Hello All,

I am newbie to yii and trying to learning it.

I am little bit confused to use relations,

in my application i have 3 tables

users :

id

username

user_profiles:

id

user_id (FK users(id))

first_name

last_name

Album:

id

user_id (FK users(id))

album_name

album_code

In grid view of "Album" i am going to display

user_name , album_code, album_name

in this case how to use relation. please explain me

Thank you

In ur UserProfileModel:

public function getUser()


{


    return $this->hasOne(User::className(), ['id' => 'user_id']);


}

In ur AlbumModel:

public function getUser()


{


    return $this->hasOne(User::className(), ['id' => 'user_id']);


}

In your albumgrid for username

[


            'user.user_name',


],





**Rules for relation: u should use same fkname as pkname.


**Rules for db design: do not use "_" in field name.

Ask if u have ny doubt
