Call to undefined relationship in laravel

I have two tables departments and course, and I have defined a relationship between them but I received this error message:

Call to undefined relationship in laravel

Can anyone tell me please where's the problem?

Model Code:

public function course()
{
    return $this->hasMany('App\Course','departments_id','id');
}

Model Department:

public function department()
{
    return $this->belongsTo('App\Departments','departments_id');
}

in my case, i used:

::with('boards')

i just changed it to :

::with(['boards'])

with brackets

in my department Model:

public function boards()
{
    return $this->hasMany(Board::class);
}

First of all little correction in schema $table->integer('department_id'); should be $table->unsignedInteger('department_id');

And the problem is - in your migration column name is department_id but in your relation you have written departments_id there is a extra S!

just correct the column name from model.

So problem is so clear. Either in your Course model you have to rename the function department to departments, or to make a new one with the correct name.
