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

From the text in the book:

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.
