I need some methods to return true/false if a attribute had a value. So we have a date attribute #invited_on and I want an #invited? method to return true if the date is present.

There are a few dates for which I need this. My first attempt:

%w(invited_on selected_on confirmed_on ready).each do |attr|
  define_method attr.gsub('_on', '') + '?' do
    send(attr).present?
  end
end

As a default in the model

class MyModel < Sry::Struct

Using rsync from cron on server A to pull files from server B via ssh.

Server A has a passwordless private key, the public key is in authorized_keys on Server B.

I can ssh from Server A to Server B.

To prevent use of ForwardAgent specific no configuration file:

ssh -F /dev/null -v admin@servera

Create some files (via templating) on the server

- name: Create backup configuration files
  template:
    src: "{{ item.type }}.yml.j2"
    dest: "/tmp/{{ item.project }}_{{ item.env }}_{{ item.type }}.yml"
  with_items:
    - "{{ backup }}"
