Joining Model with Table Laravel 5.2

I have created a model in Laravel.

class deals extends Model
{
//
protected $table = 'tbl_deal';
}

Now I want to use this model to retrieve data in my Controller. However, the data extracted from this model also needs to be constrained by a column in another table. Below is the basic schema

tbl_deal

• deal_id
• merchant_id
• deal_text

tbl_merchant

• merchant_id
• merchant_url_text

My current Controller has the following code to extract all deals from deals model.

$deals = deals::all();

I want to constraint the deals by merchant_url_text. Since that is in merchant table, I would need to join it with the existing deal model.

Any help on how I can do that in my controller and if this is the right way to solve this kind of problem.

Thanks.
