Filtering and value in Rails?

Question

Ruby on Rails

Hello. Is it possible in Rails, what if the value is not found, then what would return a null value, and not fall into an error?

count = products.find_by( date: '2017-05-16' ).count

Of course, you can do it like this, but maybe there is a more elegant solution?

product = products.find_by( date: '2017-05-16' )
count = product.present? ? product .count : 0

Answer 1

Product.where(date: '2017-05-16').count # => 0
