I would like to read the deleted statuses on twitter since i can already have the user_id and status_id of the deleted tatus using "on_delete" method.
here is my code:
require 'rubygems'
require 'tweetstream'
TweetStream::Client.new(USER,PASS).follow(3331681,15846407,30592818,21249843,1367531,428333, 196218494,82158673, :delete => Proc.new{ |status_id, user_id| puts "#{status_id}, #{user_id}"}) do |status|
#is it a retweet
rt=!defined?(status.method_missing("retweeted_status",status.id).class).nil?
puts "retweet?:"
puts rt.inspect
if status.in_reply_to_screen_name.nil?
if rt
puts "Retweeted by :#{status.user.screen_name}"
else
puts "Screen name :#{status.user.screen_name}"
end
else
puts "From :#{status.user.screen_name} to #{status.in_reply_to_screen_name}"
end
puts "Text:#{status.text}"
puts "#{status.created_at}"
puts '*' * 7
puts "user id:#{status.user.id}"
puts "to :#{status.in_reply_to_user_id}"
puts '--' * 25
end
No, you can't. This is a constraint of the Twitter API rather than any Ruby library. It used to be possible but has since been fixed, breaking tweet recovery services such as tweleted.com in the process.

I've been working for a while to try to use the .uniq method to generate a unique list of URL's from a website (within the /informatics path). No matter what I try I get a method error when trying to generate the list. I'm sure it's a syntax issue, and I was hoping someone could point me in the right direction.
Once I get the list I'm going to need to store these to a database via ActiveRecord, but I need the unique list before I get start to wrap my head around that.
require 'nokogiri'
require 'open-uri'
require 'active_record'
ARGV[0]="https://www.nku.edu/academics/informatics.html"
ARGV.each do |arg|
open(arg) do |f|
# Display connection data
puts "#"*25 + "\nConnection: '#{arg}'\n" + "#"*25
[:base_uri, :meta, :status, :charset, :content_encoding,
:content_type, :last_modified].each do |method|
puts "#{method.to_s}: #{f.send(method)}" if f.respond_to? method
end
# Display the href links
base_url = /^(.*\.nku\.edu)\//.match(f.base_uri.to_s)[1]
puts "base_url: #{base_url}"
Nokogiri::HTML(f).css('a').each do |anchor|
href = anchor['href']
# Make Unique
if href =~ /.*informatics/
puts href
#store stuff to active record
end
end
end
end
Replace the Nokogiri::HTML part to select only those href attributes that matches with /*.informatics/ and then you can use uniq, as it's already an array:
require 'nokogiri'
require 'open-uri'
require 'active_record'
ARGV[0] = 'https://www.nku.edu/academics/informatics.html'
ARGV.each do |arg|
open(arg) do |f|
puts "#{'#' * 25} \nConnection: '#{arg}'\n #{'#' * 25}"
%i[base_uri meta status charset content_encoding, content_type last_modified].each do |method|
puts "#{method.to_s}: #{f.send(method)}" if f.respond_to? method
end
puts "base_url: #{/^(.*\.nku\.edu)\//.match(f.base_uri.to_s)[1]}"
anchors = Nokogiri::HTML(f).css('a').select { |anchor| anchor['href'] =~ /.*informatics/ }
puts anchors.map { |anchor| anchor['href'] }.uniq
end
end
See output.
I apologies if this is simple but I'm just starting out. Any constructive help welcome.
Problem:
Trying to create authentication from ruby terminal to CSV.
