v5:activerecord:hasmany

# hasMany

This method is deprecated, use classhasmany / tablehasmany / tablekeyhasmany instead.

##### Syntax

    void hasMany(
      string $relation,
      optional string $foreignKey = ''
    )

## Description

The deprecated method was used to define a one-to-many relationship

## Usage

In this example we have 2 tables, persons (parent table) and children (child table) linked by persons.id = children.person_id. The variable $person→children is an array that holds the children.

    class person extends ADOdb_Active_Record{}

    $person = new person();
    $person->HasMany('children','person_id');
    $person->Load("id=1");
    foreach($person->children as $c) {
        echo " $c->name_first ";
        $c->name_first .= ' K.';
        $c->Save();  ## each child record must be saved individually
    }
