[英]Yii comparing attribute values of two different models
In my web application I need to compare the attribute values of two different models 在我的Web应用程序中,我需要比较两个不同模型的属性值
I want to compare the value of attribute named booked_quantity
of a model named BookVegetable
to the value of a attribute named offered_qty
of a model name ProducerOffer
. 我想比较属性命名的值
booked_quantity
一个名为模型BookVegetable
对指定的属性的值offered_qty
型号名称的ProducerOffer
。 What I want is the values of booked_quantity
should be lesser or equal to offered_qty but not greater. 我想要的是
booked_quantity
的值应该booked_quantity
或等于offer_qty,但不大于。 I tried searching it but no where I found for comparing two different model attribute values. 我尝试搜索它,但是没有找到用于比较两个不同模型属性值的地方。 How should I proceed ?
我应该如何进行? or should I compare it in the controller itself?
还是应该在控制器本身中进行比较? and generate flash error message?
并生成Flash错误消息? The code I tried but in vain
我尝试过的代码是徒劳的
public function compareBookedQuantity($booked_quantity,$params){
$count = BookVegetable::model()->findByAttributes(array('booked_quantity'=>$booked_quantity));
if ($count > $this->offered_qty){
$this->addError($booked_quantity,'Please enter a quantity lesser than offered quantity');
}
}
public function rules()
{
return array(
array('offered_qty','compareBookedQuantity'),
);
}
In my form I have values of both models. 在我的表单中,我具有两个模型的值。 How should I compare the attribute values ?
我应该如何比较属性值? please help The relations function in ProducerOffer model.
请帮助ProducerOffer模型中的关系函数。
public function relations()
{
return array( 'producerOfferBookVegetableRelation'=>array(self::BELONGS_TO, 'BookVegetable','id'),
);
}
First, if you want get booked_quantity, it will looks 首先,如果您想获得booked_quantity,它将看起来
$count = BookVegetable::model()->findByAttributes(array('booked_quantity'=>$booked_quantity))->booked_quantity;
Second, 第二,
public function compareBookedQuantity($booked_quantity,$params)
公共函数compareBookedQuantity($ booked_quantity,$ params)
Here $booked_quantity == 'offered_qty'. 这里$ booked_quantity =='offered_qty'。 It is the name of an attribute.
它是属性的名称。 But i didn't fully understand your question.
但是我不完全理解你的问题。 What model contains compareBookedQuantity function?
哪个模型包含compareBookedQuantity函数?
