Activerecord-association: create new object (find class)

Question

I have an model with a relation, and I want to instantiate a new object of the relations type.

Example: A person has a company, and I have a person-obje

Answer 1

I'm currently using below solution. It's an actual solution, instead of the $has_one[1] hack I mentioned in the question. If there is a method in phpactiverecord I'm going to feel very silly exposing msyelf. But please, prove me silly so I don't need to use this solution :D

I am silly. Below functionality is implemented by the create_associationname call, as answered by @Bogdan_D

Two functions are added. You should probably add them in the \ActiveRecord\Model class. In my case there is a class between our classes and that model that contains extra functionality like this, so I put it there.

These are the 2 functions:

• public function findClassByAssociation($associationName)
  • Called with the name of the association you are looking for.
  • Checks three static vars (has_many,belongs_to and has_one) for the association
  • calls findClassFromArray if an association is found.
  • from the person/company example: $person->findClassByAssociation('company');
• private function findClassFromArray($associationName,$associationArray)
  • Just a worker-function that tries to match the name.

Source:

/**
 * Find the classname of an explicitly defined 
 * association (has_one, has_many, belongs_to). 
 * Unsure if this works for standard associations 
 * without specific mention of the class_name, but I suppose it doesn't!
 * @todo Check if works without an explicitly set 'class_name', if not: is this even possible (namespacing?)
 * @todo Support for 'through' associations.
 * @param String $associationName the association you want to find the class for
 * @return mixed String|false if an association is found, return the class name (with namespace!), else return false
 * @see findClassFromArray 
 */
public function findClassByAssociation($associationName){
    //$class = $this::$has_one[1]['class_name'];
    $that = get_called_class();
    if(isset($that::$has_many)){
        $cl = $this->findClassFromArray($associationName,$that::$has_many);
        if($cl){return $cl;}
    }
    if(isset($that::$belongs_to)){
        $cl = $this->findClassFromArray($associationName,$that::$belongs_to);
        if($cl){return $cl;}
    }
    if(isset($that::$has_one)){
        $cl = $this->findClassFromArray($associationName,$that::$has_one);
        if($cl){return $cl;}
    }
    return false;
}

/**
 * Find a class in a php-activerecord "association-array". It probably should have a specifically defined class name!
 * @todo check if works without explicitly set 'class_name', and if not find it like standard

private function findClassFromArray($associationName,$associationArray){
    if(is_array($associationArray)){
        foreach($associationArray as $association){
            if($association['0'] === $associationName){
                return $association['class_name'];
            }
        }

    return false;
