Question

我的控制器：

public function actionCreate()
    {
            $model = new CreateBookings();

            if ($model->load(Yii::$app->request->post())) 
            {
                $imageName = $model->primary_name;
                $model->file = UploadedFile::getInstance($model, 'file');
                $model->file->saveAs('uploads/'.$imageName.'.'.$model->file->extension);
                $model->id_image = 'uploads/'.$imageName.'.'.$model->file->extension;
                $model->save();

                return $this->redirect(['view', 'id' => $model->id]);
            } else 
            {
                return $this->render('create', [
                    'model' => $model,
                ]);
            }

    }

在提交表单时出现此错误，不知道它有什么问题.. 试过$model->save(false); ..但不能正常工作

尝试使用public function actionCreate() { $model = new CreateBookings(); if ($model->load(Yii::$app->request->post())) { $imageName = $model->primary_name; $model->file = UploadedFile::getInstance($model, 'file'); $model->file->saveAs('uploads/'.$imageName.'.'.$model->file->extension); $model->id_image = 'uploads/'.$imageName.'.'.$model->file->extension; if($model->save()) { $lastInsertID = $model->getPrimaryKey(); return $this->redirect(['view', 'id' => $lastInsertID]); } else { // print_r($model->getErrors()); => check whether any validation errors are there } } else { return $this->render('create', [ 'model' => $model, ]); } }方法：

awk '{a[$1]+=$2; c[$1]++} END{for (i in a) printf "%d%s%.2f\n", i, OFS, a[i]/c[i]}' file
