后台获取数据关联知识点
关联关系图
watchRecordModel 课程观看记录表： 课程观看记录Model：
courseModel 课程表 课程Model
课程——期——章节关联表 期——章节Model：
课时表 课时Model：
以下是获取后台的code
/**
* 获取个人进度详情信息(Vip)
*
*/
public function getVipCourses(){
$page = post('page',1);
// trace_log(111);exit;
$userId = $this->formatParam();
if(!empty($userId)){
$courseIds = WatchRecordModel::where('user_id',$userId)->distinct()->lists('course_id');
// trace_log($courseIds);exit;
if(!empty($courseIds)){
$courses = Course::where('type_id',2)->where('status',2)->whereIn('id',$courseIds)
->with('period.units.lessons.watchrecord')
->get()
->toArray();
// trace_log($courses);exit;
return $courses;
}
}
return '0';
}
