Check whether a Paperclip attachment exists

Don’t simply test for the presence of the magic Paperclip attribute, it will return a paperclip Attachment object and thus always be true:

- if user.photo.present? # always true
  = image_tag(user.photo.url)

kyledrake

require 'tempfile'
require 'openssl'
require 'escape' # gem install escape

class CommandFailError < StandardError; end

def p12_to_pem_text(p12, pass='')
  pass = '' if pass.nil?

  # Use shell command for JRuby (see https://github.com/jruby/jruby-ossl/issues/8)

Abstract

You could have postgre installed on localhost with password (or without user or password seted after instalation) but if we are developing we really don't need password, so configuring postgre server without password for all your rails project is usefull.

Install Postgre packages

• postgresql
• postgresql-client
• libpq-dev
