在 yii2 中实现多选下拉菜单时出现完整性约束违规错误

问题描述 投票：0回答：2

我正在尝试使用“cornernote/yii2-linkall”和“kartik-v/yii2-widget-select2”实现多选下拉菜单。我已经遵循了本指南，它对于单个多选下拉菜单很有用，所以现在我尝试以单一形式实现两个多选下拉菜单，但我被困住了。 当我重复执行更新功能时，它会给出违反完整性约束的错误。 

Integrity constraint violation – yii\db\IntegrityException
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '34-1' for key 'PRIMARY'
The SQL being executed was: INSERT INTO `supplier_to_industry` (`supplier_id`, `industry_id`) VALUES (34, 1)

Error Info: Array

    [0] => 23000

数据库表如下所示： 部分（ID，名称） 行业（ID，名称）

supplier_to_part(supplier_id,part_id) 供应商_行业（供应商_id，行业_id）

主表是：-供应商（id，......）

afterSave()有什么问题吗？有什么帮助吗

在所需的表单字段上使用 $model 变量调用模型名称。例如：

 <?= $form->field($model->industry,'industry_ids')->widget(Select2::className(),['model' => $model->industry, ...

问题出在 foreach 上。

而不是 

              foreach ($this->part_ids  as $part_name ){ 
                foreach ($this->industry_ids as $industry_name ){ 
                      $part = Part::getPartByName($part_name);
                     $industry = Industry::getIndustryByName($industry_name);
                   if ($part ||$industry ) {
                    $parts[] = $part;
                    $industries[] = $industry;
                   }
               }
          }

需要使用：

       foreach ($this->production_scope as $part_name ){ 
                $part = Part::getPartByName($part_name);
                if ($part) {
                    $parts[] = $part;
                }
            }
        foreach ($this->target_industry as $industry_name ){ 
                $industry = Industry::getIndustryByName($industry_name);
                if ($industry) {
                    $industries[] = $industry;
                }
            }
