Hi everyone,
I am a total novice with Ruby on Rails and I'm having a problem using validates_presence_of. I'm following a tutorial from a book called "Ruby on rails: up and running" and I'm not getting the result I expect (and what the book expects).
Here's my model: class Photo < ActiveRecord::Base validates_presence_of :filename end
I tested this using rails console:
photo=Photo.new
=> #<Photo id: nil, filename: nil>
photo.save
=> true
puts photo.filename
nil
I expect (and so does the book) that photo.save returns false and
nothing is saved to the database, but it saves anyway. Any ideas what I
am doing wrong? Forgive me if it's something ridiculously simple that
I've overlooked, it is quite late 
If you could point me in the right direction I would be greatly
appreciative.
Cheers, Adam
