Laravel Eloquent - > load（）没有返回预期的结果

Question

I have relationship that is setup like this,

Organisation.php

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

Project.php

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

I am running the following query,

$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();

The results I get back looks like this,

        ]
    }

As you can see the organisations attribute is empty, but by the virtue that is has an organisation_id it should return an organisation.

Why would it not be doing?

Answer 1

It's belongsTo:

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

belongsToMany is a m-m relation with pivot table, which is not the case here, since you have organisation_id, right? Change it as above and you're good to go.

In this case also the other side of the relationship should be changed to hasMany (although it is not a problem in the code you pasted):

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