Answer 1

Did you precomple your assets.As in production,the rails looks for assets in public folder and not in assets folder.i might be wrong but it can be because of asset pipeline.You can resolve this by manually adding the image in public folder and then running rake assets:precompile so that it is available in public folder. Morever,for the same stuff to handle default picture,you can use my code as well.

###in picture.rb
## belongs_to :user
MISSING_PICTURE_URL = '/assets/picture_missing.png'

##in user.rb
##has_many :pictures
def get_picture_url
  self.pictures.exists? ? self.pictures.sample.picture.expiring_url(:medium) : Picture::MISSING_PICTURE_URL

end

so i can easily use @user.get_picture_url and it works great. Also one more thing to note here,i am using use exists? and not present?
