 - A multiplicidade da relação: especificada chamando tanto o método [[yii\db\ActiveRecord::hasMany()|hasMany()]] quanto o método [[yii\db\ActiveRecord::hasOne()|hasOne()]]. No exemplo acima você pode facilmente ler nas declarações de relação que um `customer` tem vários `orders` enquanto uma `order` só tem um `customer`.

Os valores do array são as colunas da tabela primária (representada pela classe Active Record que você declarou as relações), enquanto as chaves do array são as colunas da tabela relacionada.
 
 Uma regra fácil de lembrar é, como você pode ver no exemplo acima, você escreve a coluna que pertence ao Active Record relacionado diretamente ao lado dele. Você pode ver que `customer_id` é uma propriedade de `Order` e `id` é uma propriedade de  `Customer`.
