显示CGridView中另一个模型的属性 [英] Showing attributes of another model in CGridView
问题描述
In Yii I am doing multimodel.My database is something like this
在Yii中,我在做多模式。 ++
id
名称
+++++会员++++++
id
group_id
名字
姓氏
membersince
+++++ Group ++++++
id
name
+++++ Member ++++++
id
group_id
firstname
lastname
membersince
在组控制器中,我想显示成员的属性。一切正常但是当我使用菜单中的管理选项时,它将显示两个模型的属性,但是显示在两个不同的网格视图中。我想在单个网格视图中显示两个模型属性。
成员控制器的代码就像这样
In Group controller I want to show Member's attributes.Everything is working fine but when I am using manage option from the menu it is showing the attributes for both models but in two different grid-view.I want to show both models attributes in a single grid-view. The code for Member controller is like this
public function actionAdmin()
{
$model=new Group('search');
$model->unsetAttributes(); // clear any default values
if(isset($_GET['Group']))
{
$model->attributes=$_GET['Group'];
}
$member=new Member('search');
$member->unsetAttributes(); // clear any default values
if(isset($_GET['Member']))
{
$model->attributes=$_GET['Member'];
}
$this->render('admin',array(
'model'=>$model,
'member'=>$member,
));
}
用于组管理代码中的视图就像这样
for View in Group admin code is like this
<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'member-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'columns'=>array(
'id',
'name',
array(
'class'=>'CButtonColumn',
),
),
));
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'member-grid',
'dataProvider'=>$member->search(),
'filter'=>$member,
'columns'=>array(
'firstname',
'lastname',
array(
'class'=>'CButtonColumn',
),
),
));
这里我使用了CGridView两次来显示两个属性的模型。那么有人可以告诉我如何在单个
CGridView中显示模型。任何帮助和建议都会非常有价值。

模型中的关系:
组模型
Here I have used CGridView for two times to show models for both attributes. So can someone tell me how to show models in a single CGridView.Any help and suggestions will be highly appriciable. [Updated] Relations in Models: Group Model
public function relations()
{
// NOTE: you may need to adjust the relation name and the related
// class name for the relations automatically generated below.
return array(
'member' => array(self::HAS_MANY, 'Member', 'group_id'),
);
}
会员模式:
Member Model:
public function relations()
{
// NOTE: you may need to adjust the relation name and the related
// class name for the relations automatically generated below.
return array(
'group' => array(self::BELONGS_TO, 'Group', 'group_id'),
);
}
推荐答案
访问相关的简单方法yii中的模型字段是使用像这样的元素:
$ model-> relatedModel->字段
- 如果存在模型之间的 has_one 或 belongs_to 关系。
因此,你可以使用你的情况来访问成员的组名称
$ memberModel-> group-> name
但是当你需要访问相关的模型字段对于 has_many 或 many_many 关系类型,您需要执行如下操作:像
$ model-> relatedModel [ arrayIndex] - > field
这是因为在这种情况下有许多相关模型,而yii会自动给你数组中的相关模型。 b $ b在你的情况下,一个组有许多成员并访问gro的特定成员(比如说,第一个成员,即 arrayIndex = 0 )你可以使用 $ groupModel->成员[0] - > firstname
现在要回答你确切的问题,首先,您不需要声明或初始化或传递$ member模型。所以你的控制器动作可以是
A simple way to access related model fields in yii is to use something like this
$model->relatedModel->field
-- this can be used if there is a has_one, or belongs_to relation between the models.
So in your case, you can access the group name of a member using the code
$memberModel->group->name
But when you need to access related model fields for has_many, or many_many relation types, you will need to do something like
$model->relatedModel[arrayIndex]->field
This is because there are many related models in this case, and yii automatically gives you the related model in an array.
In your case a group has many members and to access a particular member(say the first member, i.e arrayIndex = 0) of a group you can use $groupModel->members[0]->firstname
Now to coming to your exact question, first of all, you do not need to declare or initialize or pass the $member model. So your controller action can be
public function actionAdmin(){
$model=new Group('search');
$model->unsetAttributes(); // clear any default values
if(isset($_GET['Group'])){
$model->attributes=$_GET['Group'];
}
$this->render('admin',array(
'model'=>$model
)
);
}
显然,在您的视图中,您不需要两个网格视图
Then obviously in your view you don't need the two grid-views
<?php
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'member-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'columns'=>array(
'id',
'name',
array( // this is for your related group members of the current group
'name'=>'members.firstname', // this will access the attributeLabel from the member model class, and assign it to your column header
'value'=>'$data->members[0]->firstname', // this will access the current group's 1st member and give out the firstname of that member
'type'=>'raw' // this tells that the value type is raw and no formatting is to be applied to it
),
array(
'class'=>'CButtonColumn',
),
),
));
希望这有助于您。