I'd like to create clean (and as short as possible) loop statement that goes to csv file checks the top row for header "pin" and then checks the gets.chomp entry against that to authenticate.
require 'csv'
class Menu
def self.login
system "clear"
puts "Welcome to Hip-Bikes & Coffee"
puts "Please login with your pin:"
print "> "
customer_pin = gets.chomp
verified = authentication(customer_pin)
end
def self.authentication(customer_pin)
case
when CSV.foreach('customers.csv', headers: true) { |row| ["pin"] == login.verified }
puts verified
else
puts "login failed. Please try again in 3 seconds..."
sleep(3.0)
self.login
This should work for you
UPD
require 'csv'
class Menu
class << self
def login
login_start
verified(gets.chomp)
end
def verified(input)
if authentication(input)
puts 'verified'
else
failed
end
end
def authentication(customer_pin)
CSV.foreach('customers.csv', headers: true).any? { |row| row['pin'] == customer_pin }
end
def failed
puts "login failed. Please try again in 3 seconds..."
sleep(3.0)
login
end
def login_start
system "clear"
print "Welcome to Hip-Bikes & Coffee\nPlease login with your pin:\n> "
end
end
end
I am trying to run different code using randomly generated types. Creating random types (self.type) works. However, I want to use these types: Early, Late or On Time to conditionally run code based on the string self.type returns. Thanks in advance!
require 'rubygems'
require 'forgery'
class Forgery::MyRecord< Forgery
TYPES= Forgery::Extend([
{ :type => "Early" },
{ :type => "Late" },
{ :type => "On Time" }
])
def self.type
TYPES.random[:type]
end
a=self.type
puts a
This works up to this line of code. It randomly returns Early, Late or On Time.
But, how can I use type in my method? Thanks!
def self.deadline
if self.type=="Early"
puts "early"
#removed other code
elsif if self.type=="Late"
puts "late"
#removed other code
elsif if self.type=="On Time"
puts "on time"
#removed other code
else
puts "Missing"
end
end
b = Forgery::MyRecord.deadline
puts b
end
end
Your problem is: Every time you call type it returns a random value. Therefore you check against different values in each if condition.
Change your code to this:
def self.deadline
case type
when "Early"
puts "early"
# removed other code
when "Late"
puts "late"
#removed other code
when "On Time"
puts "on time"
#removed other code
else
puts "Missing"
end
end
Am trying to implement amazon SNS using ruby.
I want to create a topic,delete a topic,subscribe to a topic,publish to a topic.These are included in the following code.
#!/usr/bin/env ruby

I'm converting a generator over from RubiGen and would like to make it so the group of tasks in Thor::Group does not complete if a condition isn't met.
The RubiGen generator looked something like this:
def initialize(runtime_args, runtime_options = {})
super
usage if args.size != 2
#name = args.shift
#site_name=args.shift
check_if_site_exists
extract_options
end
def check_if_site_exists
unless File.directory?(File.join(destination_root,'lib','sites',site_name.underscore))
$stderr.puts "******No such site #{site_name} exists.******"
usage
end
end
So it'd show a usage banner and exit out if the site hadn't been generated yet.
What is the best way to recreate this using thor?
This is my task.
class Page < Thor::Group
include Thor::Actions
source_root File.expand_path('../templates', __FILE__)
argument :name
argument :site_name
argument :subtype, :optional => true
def create_page
check_if_site_exists
page_path = File.join('lib', 'sites', "#{site_name}")
template('page.tt', "#{page_path}/pages/#{name.underscore}_page.rb")
end
def create_spec
base_spec_path = File.join('spec', 'isolation', "#{site_name}")
if subtype.nil?
spec_path = base_spec_path
else
spec_path = File.join("#{base_spec_path}", 'isolation')
end
template('functional_page_spec.tt', "#{spec_path}/#{name.underscore}_page_spec.rb")
end
protected
def check_if_site_exists # :nodoc:
$stderr.puts "#{site_name} does not exist." unless File.directory?(File.join(destination_root,'lib','sites', site_name.underscore))
end
end
after looking through the generators for the spree gem i added a method first that checks for the site and then exits with code 1 if the site is not found after spitting out an error message to the console. The code looks something like this:
def check_if_site_exists
unless File.directory?(path/to/site)
say "site does not exist."
exit 1
end
end
