Seeding a grid field type

Created 7 years ago by dominique

I've made a module which has "types" to which you can assign multiple fields. For example an image or title. Seeding that isn't that difficult:

Fields migration for types:

        'title'       => [
            'type'   => 'anomaly.field_type.text',
            'locked' => 0,
        ],
        'image'       => [
            'type'   => 'anomaly.field_type.file',
            'locked' => 0, 
            'config' => [
                'image'   => true
            ]
        ],

Seeder:

    public function run()
    {
        $this->types->truncate();

        /* @var TypeModel $type */
        $type = $this->types
            ->create(
                [
                    'name'        => 'Example type',
                    'description' => 'Just an example type.',
                    'slug'        => 'no_text',
                    'layout'      => '<h1> Example </h1>'
                ]
            );

        $this->addTitleAndImageToType($type, false);

    }

    private function addTitleAndImageToType($type, $withTitle = true)
    {
        $stream = $type->getEntryStream();

        if ($withTitle) {
            $this->assignments->create(
                [
                    'stream' => $stream,
                    'field'  => $this->fields->findBySlugAndNamespace('title', 'portfolio')
                ]
            );
        }

        $this->assignments->create(
            [
                'stream' => $stream,
                'field'  => $this->fields->findBySlugAndNamespace('image', 'portfolio')
            ]
        );
    }

This works great but now I want to have some types which have grids assigned to them. How would I go about seeding a new grid field type?

Seeding a Grid relationship isn't a whole lot different than seeding any other relationship.

If your field is called grids then you would still do $entry->grids()->create($grid);

The $grid model is an instance of Anomaly\GridFieldType\Grid\GridModel which has a polymorphic relation that holds the actual row data.

Not tested but something like this:

$entry->grids()->create(
    new GridModel([
        'entry' => new GridsExampleEntryModel($attributes),
        'related' => $entry
    ])
);

In my fields migration I added this:

'column_grid'       => [
            'type'   => 'anomaly.field_type.grid',
            'locked' => 0, // used with seeded blocks
        ]

And in my seeder now looks like this:

    public function run()
    {
        $this->deleteStreamIfExsits('columns_blocks');

        $this->types->truncate();

        /* @var TypeModel $type */
        $type = $this->types
            ->create(
                [
                    'name'        => 'Columns',
                    'description' => 'A row of columns containing images, videos or text.',
                    'slug'        => 'columns',
                    'layout'      => 'TO DO',
                ]
            );

        $this->addGridToType($type);
    }

    public function addGridToType($type){
        $stream = $type->getEntryStream($type);

        $grid = $this->assignments->create(
            [
                'stream' => $stream,
                'field'  => $this->fields->findBySlugAndNamespace('column_grid', 'portfolio')
            ]
        );

        $grid->column_grid()->create(
            new GridModel([
                'entry' => new GridsExampleEntryModel($attributes),
                'related' => $entry
            ])
        );
    }

which gives me this error

Call to undefined method Illuminate\Database\Query\Builder::column_grid()

What am I doing wrong here?

Do you have eager loading or something setup somewhere? Looks like column_grid is being eager loaded as that instead of the relation method which is columnGrid.

I don't think I have. Changing column_grid to columnGrid gives me the same error.

Call to undefined method Illuminate\Database\Query\Builder::columnGrid()

Check out the actual model classes you're referencing - the relation methods will be listed. It's normal Eloquent. See if you can dig in and find what you need - I've put you on the right track 😊

Not quite sure what you mean. Do you mean I have to add the following to my TypeModel:

    use Anomaly\GridFieldType\Grid\GridModel;

    public function columnGrid()
    {
        return $this->hasMany(GridModel::class);
    }
