禁用规则模型 yii 上的字段 [英] disable field on rules model yii
问题描述
我正在尝试禁用更新规则模型上的字段,但出现错误.
i am trying to disable a field on update rules models but i am having error.
我尝试:
array('date', 'constraint', 'readOnly'=>true, 'on'=>'update'),
但是我遇到了这个错误:
but i am having this error:
include(constraint.php): 无法打开流:没有那个文件或目录"
"include(constraint.php): failed to open stream: No such file or directory"
我可以使用 htmloptions 从视图中禁用,但我需要从模型中禁用,因为在更新时我需要禁用 5 个以上的字段.
I can disable from view using htmloptions but i need do it from model because on update i need to disable more than 5 fields.
我怎么能这样做?
提前谢谢
推荐答案
您使用不存在的验证器声明规则,因此出现错误是正常的:
You are declaring a rule with a validator that doesn't exist, so it's normal that you have an error:
array('date', 'constraint', 'readOnly'=>true, 'on'=>'update'),
这一行正在执行以下操作:在 update
场景中的 date
字段上应用验证器 constraint
,参数为 readOnly
设置为 true
.
This line is doing the following: apply the validator constraint
on the date
field on update
scenario with param readOnly
set to true
.
验证器 constraint
不存在,在 Yii 中有一个内置的功能,所以如果你没有创建它,那么它就不存在!
The validator constraint
doesn't exists has a built in functonnality in Yii so if you havn't created it then it doesn't exist!
文档:
在您的表单中,您可以执行以下操作:
In your form you could do something like:
<?php
echo $form->textField(
$model,
'email',
array('readonly'=>($model->scenario == 'update')? true : false)
);
?>
如您所见,只读值将取决于场景.
As you can see the readonly value will depend on the scenario.
