Downloads the last 50 pages of Airbrake errors

download_airbrake_errors.rb

# Requires mechanize gem  (gem install mechanize)
# To use: 
#  1. Update this script w/ your site's login url, email, password, and project_id
#  2. gem install mechanize
#  3. ruby download_airbrake_errors.rb
#  4. Wait...  I didn't make this thing even remotely fast or efficient, since I don't need to use it that often.
#  5. It will download each error page to the /cache directory
#  6. Search it using your filesystem's built-in search capabilities.  The filenames are the ids of the error, so you can easily go to the real site for all of the related links


require 'mechanize'

EMAIL = "LOGIN_EMAIL"
PASSWORD = "LOGIN_PASSWORD"
PROJECT_ID = "PROJECT_ID" # Your site's errors page will look like this:  https://[PROJECT_NAME].airbrake.io/projects/[PROJECT_ID]/errors.  

m = Mechanize.new

login_form = login_page.form
login_form.field_with(:name => "session[email]").value = EMAIL
login_form.field_with(:name => "session[password]").value = PASSWORD

(1..50).each do |page_num|

Dir::mkdir("cache") unless File.exists?("cache")

current_page = 1
errors_pages.each do |page|
  p "Current Page: #{current_page}"
  error_links = page.links_with(:href => /errors\/(\d)+/).uniq{|link| link.href}

  error_links.each do |link|
    file_path = "cache/#{link.href.scan(/\d+$/).first}.html"
    next if File.exists?("file_path")
    page = link.click.save_as "cache/#{link.href.scan(/\d+$/).first}.html"
  end

  current_page += 1

Line 41 did you mean
next if File.exists?(file_path)
or
next if File.exists?("#{file_path}")
?
