cakephp模型验证错误消息未显示在hasOne关联中 [英] cakephp Model validation error message not displaying in hasOne association
问题描述
我想以单一形式对association进行model验证.我有两个表users(父表)和user_details(子表).现在模型验证仅适用于users表.我也希望它适用于userDetails表.它们之间的关系是hasOne.
i want to do model validation with association in a single form. i have two tables users(parent table) and user_details(child table).now model validation is working for users table only.i want it for userDetails table also. relation between them is hasOne.
验证仅适用于用户表，因为我仅为用户表创建了newEntity.
validation working for only users table because i have created newEntity for users table only.

if ($this->Users->save($user)) {
$userDetail = $this->UserDetails->patchEntity($userDetail, $this->request->getData());
$userDetail->user_id = $user->id;
if ($this->UserDetails->save($userDetail)) {
$this->Flash->success(__('The user has been saved.'));
} else {
$this->Flash->error(__('The user could not be saved. Please, try again.'));

这是参考图片
在此图像中，所有字段均为必填 所有字段都来自用户表...仅地址字段来自user_details表.现在您可以看到显示名字字段的错误消息，但是不显示地址字段的错误消息.验证适用于地址字段，但不知道为什么出现错误消息没有显示.
in this image all fields are mandatory all fields are from users table...only address field is from user_details table.now you can see error message showing for first name field but error message not showing for address field.validation working for address field but don't know why error message is not displaying.
用户表中的名字和user_details表中的地址
first name from users table and address from user_details table
预先感谢
推荐答案
验证仅适用于用户表，因为我仅为用户表创建了newEntity.
validation working for only users table because i have created newEntity for users table only.
这与它无关.问题是您没有正确遵循命名约定.
That has nothing to do with it. The problem is that you are not following the naming conventions properly.
文件名必须与类名匹配，因此为UserDetailsTable.php，而不是UserDetails.php，UsersTable.php，不是usersTable.php，等等.
Filenames must match classnames, so it's UserDetailsTable.php, not UserDetails.php, UsersTable.php, not usersTable.php, etc.
并且hasOne关联的正确属性名称是关联名称的单数，强调的变体，因此对于UserDetails将是user_detail，因此相关表单控件的名称应为
And the correct property name for a hasOne association, is the singular, underscored variant of the association name, so for UserDetails that would be user_detail, consequently the name for the related form control should be user_detail.name.
