Load all relationships for a model

Question

Usually to eager load a relationship I would do something like this:

Model::with(\'foo\', \'bar\', \'baz\')...

A solution might be to set

Answer 1

There's no way to know what all the relations are without specifying them yourself. How the other answers posted are good, but I wanted to add a few things.

Base Model

I kind of have the feeling that you want to do this in multiple models, so at first I'd create a BaseModel if you haven't already.

class BaseModel extends Eloquent {
    public $allRelations = array();
}

"Config" array

Instead of hard coding the relationships into a method I suggest you use a member variable. As you can see above I already added $allRelations. Be aware that you can't name it $relations since Laravel already uses that internally.

Override with()

Since you wanted with(*) you can do that too. Add this to the BaseModel

public static function with($relations){
    $instance = new static;
    if($relations == '*'){
        $relations = $instance->allRelations;
    }
    else if(is_string($relations)){
        $relations = func_get_args();
    }
    return $instance->newQuery()->with($relations);
}

(By the way, some parts of this function come from the original Model class)

Usage

class MyModel extends BaseModel {
    public $allRelations = array('foo', 'bar');
}

MyModel::with('*')->get();
