Question

我有一个PostgreSQL数据库，表名和字段名都有空格。我无法控制这个数据库结构。问题不在于表名，而是带有脚手架CRUD代码的字段名。这是一个例子：

CREATE TABLE "public"."MILESTONES 4 FORM TABLE" (
"Estimate ID" varchar(250) NOT NULL DEFAULT 'None'::character varying COLLATE "default",
"MS 4 Name" varchar(100) NOT NULL COLLATE "default",
"MS 4 Begin" varchar(50) COLLATE "default",
"MS 4 End" varchar(50) COLLATE "default",
"MS 4 Weight" float4 DEFAULT 0.0,
"MS 4 % Oct" float4 DEFAULT 0.0,
"MS 4 % Nov" float4 DEFAULT 0.0,
....the other months here... deleted for brevity
"MS 4 % Sep" float4 DEFAULT 0.0,
"Change Control Choice" varchar(50) COLLATE "default",
"CV% MS Oct Cum" varchar(50) COLLATE "default",
"SV% MS Oct Cum" varchar(50) COLLATE "default",
"CV% MS NOV Cum" varchar(50) COLLATE "default",
"SV% MS NOV Cum" varchar(50) COLLATE "default",
....the other months here... deleted for brevity
"CV% MS Sep Cum" varchar(50) COLLATE "default",
"SV% MS Sep Cum" varchar(50) COLLATE "default"
);

Gii为模型生成了以下内容（我必须注释掉@property声明，因为PHPStorm将它们标记为错误）：

<?php

namespace app\models;

use Yii;

/**
 * This is the model class for table "MILESTONES 4 FORM TABLE".
 *
//* @property string $Estimate ID
//* @property string $MS 4 Name
//* @property string $MS 4 Begin
//* @property string $MS 4 End
//* @property double $MS 4 Weight
//* @property double $MS 4 % Oct
//* @property double $MS 4 % Nov
...deleted for brevity
//* @property double $MS 4 % Sep
//* @property string $Change Control Choice
//* @property string $CV% MS Oct Cum
//* @property string $SV% MS Oct Cum
...deleted for brevity...
//* @property string $CV% MS Sep Cum
//* @property string $SV% MS Sep Cum
 */
class Milestone4AR extends \yii\db\ActiveRecord
{
    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return 'MILESTONES 4 FORM TABLE';
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['Estimate ID', 'MS 4 Name'], 'required'],
            [['MS 4 Weight', 'MS 4 % Oct', 'MS 4 % Nov', 'MS 4 % Dec', 'MS 4 % Jan', 'MS 4 % Feb', 'MS 4 % Mar', 'MS 4 % Apr', 'MS 4 % May', 'MS 4 % Jun', 'MS 4 % Jul', 'MS 4 % Aug', 'MS 4 % Sep'], 'number'],
            [['Estimate ID'], 'string', 'max' => 250],
            [['MS 4 Name'], 'string', 'max' => 100],
            [['MS 4 Begin', 'MS 4 End', 'Change Control Choice', 'CV% MS Oct Cum', 'SV% MS Oct Cum', 'CV% MS NOV Cum', 'SV% MS NOV Cum', 'CV% MS Dec Cum', 'SV% MS Dec Cum', 'CV% MS Jan Cum', 'SV% MS Jan Cum', 'CV% MS Feb Cum', 'SV% MS Feb Cum', 'CV% MS Mar Cum', 'SV% MS Mar Cum', 'CV% MS Apr Cum', 'SV% MS Apr Cum', 'CV% MS May Cum', 'SV% MS May Cum', 'CV% MS Jun Cum', 'SV% MS Jun Cum', 'CV% MS Jul Cum', 'SV% MS Jul Cum', 'CV% MS Aug Cum', 'SV% MS Aug Cum', 'CV% MS Sep Cum', 'SV% MS Sep Cum'], 'string', 'max' => 50],
        ];
    }

    /**
     * @inheritdoc
     */
    public function attributeLabels()
    {
        return [
            'Estimate ID' => 'Estimate  ID',
            'MS 4 Name' => 'Ms 4  Name',
            'MS 4 Begin' => 'Ms 4  Begin',
            'MS 4 End' => 'Ms 4  End',
            'MS 4 Weight' => 'Ms 4  Weight',
            'MS 4 % Oct' => 'Ms 4 %  Oct',
            'MS 4 % Nov' => 'Ms 4 %  Nov',
...deleted for brevity...
            'MS 4 % Aug' => 'Ms 4 %  Aug',
            'MS 4 % Sep' => 'Ms 4 %  Sep',
            'Change Control Choice' => 'Change  Control  Choice',
            'CV% MS Oct Cum' => 'Cv%  Ms  Oct  Cum',
            'SV% MS Oct Cum' => 'Sv%  Ms  Oct  Cum',
...deleted for brevity...
            'CV% MS Sep Cum' => 'Cv%  Ms  Sep  Cum',
            'SV% MS Sep Cum' => 'Sv%  Ms  Sep  Cum',
        ];
    }
}

然后我使用Gii从模型生成CRUD代码。您可以在$ query-＆gt; andFilterWhere部分中看到问题的示例。例如，...和.FilterWhere（[＆＃39;喜欢＆＃39;，＆＃39; MS 4名称＆＃39;，$ this-＆gt; MS 4名称]）将无法解析。

我做错了什么，我该如何解决？

这不是生产代码（还），所以我可以很容易地吹走我已经完成的工作，但我不能改变原来的数据库表结构（男孩，我希望我能做什么）！我真的不喜欢遗留代码）。我有超过100个表使用相同的命名约定，因此需要一个可以应用于所有表的修复。

    {
        return [
            [['Estimate ID', 'MS 4 Name', 'MS 4 Begin', 'MS 4 End', 'Change Control Choice', 'CV% MS Oct Cum', 'SV% MS Oct Cum', 'CV% MS NOV Cum', 'SV% MS NOV Cum', 'CV% MS Dec Cum', 'SV% MS Dec Cum', 'CV% MS Jan Cum', 'SV% MS Jan Cum', 'CV% MS Feb Cum', 'SV% MS Feb Cum', 'CV% MS Mar Cum', 'SV% MS Mar Cum', 'CV% MS Apr Cum', 'SV% MS Apr Cum', 'CV% MS May Cum', 'SV% MS May Cum', 'CV% MS Jun Cum', 'SV% MS Jun Cum', 'CV% MS Jul Cum', 'SV% MS Jul Cum', 'CV% MS Aug Cum', 'SV% MS Aug Cum', 'CV% MS Sep Cum', 'SV% MS Sep Cum'], 'safe'],

            return $dataProvider;
        }

        // grid filtering conditions

Answer 1

在您的情况下，您不能使用速记属性，因为它的PHP属性命名规则存在冲突。

您可以使用解决方案。

你可以这样调用属性：

$model->getAttribute('MS 4 Name')

或者您可以在模型中准备别名属性，如：

public $ms4name;

然后在afterFind()填写它们，如：

public function afterFind()
{
    $this->ms4name = $this->getAttribute('MS 4 Name');
    parent::afterFind();
}

所以从这一点开始你可以使用

$model->ms4name
