Models and Mapper

When we synchronize all the data on database the mapper link to the model are call. This mapper car provide the extract of field you would like one the database. For example you want to externalize the title and the slug on the database you have to change the migration generated and the mapper.

    class TerritoryMapper extends ContentfulMapper
    {
        /**
         * {@inheritdoc}
         */
        protected function map(array $entry, string $locale): array
        {
            $payload = $this->mapPayload($entry, $locale);
    
            return [
                'slug' => isset($payload['slug']) ? Caster::string($payload['slug']) : '',
                'title' => isset($payload['title']) ? Caster::string($payload['title']) : '',
            ];
        }
    }

    class Territory extends ContentfulModel
    {
        /**
         * {@inheritdoc}
         */
        protected $table = 'territories';
    
        /**
         * {@inheritdoc}
         */
        protected $fillable = [
            'slug',
            'title',
        ];
    
        /**
         * Picture attribute accessor.
         *
         * @return \Distilleries\Contentful\Models\Asset|null
         */
        public function getPictureAttribute(): ?Asset
        {
            return isset($this->payload['picture']) ? $this->contentfulAsset($this->payload['picture']) : null;
        }
    }

All the model generated have a getters for all the payload fields. If you want to externalize the field on database.

Command-line tools

To make model and mapper from contentful

• php artisan contentful:generate-models

ℹ️ Models are generated on app_path('Models'); and the mappers are generated on app_path('Models/Mappers');

To make migration from contentful model

• php artisan contentful:generate-migrations

To launch the synchronisation you can use this command line

• php artisan contentful:sync-data {--preview}

• php artisan contentful:sync-flatten {--preview}

ℹ️ --preview is optional and use if you want to flatten the preview database.

Command	Explain
sync-data	Get all the entries from contentful and put in the flatten database
sync-flatten	Get all the entries from data table to explode on all the other types

Webhook

To flatten the preview or the regular database you need to set the webhook on Contentful

Create a controller and use the trait:

use \Distilleries\Contentful\Http\Controllers\WebhookTrait;

Make the route callable in post:

    $router->post('/webhook/live', 'WebhookController@live');
    $router->post('/webhook/preview', 'WebhookController@preview');

• Live method is called to save on live mode

• Preview method is called to save the preview data

To display the site with preview database you have to use UsePreview middleware.

    $router->group(['prefix' => 'preview', 'middleware' => 'use_preview'], function () use ($router) {
        //
    });

Add your middleware:

    'use_preview' => Distilleries\Contentful\Http\Middleware\UsePreview::class,
