Laravel Eloquent ->load() 未返回预期结果

Question

我的关系是这样设置的，

Organisation.php

public function projects()
    {
        return $this->belongsToMany('Project');
    }

Project.php

public function organisations()
    {
        return $this->belongsToMany('Organisation');
    }

我是运行下面的查询，

$project = Project::where('user_id', '=', ResourceServer::getOwnerId())
                    ->whereNull('organisation_id')
                    ->get(array(
                        'projects.id',
                        'projects.name', 
                        'projects.description',
                        'projects.total_cost',
                        'projects.sales_person', 
                        'projects.project_manager',
                        'projects.client_id',
                        'projects.start_date',
                        'projects.finish_date',
                        'projects.organisation_id',
                        'projects.created_at',
                        'projects.user_id',
                        'projects.owner_id',
                        'projects.status'
                    ));

        $project->load('salesperson');
        $project->load('projectmanager');
        $project->load('clients')->load('clients.users');
        $project->load('organisations')->load('organisations.users');
        $project->load('collaborators');
        $project->load('user');

        $owned_by_me = $project->toArray();

我得到的结果是这样的，

            }
        ]
    }

]

如您所见，organizations 属性是空的，但由于它有一个 organisation_id 它应该 return 一个组织。

为什么它不会做？

Answer 1

是belongsTo:

public function organisation()
{
    return $this->belongsTo('Organisation');
}

belongsToMany 是与枢轴 table 的 m-m 关系，这里不是这种情况，因为你有 organisation_id，对吧？像上面那样改变它就可以了。

在这种情况下，关系的另一端也应更改为 hasMany（尽管在您粘贴的代码中这不是问题）：

public function projects()
{
    return $this->hasMany('Project');
}
