本文介绍了Laravel雄辩的分页关系的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

  $ query = Product :: find(1) - > ;选项() - >分页(); 

但是我收到以下错误:

 致命错误:调用非对象的成员函数getCurrentPage()

我已经确认代码 $ query = Product :: find(1) - > options()返回一组选项。 $ query 对象似乎是类型 hasMany 。以下是我正在使用的示范类。

  class产品扩展Eloquent 
{

保护$ table ='products';

public function options()
{
return $ this-> hasMany('ProductOption','product_id');
}
}

class ProductOption extends Eloquent
{
protected $ table ='product_options';

public function product()
{
return $ this-> belongsTo('Product','product_id');
}
}

雄辩没有为关系返回分页结果? p>

解决方案

你不能懒惰地加载关系分页,而是在你的产品模型中放下下面的功能你的选项有很多关系



  public function getOptionsPaginatedAttribute()
{
return $ this-> options() - > paginate 10);
}

这将允许您调用您的关系数据的分页

  $ product-> options_paginated 


I am trying to paginate a Eloquent relationship like this:

 $query = Product::find(1)->options()->paginate();

But I get the following error:

Fatal error: Call to a member function getCurrentPage() on a non-object

I have confirmed that the code $query = Product::find(1)->options() returns a collection of options. The $query object seems to be of type hasMany. Below are the model classes I am using.

class Product extends Eloquent
{

    protected $table = 'products';

    public function options ()
    {
        return $this->hasMany('ProductOption', 'product_id');
    }
}

class ProductOption extends Eloquent
{
    protected $table = 'product_options';

    public function product()
    {
        return $this->belongsTo('Product', 'product_id');
    }
}

Does eloquent not return paginated results for relationships?

解决方案

You can not lazy load relational pagination like that, instead in your Product Model put the following function below your options has many relationship

public function getOptionsPaginatedAttribute()
{
    return $this->options()->paginate(10);
}

This will allow you to call the pagination on your relational data by

$product->options_paginated
