Laravel Eloquent polymorphic one-to-one?

Question

I'm trying to setup a polymorphic one-to-one relationship (the polymorphic equivalent of has_one and belongs_to).I've got an `Address` model, and there are several other models that I want to have one address. However, I'm confused by the wording of the docs. I've seen the `morphMany` method, but my question is: should I use `morphMany` even though I only want it to have one address, or is there something like a `morphOne` method I should be using? EDIT: My `Address` model has these fields, just to help visualize: ``` Schema::create('addresses', function ($table) { $table->increments('id'); $table->string('street'); $table->string('street_more')->nullable(); $table->string('city'); $table->string('state')->nullable(); $table->string('country'); $table->string('postal_code'); $table->integer('addressable_id'); $table->string('addressable_type'); }); ```

Accepted Answer

Yes, there is a morphOne method and I think is the one you should use in this case: https://github.com/laravel/framework/blob/5.2/src/Illuminate/Database/Eloquent/Model.php#L811 .

Also you can use

```
$table->morphs('addressable');
```

instead of

```
$table->integer('addressable_id');
$table->string('addressable_type');
```

I've used morphOne in a custom package for L4 and works pretty well.
