Laravel 销毁嵌套资源

Question

我有一个资源名称OrganizationEmailDomain

Route::resource('organizations.emaildomains', 'OrganizationEmailDomainController', ['except' => ['show']]);

并且能够很好地索引它

在那个视图中，当点击三个点时，会出现破坏部分

<form action="{{ route('organizations.emaildomains.destroy', ['organization' => $id, 'emaildomain' => $email_domain->id]) }}" method="post">
    @csrf
    @method('delete')
    <button type="button" class="dropdown-item" onclick="confirm('{{ __("Are you sure you want to delete this email domain?") }}') ? this.parentElement.submit() : ''">
        {{ __('Delete') }}
    </button>
</form>

如果在该索引视图中我回显 $email_domains (<?php echo $email_domains;?>)，那么我得到了预期的结果（请注意，以下是在添加图像之前，因此记录与图像不匹配）

[{"id":1,"email_domain":"test.com","organization_id":1,"created_at":"2021-03-02T14:46:50.000000Z","updated_at":"2021-03-02T14:46:56.000000Z"},{"id":2,"email_domain":"gmail.com","organization_id":1,"created_at":null,"updated_at":null}]

当我试图破坏时

/**
 * Remove the specified resource from storage.
 *
 * @param  \App\OrganizationEmailDomain  $emailDomain
 * @return \Illuminate\Http\Response
 */
public function destroy(Organization $organization, OrganizationEmailDomain $emailDomain)
{
    //dd($emailDomain);

    $emailDomain->delete();

    return redirect()->route('organizations.emaildomains.index',$organization->id)->withStatus(__("Organization's email domain successfully deleted."));
}

dd($emailDomain) 返回这个

正如langbox 状态

(...) hasMany 关系 (...) 所以它返回一个集合 always

所以，灵感来自 this answer from Dan，只是替换

$emailDomain->delete();

以下

$org_email = OrganizationEmailDomain::where('id', $organization->org_email_domains->pluck('id'))->delete();

鉴于我在组织模型中拥有

/**
 * Get the email domains of the organization
 *
 * @return void
 */
public function org_email_domains()
{
    return $this->hasMany(OrganizationEmailDomain::class);
}

这里有什么问题？

它总是删除上面一行中的记录。

比如我们删除DDDDDDDDDDDDDDDDDDD

这删除了第一行，AAAAAAAAAAAAAAAAA

如果我尝试删除BBBBBBBBBBBBBBB（现在已成为第一行），它会很好地删除。

作为参考，这里是我之前共享的表单所在的 index.blade.php

<table class="table table-flush"  id="datatable-basic">
    <thead class="thead-light">
        <tr>
            <th scope="col">{{ __('Organization') }}</th>
            <th scope="col">{{ __('Email Domain') }}</th>
            <th scope="col">{{ __('Creation date') }}</th>
            @can('manage-org-emaildomains', App\User::class)
                <th scope="col"></th>
            @endcan
        </tr>
    </thead>
    <tbody>
        @foreach ($email_domains as $email_domain)
            <tr>
                <td>{{ $organization->name }}</td>
                <td>{{ $email_domain->email_domain }}</td>

Answer 1

你不能只删除 id，你只传递了 id。

在控制器中你必须做 Find ，例如：

$flight = Flight::find($emaidomain);

那你做

$flight->delete();

你只是在表单中传递了id，你必须通过id找到控制器中的项目然后删除，你不能只删除id。

Answer 2

我已将路线更改为shallow nesting

Route::resource('organizations.emaildomains', 'OrganizationEmailDomainController', ['except' => ['show']])->shallow();

然后表格到

<form action="{{ route('emaildomains.destroy', ['organization' => $id, 'emaildomain' => $email_domain->id]) }}" method="post">
    @csrf
    @method('delete')
    <button type="button" class="dropdown-item" onclick="confirm('{{ __("Are you sure you want to delete this email domain?") }}') ? this.parentElement.submit() : ''">
        {{ __('Delete') }}
    </button>
</form>

和destroy()到

/**
 * Remove the specified resource from storage.
 *
 * @param  \App\OrganizationEmailDomain  $emailDomain
 * @return \Illuminate\Http\Response
 */
public function destroy(Request $request, OrganizationEmailDomain $emailDomain)
{
    $path = $request->path();

    $id = substr($path, strrpos($path, '/') + 1);

    $emailDomain = OrganizationEmailDomain::find($id);

    $emailDomain->delete();

    return redirect()->route('organizations.emaildomains.index',$request->query()['organization'])->withStatus(__("Organization's email domain successfully deleted."));
}

现在它可以正常工作了。
