ai_raw_articles', 'id')
    ->allow(['list', 'get', 'create', 'update', 'delete'])
    ->fields(['id', 'source', 'title', 'lang', 'published', 'created_at', 'updated_at'])
    ->filters(['source', 'lang', 'published'])
    ->filterSchema([
        'source' => 'string',
        'lang' => 'string',
        'published' => 'bool',
    ])
    ->sort(['created_at', 'id'])
    ->maxPerPage(100)
    ->maxOffset(5000)
    ->policy(ResourcePolicy::adminOnly('manage_options'))
    ->register();

SQL safety model​

WpdbAdapter enforces:

  • identifier validation for table/field/sort names
  • prepared statements for values
  • prefixed table resolution via $wpdb->prefix
  • (v0.3.0) cross-database table names (containing .) are rejected
  • (v0.3.0) structured (array/object) write payloads are rejected at the storage boundary

Scenario: ingestion rows with typed filters​

  • Declare source_id as int, published as bool
  • Requests like ?source_id=12&published=true are type-coerced before repository call

Common mistakes​

  • Missing fields() (required for table resources)
  • Using invalid SQL identifiers in field names
  • Assuming unknown query params are ignored
  • (v0.3.0) skipping policy() — every action returns 403 without an explicit policy
  • (v0.3.0) attempting to reference a foreign database via other_db.table — rejected at the adapter layer

Validation checklist​

  • list queries use LIMIT/OFFSET with prepared args
  • invalid identifiers fail early
  • create/update payload keys outside allowlist return 400 validation_failed
