To solve your problem, you need to set ids in the One2Many like this .

@api.one
def get_article_list(self):
    art = self.env["facturation.articleouvrage"].search([]).ids
    self.id_articleouvrage = art
    print self.id_articleouvrageer`

In your field One2many you specify an attribute relation. But it's only for Many2mnay field.
