A Laravel package to extend any model with meta fields.

README

If you're constantly updating migration scripts with column changes for your models. You might find adding a morphed relationship to store all this as Meta usual.

Installation

composer require developerswarehouse/meta

How it works

The concept here is to store only essential data in the models table (users): name, emails, password. For additional data, you should store these in the Meta table, as optional properties e.g. gender, height, nationality.

Usage

On your Laravel models, add the trait for meta.

use DevelopersWarehouse\Meta;

class User extends Authenticatable
{
    use Meta;
}

To populate a models meta, use the Eloquent methods for updating a one-to-many relationship:

Example HMTL Form

<form action="" method="POST">
    {{ csrf_field() }}
    <input type="text" name="meta[height]" />
    <input type="text" name="meta[telephone]" />
    <input type="radio" name="meta[gender]" value="male" />
    <input type="radio" name="meta[gender]" value="female" />
    <button>Save</button>
</form>

Controller method

public function update(Request $request, User $user) {

    if ($request->has("meta.*")) {
        foreach($request->input("meta.*") as $key => $value) {
            if ($value) {
                $user->meta()->updateOrCreate(['key' => $key],['value' => $value]);
            } else {
                $user->meta()->where("key", $key)->delete();
            }
        }
    }

}

To display the meta property for a model, you can use the relation attribute meta.

$user->meta;
// if you knwo the meta key, say height
$user->metaValueByKey('height'); // returns collection()
// or if you know the meta key
$user->metaHeight; // 5'10
$user->metaGender; // female
$user->metaSomething; // null

Further Developments

I will be looking to extend the functionality to include better value lookups an might try to include the dot notation for array support.
