Question

我有两个表，一个表“métier”和一个具有一对多连接的表“tâche”，一个“métier”有几个“tâche”。在我的表格“ajouter tâches”中，我有一个组合框，我从中选择与“tâche”相关的“métier”。 现在我只想用 libelle_metier 填充表 metier 中的组合，然后将我选择的 libelle_metier 的 ID 添加到表 tache 中，然后将其添加到 metier_id。有什么帮助吗？

Answer 1

如果我理解正确，您想通过 metier id 循环遍历 metiers 您需要更改

tache.blade.php

 ...
 <option value="{{ $metier->id }}">
 ...
