Laravel 5 | 一对多关系查询错误

Question

I've created a one-to-many relationship between a Jobs Model and Permits model. I've recently discovered the awesome tool of Tinker so I've been using it to test my models. When I run Job::with('steps')->find(1); I get this error

Illuminate\Database\QueryException with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'steps.job_id' in 'where clause' (SQL: select * from `steps` where `steps`.`job_id` in (1))'

Here's my Job Model

   public function steps ()
    {
        return $this->hasMany('MyfirstApp\Step');
    }

Here's my Step Model

   public function Job ()
    {
      return $this->belongsTo('MyFirstApp\Job');
    }

I've already set up the foregin key in the Jobs Table so I'm not sure what the error can be. Any ideas?

Table Structure for reference

Answer 1

For your relationship, Job has many Steps, you have assigned wrong foreign key.

In your case steps table should contain job_id rather than job contains steps_id.

Solution:

• Remove steps_id from job table.
• Set job_id in steps table as a foreign key.
