laravel插件 zofe/rapyd checkboxgroup bug修改

以官方Demo为例:

DataForm页面

去掉所有的复选框, 点击 Save 按钮

重新打开DataForm页面, 数据并没有改变, 这是bug

若至少保留其中一项, 则结果会改变

修改文件:

vendor/zofe/rapyd/src/DataForm/Field/Field.php

  修改前:

public function updateRelations() {
.....
case ‘Illuminate\Database\Eloquent\Relations\BelongsToMany‘:

                    $old_data = $this->relation->get()->modelKeys();
                    $new_data = explode($this->serialization_sep, $data);

                    $this->relation->detach($old_data);

                    if ($data==‘‘) {
                        continue;
                    }
.....

修改后:

public function updateRelations() {
case ‘Illuminate\Database\Eloquent\Relations\BelongsToMany‘:
.....
                    $old_data = $this->relation->get()->modelKeys();
                    //  $data 改成 $this->new_value
                    $new_data = explode($this->serialization_sep, $this->new_value);

                    $this->relation->detach($old_data);

                    //判断条件修改
                    if (empty($this->new_value)) {
                        break;
                    }
                    ......
