El tema es que cuando intento trabajar con dos entidade relacionadas me peta el "invento" con este error.
Código PHP:
An exception occurred while executing 'INSERT INTO Branch (book_id, parent_branch, phrase, creator_uid, level) VALUES (?, ?, ?, ?, ?)' with params [{}, null, "Write a blog post", 4, 1]:
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'parent_branch' cannot be null
