I am considering implementing a Facebook-integration to my web app. I want to be able to import friends names, their ages and their interests/likes.
A. First off, is this possible? Can I access this information?
This import will, more or less, be a one-time import.
I also want to be able to use Facebook-login and to use it parallell to my "normal" login (auth) functionality. I assume this should be quite straightforward since most websites have it this way (e.g. Fiverr.com).
B. These two things being my basic needs of my Facebook-integration, which gem would you recommend me to use?
C. I am 1 1/2 years into RoR and consider myself decent at Rails-programming but hardly know any JavaScript and very little jQuery. Will this integration be very difficult for me, you think?
Receommendations of useful blog posts etc will also be appreciated!
A. Check facebook doc on permissions. I'd say you can get a user friends list (id and names), but nothing more : the friends would have to allow your app in order for you to retrieve their data. I've stumbled upon this issue a few weeks ago, but we were retrieving albums and pictures. The data you want is less sensitive, so maybe you can do it anyway. Bottom line : check.
B. I'd suggest using devise for managing everything related to authentication. It is a well known gem, used by many and more. You can add support for facebook via omniauth; there's a wiki page on devise about how to achieve this.
C. Once you get your grasp around the OAuth concepts, you'll be good. You can use facebook connect without javascript/jQuery. Some features though, as the "like button", will require to use the js SDK. Besides these ones, you can do pretty much everything server-side. For more advanced queries, the koala gem can do that.
Hope this is enough for you.

I'm still learning rails but want to be sure I'm heading in the right direction. For several of my models I want to let a list of users know that updates have been made when a new record is created for example. I'd like to tie this to an email and in-app notification(doesn't need to be AJAX), next page refresh is fine.
I've been reading up on observers some and I think that's what I want but they seem somewhat controversial based on the blogs I've read. Services like Pusher seem to be overkill for my needs.
Would this be a good solution for this scenario? Also, can anyone point me to some example code that I could emulate?
Thanks!
Check out Rails Cast if you are trying to learn. Best free code base I have seen. Also check out this book another great learning tool. Agile Web Development with Rails (2nd edition).There might be some newer ones out but I have not checked.
I'm trying to create a rails app that fetches album scores from PitchforkMedia.com
For example, I want to grab the score 8.0 from this album as shown below in the image.
In my brief research, I came across a similar question asked from asp.net point of view.
Generally, the answers suggested
using http request
parse the HTML source
identifying unique flags around the variable score
Some answers came with use of built in asp.net functions.
Are there equivalent functions available in Ruby or Ruby on Rails?
Or can someone suggest some other way doing what I want to do?
Any suggestion will be appreciated. Thank you.
Edit 1: This is completely for personal use and education. Assume that there is no legal ramification for data mining from websites.
I would use Mechanize to scrape the content that you are interested in. Ryan Bates has a great screencast on how to use Mechanize.
You need to make sure you're reading the site's terms of use before you start screen-scraping data, especially if it's not for personal use.
This is a portion of Pitchfork's terms of use, and most other sites have something similar.
"Any reproduction, copying or redistribution of the Materials or design elements of the Website for any purpose are strictly prohibited without the express written consent of Pitchfork or its owner if Pitchfork is not the owner."
Screen scraping definitely falls in this category.
This might be a nonsensical question, but I have this task to create a rails app that shares session information, specifically login/authorization info, with an installation of a phpBB that some other person has customized to be more than just a BB.
Basically I need to rely on the user's phpBB login to authorize access to the rails app. I really don't want to have the user maintain two logins to use this conceptual single app.
I read a lot of documentation on phpBB and didn't find anything like exposed services or an API, but I'm hoping I just missed something obvious.
I've been considering adding a method to expose some hash or something to link the two applications rather than try to squeeze possibly different implementations of session.
Quick context, this work needs to be done fast and cleanly and I've never developed in php and rails is super fast so I am investigating the idea of integrating the two sides.
I might be off in the weeds, so don't be afraid to say so :)
thanks!
Have you checked phpbb-auth?

My site requires authentication, so it has membership. I wonder if I should create my own comment system for user to discuss/comment on an article, or should just use third-party comment system like Disqus or Intense Debate, which requires seperate account (Twitter, Facebook, etc.).
In fact, it would be good if there is a guide to create my own comment system or Q&A system for users to discuss a particular article on my website. If you know of any, please lemme know.
Thanks.
I recently am working on a project where I had to weigh the same things. I eventually decided to roll my own comments.
Namely the advantage of rolling your own is that you have full control on how they work. I needed a moderation system/queue that I needed to work a specific way, for one. Second, someday I will be looking to integrate a 'community reputation' system, so that was another plus for rolling my own. Such things I don't want to leave to a third party solution outside of my control and the third parties don't always have such a flexible API to modify.
On the other hand, Disqus (or similar third party commenting systems) may be up your alley if your needs are more simple. For one, it's easy to get up and running and may be all you may really need. Accounts for it work across anything using Disqus, and that may win convenience points for your users who are sick and tired of having to sign up for a million accounts for a million websites. Disqus also has built in tools (for spam, trolls, etc) and that is also convenient.
If you go with rolling your own solution with user accounts, you can integrate things like Facebook/Twitter/etc login to make the registration process easier. But overall, like I said, depends on how fancy or complex you need the whole thing to be.
Should you roll your own, a good start is a recent Railscasts episode on the Ancestry gem http://railscasts.com/episodes/262-trees-with-ancestry, it should give you a good start on building threaded comments.
Something in the middle :) Use the acts_as_commentable plugin :

I'm looking to build an application that handles authentication and authorization for a variety of smaller apps that may or may not be rails applications (e.g. some with sinatra, some with non-ruby frameworks, etc). These applications will be on separate domains.
Can I do this with Authlogic? I do not want to setup a rails application for each application, just use a central authenticator. I'm sure as I start reading and working the answer would become evident, but I'm trying to avoid a dead end (doing work and research, then finding out this can't be done.)
From what I've read this is a use case, and I'm looking for input from people who've done similar. This is at the idea stage so if i can offer more detail, let me know.
I think you are planning to build a cross domain, single sign-on service. Besides building your own, there are a quite a few project that do this out of the box.
rubycas is one of them : http://code.google.com/p/rubycas-server/
You could also look into open Id (http://openid.net), where the login functionality is done by a third party authentication server.
In case you want to roll your own:
It doesn't really matter which authentication plugin/system you will use. (I would choose devise/warden, but Authlogic will do just fine). Instead you need to focus on understanding the security problems and the http interaction between your service, the browser and the application for which authentication is used. I think it's doable, but you need to know what you are doing.
Today, the cool kids use warden, or the railsy thingy devise.
Im not sure but i think you cant use authlogic with a non-ruby-app.
I would probably go with Devise as well but you should look into some plugins for it like JanRain's Engage (used to be RPX Now). It allows you to use quite a few social login options (Facebook, Twitter, etc.) http://www.janrain.com/products/engage.
Ryan Bates from Railscasts.com just posted an episode on Devise using Engage this morning. http://railscasts.com/episodes/233-engage-with-devise
There are some more episodes about Devise on Railscasts too. http://railscasts.com/episodes?search=devise
If I were you I wouldn't reinvent the wheel. I'd use a third party service to authenticate and just get on with the project. Social connectors such as Engage will provide this functionality for you without all the time and expertise.
