  • Errors when connecting to HTTPS using HTTP::Net routines (Ruby on Rails)

    - by jaycode
    Hi all, the code below explains the problem in detail #this returns error Net::HTTPBadResponse url = URI.parse('https://sitename.com') response = Net::HTTP.start(url.host, url.port) {|http| http.get('/remote/register_device') } #this works url = URI.parse('http://sitename.com') response = Net::HTTP.start(url.host, url.port) {|http| http.get('/remote/register_device') } #this returns error Net::HTTPBadResponse response = Net::HTTP.post_form(URI.parse('https://sitename.com/remote/register_device'), {:text => 'hello world'}) #this returns error Errno::ECONNRESET (Connection reset by peer) response = Net::HTTP.post_form(URI.parse('https://sandbox.itunes.apple.com/verifyReceipt'), {:text => 'hello world'}) #this works response = Net::HTTP.post_form(URI.parse('http://sitename.com/remote/register_device'), {:text => 'hello world'}) So... how do I send POST parameters to https://sitename.com or https://sandbox.itunes.apple.com/verifyReceipt in this example? Further information, I am trying to get this working in Rails: http://developer.apple.com/iphone/library/documentation/NetworkingInternet/Conceptual/StoreKitGuide/VerifyingStoreReceipts/VerifyingStoreReceipts.html#//apple_ref/doc/uid/TP40008267-CH104-SW1

  • Ruby on Rails questionnaire tutorial?

    - by kovrik
    Can't find any tutorial for creating a simple questionnaire system on RoR (without using Finite State Machines). I think the Model is simple: Quizzes (have many Questions) Questions (belong to Quizzes, have many Choices, have one Answer) Choices (belong to Questions) Responses (belong to Users, belong to Questions) Users (have many Responses). User logs in (session is created), chooses some Quiz (Questions which belong to this Quiz are shown). User navigates through the Questions, makes his choice (Response), finishes the Quiz. Responses are compared with Answers. System shows some results. But as I'm new to Rails it is difficult for me to make it work properly. Any help? Maybe there is a tutorial where some similar app is created?

  • Using Unix Process Controll Methods in Ruby

    - by John F. Miller
    Ryan Tomayko touched off quite a fire storm with this post about using Unix process control commands. We should be doing more of this. A lot more of this. I'm talking about fork(2), execve(2), pipe(2), socketpair(2), select(2), kill(2), sigaction(2), and so on and so forth. These are our friends. They want so badly just to help us. I have a bit of code (a delayed_job clone for DataMapper that I think would fit right in with this, but I'm not clear on how to take advantage of the listed commands. Any Ideas on how to improve this code? def start say "*** Starting job worker #{@name}" t = Thread.new do loop do delay = Update.work_off(self) break if $exit sleep delay break if $exit end clear_locks end trap('TERM') { terminate_with t } trap('INT') { terminate_with t } trap('USR1') do say "Wakeup Signal Caught" t.run end end

  • Strange ruby behavior when using Hash.new([])

    - by Valentin Vasilyev
    Consider this code: h=Hash.new(0) #new hash pairs will by default have 0 as values h[1]+=1 # {1=>1} h[2]+=2 # {2=>2} that's all fine, but: h=Hash.new([]) #empty array as default value h[1]<<=1 #{1=>[1]} - OK h[2]<<=2 #{1=>[1,2], 2=>[1,2]} # why ?? At this point I expect the hash to be: {1=>[1], 2=>[2]} But something goes wrong. Does anybody know what happens?

  • Ruby &&= edge case

    - by Alan O'Donnell
    Bit of an edge case, but any idea why &&= would behave this way? I'm using 1.9.2. obj = Object.new obj.instance_eval {@bar &&= @bar} # => nil, expected obj.instance_variables # => [], so obj has no @bar instance variable obj.instance_eval {@bar = @bar && @bar} # ostensibly the same as @bar &&= @bar obj.instance_variables # => [:@bar] # why would this version initialize @bar? For comparison, ||= initializes the instance variable to nil, as I'd expect: obj = Object.new obj.instance_eval {@foo ||= @foo} obj.instance_variables # => [:@foo], where @foo is set to nil Thanks!

