Question

我有一个应用程序，我正在尝试添加第二个模块。

基本上我正在克隆已经在使用我的数据库的现有模块。除了不同的表名和不同的控制器/类/型号名称之外，所有代码都与原始/工作模块完全相同。

我有3个与新模块相关的新表，就像旧模块investments，investment_categories和investment_vendors一样。
每次我尝试使用我的新模块时，它都希望将供应商和类别名称值上传到investments表，然后将其上传到相应的investment_categories和investment_vendor表。

我不相信问题出在我的新模块代码上，而是作曲家内的其他地方我不希望我需要运行composer dump-autoload，因为我总是编辑我的模块而不运行它（但这是我第一次更新一个查询/写入另一个表）。

我需要运行其他东西才能让它发挥作用吗？

我在日志中看到的以下错误是：

[2018-01-24 21:13:21] production.ERROR：PDOException：SQLSTATE [42S22]：找不到列：1054 / var / www // vendor /中的'字段列表'中的未知列'category_name' laravel /框架/ SRC /照亮/数据库/ Connection.php：390

控制器文件：

<?php

namespace MC\Modules\Investments\Controllers;

use MC\Http\Controllers\Controller;
use MC\Modules\Investments\Models\Investment;
use MC\Modules\Investments\Models\InvestmentCategory;
use MC\Modules\Investments\Models\InvestmentVendor;

class InvestmentController extends Controller
{
    use ReturnUrl;

    public function index()
    {
        $this->setReturnUrl();

        $investments = Investment::defaultQuery()
            ->keywords(request('search'))
            ->categoryId(request('category'))
            ->vendorId(request('vendor'))
            ->sortable(['investment_date' => 'desc'])
            ->paginate(config('mc.defaultNumPerPage'));

        return view('investments.index')
            ->with('investments', $investments)
            ->with('displaySearch', true)
            ->with('categories', ['' => trans('mc.all_categories')] + InvestmentCategory::getList())
            ->with('vendors', ['' => trans('mc.all_vendors')] + InvestmentVendor::getList())
    }

创建控制器文件：

<?php

namespace MC\Modules\Investments\Controllers;

use MC\Http\Controllers\Controller;
use MC\Modules\Investments\Models\Investment;

class InvestmentCreateController extends Controller
{
    public function create()
    {
        return view('investments.form')
            ->with('editMode', false)
            ->with('currentDate', DateFormatter::format(date('Y-m-d')))
    }

    public function store()
    {
        $record = request()->except('attachments');

        $record['investment_date'] = DateFormatter::unformat($record['investment_date']);
        $record['amount'] = NumberFormatter::unformat($record['amount']);
        $record['tax'] = ($record['tax']) ? NumberFormatter::unformat($record['tax']) : 0;

        $investment = Investment::create($record);

        return redirect($this->getReturnUrl())
            ->with('alertSuccess', trans('mc.record_successfully_created'));
    }
}

型号：

<?php

namespace MC\Modules\Investments\Models;

use Illuminate\Database\Eloquent\Model;

class Investment extends Model
{
    use Sortable;

    protected $table = 'investments';

    protected $guarded = ['id'];

    protected $sortable = ['investment_date', 'investment_categories.name', 'description', 'amount'];

    public static function boot()
    {
        parent::boot();
    }

    /*
    |--------------------------------------------------------------------------
    | Relationships
    |--------------------------------------------------------------------------
    */

    public function attachments()
    {
        return $this->morphMany('MC\Modules\Attachments\Models\Attachment', 'attachable');
    }

    public function category()
    {
        return $this->belongsTo('MC\Modules\Investments\Models\InvestmentCategory');
    }

    public function vendor()
    {
        return $this->belongsTo('MC\Modules\Investments\Models\InvestmentVendor');
    }

    /*
    |--------------------------------------------------------------------------
    | Accessors
    |--------------------------------------------------------------------------
    */

    public function getAttachmentPathAttribute()
    {
        return attachment_path('investments/' . $this->id);
    }

    public function getFormattedAmountAttribute()
    {
        return CurrencyFormatter::format($this->amount);
    }

    public function getFormattedTaxAttribute()
    {
        return CurrencyFormatter::format($this->tax);
    }

    public function getFormattedInvestmentDateAttribute()
    {
        return DateFormatter::format($this->investment_date);
    }


    /*
    |--------------------------------------------------------------------------
    | Scopes
    |--------------------------------------------------------------------------
    */

    public function scopeCategoryId($query, $categoryId = null)
    {
        if ($categoryId)
        {
            $query->where('category_id', $categoryId);
        }

        return $query;
    }

    public function scopeDefaultQuery($query)
    {
        return $query->select('investments.*', 'investment_categories.name AS category_name',
            'investment_vendors.name AS vendor_name', 'clients.unique_name AS client_name')
            ->join('investment_categories', 'investment_categories.id', '=', 'investments.category_id')
            ->leftJoin('investment_vendors', 'investment_vendors.id', '=', 'investments.vendor_id');
    }

    public function scopeVendorId($query, $vendorId = null)
    {
        if ($vendorId)
        {
            $query->where('vendor_id', $vendorId);
        }

        return $query;
    }
}

需要注意的一点是，我确实在表格中有现有数据，并且从我的网页查看时查询工作正常，但问题是在尝试编辑或插入新数据/记录时。

从上面的模型中可以看出，

投资。*'，'investment_categories.name AS category_name

该查询因该命令而起作用我找不到确定如何拍摄"investment_categories.name as category_name"的其他任何地方你能告诉我为什么它试图将category_name值写入investments表而不是investment_categories表的name列吗？

Laravel应用尝试在错误的列
