/*******************************************************************/
public function RankList()
{
return $this->hasMany('App\Models\RankList','user_id');
}
public function Company()
{
return $this->hasMany('App\Models\Company');
}
public function newsAndEvents()
{
return $this->hasMany('App\Models\newsAndEvents','user_id');
}
/********************************************************************/
/* Relationship between User and user type */
/*******************************************************************/
public function UserType()
{
return $this->belongsTo('App\Models\UserType','user_type_id');
}
public function course_outline()
{
return $this->belongsTo('App\Models\CourseOuline','user_id');
}
public function Jobs()
{
return $this->belongsToMany('App\Models\Job','Job_User','User_id','Job_id');
}
public function Skill_User()
{
return $this->belongsToMany('App\Models\Skill','Skill_User','Skill_id','User_id');
}
public function Feedback_User()
{
return $this->belongsToMany('App\Models\Feedback','Feedback_User','Feedback_id','User_id');
}
}
in job model method is
class Job extends Model
{
use SoftDeletes;
protected $dates = ['deleted_at'];
/**************************************************/
/* Company Post Job */
/**************************************************/
protected $fillable = [
'jobType', 'jobTitle','skills','industry', 'department', 'vacancy', 'qualification', 'degreeTitle', 'miniExperience', 'jobCategory',
'city', 'gender', 'companyName', 'description','posting_date', 'applied_date', 'companyLogo',
];
protected $table = 'jobs';
/**************************************************/
/* Relationships between company and job */
/**************************************************/
public function Company()
{
return $this->belongsTo('App\Models\Company','company_id');
}
public function job_skill()
{
return $this->belongsToMany('App\Models\Skill','Job_Skill','Job_id','skill_id');
}
public function Users()
{
return $this->belongsToMany('App\Models\User','Job_User','User_id','Job_id');
}
}
pivot table code is
class Job_User extends Model
{
protected $fillable = [
'cv','current_salary','expected_salary','status',
];
protected $table = 'jobs_users';
}
but user apply on job error is shown
Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (bridging_the_gap.jobs_users, CONSTRAINT jobs_users_user_id_foreign FOREIGN KEY (user_id) REFERENCES users (id) ON DELETE CASCADE ON UPDATE CASCADE) (SQL: insert into jobs_users (cv, current_salary, expected_salary, updated_at, created_at) values (1st, 15,000-19,999, 30,000-39,999, 2016-06-02 10:57:02, 2016-06-02 10:57:02))

Answer 1

Try something like this
//model jobs
public function Jobs()
{
return $this->belongsToMany('App\Models\jobs_users');
}
//model users
public function Users()
{
return $this->belongsToMany('App\Models\jobs_users');
}
//model pivot - jobs_users
public function user() {
return $this->belongsTo('App\Models\user');
}
public function jobs() {
return $this->belongsTo('App\Models\job');
}
This are basics to make pivot (many to many relation). For more fields you have to define in pivot model extra fields etc...
Hope it helps
