an illustrative guide to master the spree e-commerce

i am newbie to spree e-commerce, after reading many queries & answers i understood that using spree is not easy for our custom needs of e-commerce sites. anyhow, is there any illustrative guide ( other than spree official guide) /tutorial to learn & use the spree e-commerce effectively ? plz., inform
Unfortunately, you're correc tin that Spree is not "easy." This is because Spree was made "by developers for developers." If you don't have an extensive knowledge of rails, or want a ecommerce solution that doesn't require much coding, Spree is certainly not for you.

Learning Rails, workshop, course, resources

Trying to learn rails, but the beast is quite complex for a beginner :)

I know this doesn't directly answer you current question but I found that the Ruby On Rails Tutorial by Michael Hartl really helped me.

backbone on rails with persistence

I have an app that I'm building and would like to implement rails persistence to the backbone front end.
can someone point me to a simple repo or tutorial where i can learn about the configuration needed in rails to be able to persist data.
Thanks
I suggest to take a look at the backbone-rails gem.
It also provides a backbone:scaffold generator (I find that many rails generators can be used like "tutorial").

Rails 3: A/B Testing App Features

What's the best way of AB Testing new features and keeping track of the results?

There's a gem called Vanity which is designed for A/B testing in Rails (and appears to work in Rails 3).
Here's a tutorial on Vanity.
I've just released a gem that integrates the Google Analytics Experiments API with Rails. It is pretty full-featured and the reporting is right in Google Analytics. It uses a bandit algorithm, allows you to specify a subset of the audience to test and more.

I've personally used split and I've found it to be quite nice, especially with respect to the dashboard it provides for you.

Forum solution for Rails 3 and Devise?

I'm looking for a forum solution for a website I'm building. I'm using Devise and Rails 3, so does there exist any pluggable solutions?
What about 3rd party services?
The goal of Community, is to provide a simple, and easy to setup forum application without having to dictate how your site it setup.

You could build one yourself, you'll be surprised that it's not that time consuming, and you won't have to deal with the bloat that 3rd party solutions might come with. Here is a good place to start.
Savage Beast, Altered Beast and rBoard may be good starting points, but note that they are only for Rails 2.x afaics.
Note: rBoard has a Rails 3 branch but I have no idea how stable that is.