  • Shortcut for rake db:migrate:down for ruby-on-rails

    - by Michaël
    Hi, I want to know if there is a short way to do the migrations down equivalent to rake db:migrate (for the migrations up). Instead of doing : rake db:migrate:up VERSION=1, rake db:migrate:up VERSION=2, ... we can do : rake db:migrate! But for : rake db:migrate:down VERSION=10, rake db:migrate:down VERSION=..., rake db:migrate:down VERSION=1, is there a shortcut? Tank you for your help!

  • Trying to execute netdom.exe from a ruby script or IRB does nothing

    - by Joraff
    I'm trying to write a script that will rename a computer and join it to a domain, and was planning to call on netdom.exe to do the dirty work. However, trying to run this utility in the script (same results in irb) does absolutely nothing. No output, no execution. I tried with backticks and with the system() method. System() returns false for everything but system("netdom") (which returns true). Backticks never return anything but an empty string. I have verified that netdom runs and works in the environment the script will be running in, and I'm calling other command-line utilities earlier in the script that work (w32tm, getmac, ping). Here's the exact line that gets executed: `netdom renamecomputer %COMPUTERNAME% /NewName:#{newname} /force` FYI, This is windows 7 x64

  • Ruby Metaprogramming

    - by VP
    I'm trying to write a DSL that allows me to do Policy.name do author "Foo" reviewed_by "Bar" end The following code can almost process it: class Policy include Singleton def self.method_missing(name,&block) puts name puts "#{yield}" end def self.author(name) puts name end def self.reviewed_by(name) puts name end end Defining my method as class methods (self.method_name) i can access it using the following syntax: Policy.name do Policy.author "Foo" Policy.reviewed_by "Bar" end If i remove the "self" from the method names, and try to use my desired syntax, then i receive an error "Method not Found" in the Main so it could not find my function until the module Kernel. Its ok, i understand the error. But how can i fix it? How can i fix my class to make it work with my desired syntax that?

  • Basic Ruby On Rails Linking Help

    - by dweebsonduty
    So I am beginning to work with Rails and I get some of the concepts but am stuck on an important one. Let's say I have customers which has many jobs and jobs which belongs to customers. How would I go about creating a new job for a customer? I can create a link that goes to customers/1/jobs/new and I can grab the customer ID but how do I tell it that I am creating a job for customer 1? I know this is the most basic of things but I just need a push in the right direction. This is my form so far: How do I get :customer_id to populate with the customer_id param? <h1>New job</h1> <% form_for(@job) do |f| %> <%= f.error_messages %> <p> <%= f.label :customer_id %><br /> <%= f.text_field :customer_id %> </p> <p> <%= f.label :manufacturer %><br /> <%= f.text_field :manufacturer %> </p> <p> <%= f.label :serial_number %><br /> <%= f.text_field :serial_number %> </p> <p> <%= f.label :problem %><br /> <%= f.text_area :problem %> </p> <p> <%= f.label :notes %><br /> <%= f.text_area :notes %> </p> <p> <%= f.label :status %><br /> <%= f.text_field :status %> </p> <p> <%= f.label :tech_id %><br /> <%= f.text_field :tech_id %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> <%= link_to 'Back', jobs_path %>

  • Basic Array Iteration in Ruby

    - by michaelmichael
    What's a better way to traverse an array while iterating through another array? For example, if I have two arrays like the following: names = [ "Rover", "Fido", "Lassie", "Calypso"] breeds = [ "Terrier", "Lhasa Apso", "Collie", "Bulldog"] Assuming the arrays correspond with one another - that is, Rover is a Terrier, Fido is a Lhasa Apso, etc. - I'd like to create a dog class, and a new dog object for each item: class Dog attr_reader :name, :breed def initialize(name, breed) @name = name @breed = breed end end I can iterate through names and breeds with the following: index = 0 names.each do |name| dog = Dog.new("#{name}", "#{breeds[index]}") index = index.next end However, I get the feeling that using the index variable is the wrong way to go about it. What would be a better way?

  • Passing parameters thru Ruby's OAuth

    - by JP
    I'm using Mirven's Twitter OAuth Sinatra example and trying to figure out how I can send a 'next page' parameter with the Oauth request: ie. The user attempts to visit /edit/profile which requires a login so I redirect to /request which deals with login via twitter - I now want to be able to redirect the user to the address they were originally looking for if they log in successfully. I thought I could do this in the .get_request_token line with this code: @request_token = @consumer.get_request_token({:oauth_callback => "http://#{request.host}/auth"},{:next => params['next'] || '/'}) But params has no additional items in the /auth handler. I'm new to OAuth, how would I go about doing this?
