• Simple cropping with Paperclip

  - by collimarco

  I would like to crop images on upload using Paperclip to get square thumbs from the center of the original picture. I find out a method in documentation that seems to do exactly what I want: transformation_to(dst, crop = false) The problem is that I can't figure out where to use this method. It would be great to simply pass something as a parameter here: has_attached_file :picture, :styles = { :medium = "600x600", :thumb = "something here" }

  - by collimarco

  I have a site built in Ruby On Rails which has many ads in different templates and views. It is hard to actualy remove each ad between tests and deployments. I don't know whether Google approves many impressions (even if without clicks) on localhost. How do you deal with this issue? Maybe it is a good solution to set a variable/constant available everywere to enable/disable ads easily. Do you think it is a good solution? If so, how do I declare a global variable for views?
