[英]Sequelize: error of foreignKey constraint not reported when inserting new data?
I have table A one-to-many table B like below. 我有下表A的一对多表B。
A.associate = function(models) {
A.hasMany(models.B, {
foreignKey: 'a_id',
as: 'Bs'
});
}
When I insert record B, I use a random a_id which does not exist in A. Therefore, I expect it to report error of foreign key constraint. 当我插入记录B时,我使用A中不存在的随机a_id。因此,我希望它报告外键约束的错误。 But it doesn't report error, instead it adds B with a_id set to NULL.
但是它不会报告错误,而是将a_id设置为NULL的B添加。
Is there a setting to configure the model definition so that it can fail the operation and report error in such case? 是否存在用于配置模型定义的设置,以使其在这种情况下无法通过操作并报告错误?
Thanks. 谢谢。

Use "allowNull: false" in foreignKey. 在foreignKey中使用“ allowNull:false”。
