Ignore this. I was able to solve this. RETURN was missing in the models.

Unit Model:

namespace App\Models\Qualification;

use Illuminate\Database\Eloquent\Model;

class Unit extends Model {

  //
  protected $table = "unit";

  public function qualifications()
  {
  	$this->belongsToMany('\App\Models\Qualification', 'qualification_unit_xref');
  }

}


qualification model:

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Qualification extends Model {

public $timestamps = false; protected $table = "qualification";

// get the related training package it belong public function trainingpackage() { $this->belongsTo('\App\Models\TrainingPackage', 'package_id'); }

// get the units part of the qualification public function units() { $this->belongsToMany('\App\Models\Qualification\Unit', 'qualification_unit_xref', 'qualification_id', 'unit_id'); }

// get the industries associated with the qualification public function industries() { $this->belongsToMany('\App\Models\Qualification\Industry', 'qualification_industry_xref'); }

// get the occupation associated with qualification public function occupations() { $this->belongsToMany('\App\Models\Qualification\Occupation', 'qualification_occupation_xref'); } }


Controller function:

public function all() {

  $qualifications = Qualification::with('units', 'trainingpackage')->get();
  

}


On executing I'm getting the following stack trace.

[2015-04-14 01:23:38] production.ERROR: exception 'Symfony\Component\Debug\Exception\FatalErrorException' with message 'Call to a member function addEagerConstraints() on a non-object' in C:\xampp\htdocs\gqtool\vendor\laravel\framework\src\Illuminate\Database\Eloquent\Builder.php:439 Stack trace: #0 C:\xampp\htdocs\gqtool\storage\framework\compiled.php(1721): Illuminate\Foundation\Bootstrap\HandleExceptions->fatalExceptionFromError(Array) #1 [internal function]: Illuminate\Foundation\Bootstrap\HandleExceptions->handleShutdown() #2 {main}

Can I get any help in resolving this?

You need to return the statements inside the model functions.

so, the function below public function qualifications() { $this->belongsToMany('\App\Models\Qualification', 'qualification_unit_xref'); }

should be

public function qualifications() { return $this->belongsToMany('\App\Models\Qualification', 'qualification_unit_xref'); }
