Php 如何在laravel中建立关系
我对laravel不熟悉，我在尝试连接此表时遇到问题：Php 如何在laravel中建立关系,php,laravel,laravel-5,Php,Laravel,Laravel 5,我对laravel不熟悉，我在尝试连接此表时遇到问题：计划、用户和贷款，即使在阅读文档之后 我有一个计划表，其中包含我所有的计划，然后我有一个用户表和贷款表，我的贷款表有一个用户id和计划id，我只想在贷款模型中提取计划和用户的记录 Loanplan.php <?php namespace App; use Illuminate\Database\Eloquent\Model; class Loanplan extends Model { // protected $

首先，您必须检查模型是否已经从您之前创建的表中进行了查询。Laravel将根据您的类名自动访问表
请注意，我们没有告诉Eloquent我们的飞行
模型使用哪个表。按照惯例，除非明确指定了另一个名称，否则类的复数名“snake-case”将用作表名。因此，在这种情况下，Eloquent将假定Flight
模型在flights
表中存储记录
你可以从报纸上读到
其次，确保你给正确的班级打电话。在loan（）
方法中的Loanplan.php
中，第一个字母不使用大写字母
第三，尝试声明外键和主键。您还可以在文档中检查如何执行此操作。首先，您必须检查模型是否已经从您之前创建的表中进行了查询。Laravel将根据您的类名自动访问表

缺少protected$table=“plans”
变量
同一个文件
public function loan()
{
return $this->belongsTo('App\loan');
}
关系应该是一对或多对，而不是一对
此外，类的名称应使用大写字母L进行贷款
public function loan()
{
return $this->...('App\Loan');
}

我认为问题在于Loanplan
模型中loans
表名的定制
根据您的描述，您需要以下设置：
用户可以访问一个或多个贷款
用户
1--m计划
贷款
属于贷款计划
//这里我使用贷款计划
，因为这是您的型号名称。
贷款
1--m计划
因此，这意味着：

<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Loan extends Model
{
protected $table = 'loans';
//
protected $fillable = [

{
return $this->belongsTo('App\User');
}
public function loanplan()
{
return $this->belongsTo('App\Loanplan');
}
}
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class User extends Model
