【中文标题】SQLSTATE [42S22]：找不到列：在 laravel livewire 项目中

【英文标题】：SQLSTATE[42S22]: Column not found: in laravel livewire project

【问题描述】：

我正在尝试将导航菜单与导航类型同步，但我收到错误 Illuminate\Database\QueryException SQLSTATE[42S22]: Column not found: 1054 Unknown column ' navigation_menu_id' in 'field list' (SQL: insert into 'navigation_menus_navigation_types' (' navigation_menu_id', 'navigation_type_id') values (1, 1))

我不确定为什么没有找到 navigation_menu_id。我正在使用带有自定义外键 ID 的自定义数据透视表。

*Migration.php

Schema::create('navigation_menus_navigation_types', function (Blueprint $table) 
$table->id('navigation_menus_navigation_types_id');

$table->unsignedBigInteger('navigation_menu_id');
$table->foreign('navigation_menu_id')->references('navigation_menus_id')->on('navigation_menus');

$table->unsignedBigInteger('navigation_type_id');
$table->foreign('navigation_type_id')->references('navigation_menu_types_id')->on('navigation_menu_types');
$table->timestamps(); );

NavigationMenu Model.php

class NavigationMenu extends Model 
protected $primaryKey = 'navigation_menus_id';

public function navigationType()

    return $this->belongsToMany(NavigationMenuType::class,'navigation_menus_navigation_types','navigation_type_id',' navigation_menu_id');

导航菜单类型 Model.php

class NavigationMenuType extends Model
protected $primaryKey = 'navigation_menu_types_id';

public function navigationMenu()

    return $this->belongsToMany(NavigationMenu::class,'navigation_menus_navigation_types',' navigation_menu_id','navigation_type_id');

PagesNavigation Controller.php

public function syncNavtypes()
        $this->seletedNavigationMenu = NavigationMenu::find($this->navMenuId);
        $this->seletedNavigationMenu->navigationType()->sync($this->navTypeId);
        $this->modelSyncNavigationTypesVisible = false;
        $this->reset();
        $this->resetValidation();

【问题讨论】：

投票结束这个问题，因为它是一个错字，在你的NavigationMenu 模型中有一个额外的空间' navigation_menu_id'

【参考方案1】：

我认为你们关系中的问题：

public function navigationType()

    return $this->belongsToMany(NavigationMenuType::class,'navigation_menus_navigation_types','navigation_type_id',
' navigation_menu_id');  // here!!

问题是您在列名的开头添加了额外的空格， 目前 laravel 会信守承诺！！

你只需要删除多余的空间。

public function navigationType()

    return $this->belongsToMany(NavigationMenuType::class,'navigation_menus_navigation_types','navigation_type_id',
'navigation_menu_id');  

【参考方案2】：

如果没有其他问题，则问题已解决。你会在你的关系中增加一个空间 -

' navigation_menu_id'

return $this->belongsToMany(NavigationMenuType::class,'navigation_menus_navigation_types','navigation_type_id','navigation_menu_id');

【讨论】：

谢谢！我没有意识到我在那里有一个空间

那是输入错误。 :)
