小编Kru*_*nal的帖子

请在此代码中解释,

当我调用另一个方法时,如何再次调用ngOnInit()

 ngOnInit(): void {
      this.route.params.subscribe((params: Params) => {
        this.model=this.userData;
  });      
 }         

 update() {
        this.loading = true;
        this.userService.update(this.model)
            .subscribe(
                data => {
                    alert ('Update successful');
                },
                error => {
                    alert  ('Not updated');
                    this.loading = false;
                });
                this.user_data();
    }

授予服务帐户的权限为“所有者”和“ bigquery admin”。

$bigQuery = new BigQueryClient([
            'projectId' => 'project-xxx',
        ]);

      $query = "SELECT * FROM `project-xxxx.analytics_xxx.events_xxx` where event_name='first_open' LIMIT 100";

        $jobConfig = $bigQuery->query($query);
        $queryResults = $bigQuery->runQuery($jobConfig);
        print_r($queryResults);

当我尝试执行以上代码时，其显示以下错误：

{ "error": 
{ "errors": [ { "domain": "global", "reason": "accessDenied", 
  "message": "Access Denied: Project project-xxxx: The user 
  projectbigquery@project-xxxx.iam.gserviceaccount.com does not have 
  bigquery.jobs.create permission in project project-xxxx." } ],
}}

这是我的代码,在姓氏中,我使用了ngModel,因此它使用双向数据绑定,但在单选按钮中我是如何使用ngModel进行双向数据绑定的.

   <div class="form-group" [ngClass]="{ 'has-error': f.submitted && !lastname.valid }">
                    <label for="lastname">Last Name</label>
                    <input type="text" class="form-control" name="last_name" [(ngModel)]="employee.last_name" #lastname="ngModel" required />
                    <div *ngIf="f.submitted && !lastname.valid" class="help-block">Last Name is required</div>
                </div>
                <div class="form-group">
                    <label>Gender:</label> &nbsp;
                    <label class="radio-inline">
                    <input type="radio" name="optradio" [checked]="employee.gender == 'Male'" >Male
                </label>
                    <label class="radio-inline">
                     <input type="radio" name="optradio" [checked]="employee.gender == 'Female'" >Female
                </label>
                </div>

我想在更新新图像时删除存储的图像

public function update($id)
    {
        $users = AdminLogin::find($id);

        if(Input::hasFile('image_file'))
        {
            $file = Input::file('image_file');
            $name = time() . '-' . $file->getClientOriginalName();
            $file = $file->move(('uploads/images'), $name);
            $users->image_file= $name;
        }
        $users->save();
        return response()->json($users);
    }
