Agile Web Development with Rails 7: Page 103 on the pdf
This may or may not be Errata but we have in one place
validates :image_url, allow_blank: true
and above that we have
validates :title, :description, :image_url, presence: true
So in once place it says the image_url is blank and in another place it says that its presence is required
Marked As Solved

Note that we use the allow_blank option to avoid getting multiple error messages when the field is blank.
While weird, it also seems weird to validate two of the three fields on the presence: true line and the third field on a different line.
