you don't need to make a relation in project_assign model. only Project and User will have relation,

Project Model

public function users(){
   return $this->belongsToMany('App\User','project_assign','project_id','user_id');
}

User Model

public function projects(){
    return $this->belongsToMany('App\Project','project_assign','user_id','project_id');
}

In controller you can get like this

User::with('projects')->get();
Project::with('users')->get();
