Question

我的迁移中有以下内容：

public function up()
{
    Schema::create('plan_submissions', function (Blueprint $table) {
        $table->bigIncrements('id');
        //This is the advisor_id for the advisor who created the Plan Submission
        $table->unsignedBigInteger('advisor_id')->index();
        $table->timestamps();
        $table->softDeletes();

        $table->foreign('advisor_id')->references('id')->on('advisors');

我的计划提交模型中包含以下内容：

    public function advisor()
{
    return $this->belongsTo(Advisor::class);
}

顾问模型的主键是'id'。

我的控制器中的If / Else语句中包含以下内容：

        elseif (request('advisor_last_name')) {
        PlanSubmission::whereHas('advisor', function ($query) {
            $query->where('last_name', request('advisor_last_name'))->paginate(25)->appends('advisor_last_name', request('advisor_last_name'));
        });

我收到以下错误消息：

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'plan_submissions.advisor_id' in 'where clause' (SQL: select count(*) as aggregate from `advisors` where `plan_submissions`.`advisor_id` = `advisors`.`id` and `last_name` = bayne)

我不明白为什么会出现此错误消息

Answer 1

在您的计划提交模型中尝试

public function advisor() 
{
  $this->belongsTo('App\Advisor', 'advisor_id', id);
}

雄辩无法识别表名
