Symfony 3.2 CollectionType - forms

Question

Here's my problem. In my project, I have a one-to-many relationship between class FactureAchat and LigneFactureAchat, when I add a Facture the products are added in the Table ligne_facture_achat without having adding the foreign key of my Facture and an error is produced "Could not determine access type for property "LinesInvoicesPurchases". " the same problem with the display of a facture with its products. "An exception has been thrown during the rendering of a template (" Notice: Undefined index: factureachat ")."
