Ruby On Rails - Myspace app development - ruby-on-rails

Which gem or plugin should I use for building Myspace applications using Ruby on Rails?

MySpace provides a REST API Ruby Library:
http://developer.myspace.com/community/libs/ruby.aspx
I don't know if it's any good.

There's also a Spacer gem. I wasn't able to get it working, however.

Here's a snippet of code for the OAUTH gem:

I was unable to get it working.

Another snippit of code for the OAUTH gem:

Also unable to get it working.

A large part of developing on myspace must be done through the REST api that myspace provides, as well as ajax calls to import the response. Unfortunately you're not allowed to use an iFrame until OpenSocial 0.9 which wont be out for a while. Until then become familiar with MySpace's API and ajax.

You can use the myspace-ruby-sdk http://code.google.com/p/myspaceid-ruby-sdk/

Is it possible to use piwik with Rails 4.2 and postgres

I am looking for an open source web analytic for my Rails 4.2 app, so after some research I found that piwik fit my needs. can I use "piwik" with postgresql ? it seems that they only support mysql but I am not sure if it still true at this moment!
also I've found a post about how to integrate it within Rails here but they use piwik_analytics which is a Gem for Ruby on Rails 3.x and may not work with 4.2 !
All the information I've found are a little outdated and I am not sure if there is a way to make it work with my current requirements. any help please ?
Piwik supports only MySQL, that's true
You don't need any gem because Piwik just needs to load some Javascript that needs to be embedded into your layout/views. The Rails app doesn't directly interact with it, only your visitors' browser. Which also means that it shouldn't matter whether it supports Postgres because it will most likely run on another machine as your Rails app.
Edit:
Regarding the gem you mentioned: I looked at it, too, when adding Piwik analytics to my app, but in the end went with writing the few required lines of JS myself.

Setting up ruby on rails gem ga_events

I am relatively new to web dev and I am trying to set up the ruby on rails gem ga_events (https://github.com/Nix-wie-weg/ga_events). I am doing this because I need to have google analytics event tracking within controllers and this gem seems like a good way to do it. The issue I am having is where the readme says, "After requiring ga_events.js, you have to choose an adapter." I am using Google Universal Analytics and thus I would like to choose that one. It doesn't say specifically how to do this. Where do I put that code block (https://github.com/Nix-wie-weg/ga_events#google-universal-analytics-analyticsjs)? Do I need to make a new file somewhere?
I'm assuming it's obvious for a more experienced developer. More detailed instructions+explanation would be really helpful. Thanks.
I'm using Rails 4.0.13 and Ruby 2.0.0p643.
I was having the same issue here! Turns out, it is just javascript code.
I put mine under application.js since it's a code that need to be on every page.

Old version of recaptcha get displayed instead of the newer version using the rails gem "Recaptcha"

Thanks to the gem https://github.com/ambethia/recaptcha/ (version 0.3.6), I managed to integrate Google Recaptcha into my rails app. The problem is that only the old version (V1) is displayed, similar to below.
However, I would prefer to the newer version with the checkbox like below, which is much easier for the users. Any idea how to get there?
There is some discussion about this, see: https://github.com/ambethia/recaptcha/issues/112
You are free to implement the new API by yourself it's not that hard actually, and if you have the knowledge submit a pull request to the original repository with a working solution :-)
The instructions on how to implement reCaptcha can be found here: http://www.google.com/recaptcha/intro/index.html

Rails 3 / PhoneGap: Converting a Rails app into an Phonegap iOS app?

I have a site built on top of Rails. In essence, I want to release a lightweight version of it for the appstore, and I think Phonegap is a good solution w/o writing a full iOS application.
What would be the easiest way to get something like this out of the door? I'm new to PhoneGap and would love if an experience dev could shed some light on how with is done. I feel it would also be a valuable resource for many other Rails devs.
My rails 3 app uses devise for authenication, carrierwave for file processing, amazon S3 for storage, and Heroku for hosting. Can someone give me some basic insight into how all these components are wrapped up and ablwe to be used with PhoneGap?
I'm new to Phonegap too, but I'm exploring the same idea than you and I've found this useful screencast: "PhoneGap + Rails 3 API"
http://vimeo.com/18763953
The idea is that you make an HTML5 client side app that makes calls to a Rails API on the server side.
Here is the code of the screencast demo:
https://github.com/quickleft/kbomb_phonegap_server (Rails API)
https://github.com/quickleft/kbomb_phonegap_client (HTML5 client with
Phonegap).
Hope it helps!
I think it could be relevant to check my phonegap-rails gem gem and my example rails / ember.js App that is exported with Phonegap. It also implements token authentication based on ember-auth and several OAuth strategies on top of Devise.
Currently in de the devel branch: https://github.com/joscas/base_app/tree/devel
Heroku deploy: https://starter-app-staging.herokuapp.com (the desktop version)
The gem exports assets, fixes paths etc. to allow seamless export of single page apps based on a rails backend.
At 37 Signals they rendered their html SERVER SIDE and just created an app wrapper. Here's the article: https://signalvnoise.com/posts/3743-hybrid-sweet-spot-native-navigation-web-content
This is an important difference in most approaches as most will re-develop their front end using a client side framework and it has the potential to save users a bunch of time. The downside is that I've heard rumors you can't get into the iOS app store, but it doesn't seem like they had a problem with it. There's also services like GoNative.io that will wrap your app for you.

What's the best gem to develop a Facebook Canvas/iFrame App (Rails 3.1.1, Ruby 1.9.2)?

I want to built a facebook canvas iFrame App. I tried to use facebooker but it does not work with rails 3. Can anybody suggest what gem I should use? If possible, please also provide a reference to a tutorial that can help me get started.
I would recommend fb_graph gem. The sample app code can be found at https://github.com/nov/fb_graph_sample.
