Laravel Save data one to one relationships with push()?

Question

Terms table:

• term_id
• name
• slug

Term_taxonomy table:

• term_taxonomy_id
• term_id
• description

My Term model:

public function TermTaxonomy(){
    return $this->hasOne('TermTaxonomy');
}

public function saveCategory($data){
    $validator = Validator::make($data,$this->rules);
    if($validator->passes()){
        $this->name = $data['name'];
        $this->slug = $data['slug'];
        $this->save();
        $TermTaxonomy = new TermTaxonomy;
        $TermTaxonomy->taxonomy = 'category';
        $TermTaxonomy->description = $data['TermTaxonomy']['description'];
        if($this->TermTaxonomy()->save($TermTaxonomy)){
            return true;
        }else{
            return false;
        }
        }else{
                return false;
        }
    }else{
        $this->errors = $validator;
        return false;
    } 
}

My TermTaxonomy model:

public function Term(){
    return $this->belongsTo('Term');
}

I have read Laravel 4 docs inserting related models

Sometimes you may wish to save not only a model, but also all of its relationships. To do so, you may use the push method:

Saving A Model And Relationships

$user->push();

See link here

Then I read @Antonio Carlos Answer in this question he says it can replace 2 save() syntax with push(), I think this good way because less code.

in my saveCategory() method it work like expected , but I want to know how I can use push() in my saveCategory() method? Already google that but nothing.

I am new in Laravel and any help will be appreciated.
