I am adding to an array using:
server.bans << { :mask => "#{user}", :who => "#{server}", :when => Time.now.to_i }
What is the simplest method to reverse this command?
Should I be using .remove? If so what should I pass to it, the same as what I used in the <<?
You can also use Array#delete_if, if you want to remove elements which meet certain criteria:
server.bans.delete_if{ |u| u[:mask] == "#{user}" }
You could get the object_id of each element in the Array to use as a future reference. While using pop will work, it is not available once another element of the Array is added.
To view object_id of elements. Possibly store these in it's own Array.
server.bans do |ban|
puts ban.object_id
end
Ruby array provide delete_if method to delete items from array conditions. You can use this method as
server.bans.delete_if{ |u| u[:mask] == user.to_s }
To get more details of delete_if http://ruby-doc.org/core-2.2.2/Array.html#method-i-delete_if
Further you can also user remove! method
to_s, which is incorrect)?
