Something like Spree for Grails? - grails

Is there something like Spree (Rails) for Grails? I've seen the answers on this question https://stackoverflow.com/questions/6543129/grails-ecommerce-framework-platform but it is more than half a year old and didn't give an answer that is similar to Spree.

Well, there is a new plugin based on Broadleaf Commerce. Wich is an open source Java eCommerce platform based on the Spring Framework...
http://grails.org/plugin/broadleaf

Please check out Greenfield. http://opengreenfield.org/. Built on the Grails framework.

How do I update an existing older rails project to a newer version

I have a Rails project using rails 3.0.7.
I want to update it to 3.1.0.rc6.
However the directory structure of these are really different,
is there an automatic way to transfer the directory structure? Thank you very much.
I'm not aware of an automated way to update Rails apps to 3.1, but I found David Rice's blog entry about to be a pretty good overview of the steps involved. You can find the overview at: http://davidjrice.co.uk/2011/05/25/how-to-upgrade-a-rails-application-to-version-3-1-0.html
I created a github project to track the difference of the default generated project layout of rails

Grails: How to make jQuery-UI work correctly with all its functions?

Hey I just installed jQuery-UI via grails install-plugin jquery-ui
And I can't make it work.
I read on the Grails Plugin documentation that I needed to update the file jQueryUiGrailsPlugin.groovy and change the JQUERYUI_VERSION to the most recent one. I went to change it and it had my same version, so now I don't know what it could be.
Any help would be greatly appreciated.
Stackoverflow is a poor place to ask questions of a new plugin like this one. You'll have much more success asking on the Grails User mailing list since the plugin authors are active there and can quickly answer your questions, and other users will benefit from the discussion.

tips for a open id authentication wrapper for rails

i'm looking for a rails plugin for open id authentication.
I'm using restful-authentication
Can you tip me any plugin?
Do you know any tutorials for using these plugins?
thanks
Use the open_id_authentication plugin maintain by Rails core team http://github.com/rails/open_id_authentication
When I tried this a few years ago, I had problems configuring Apache/mongrel. I vaguely remember with respect to Yahoo.
The plugin itself was easy to use!

Good code sample in rails

I have been developing in rails for the past 1.5 years .. however , I feel my code is not upto the mark , and I still dont fully utilize all that Ruby and Rails have to offer .
I have gone through all the material that is available on the guide site , and have incorporated that in my code . However , every time I see someone else's code , I find out new things about the language like idiomatic syntax etc . I was wondering if there are some really good code samples of rails that people can refer which would help me speed up my progress in rails . It can be anything , like some open source plugin or a app that has really high code standards .
You can start from GitHub. There are tons of Rails plugins and apps available.
Here's just a few examples:
GemCutter
Spree
Fat Free CMS
Insoshi
Plugin authors
Thoughtbot

My favorite and commonly used gem/ Rails plugin is will_paginate. Pagination is pretty common in any web applications.
will_paginate is hosted on GitHub. It works as a standard gem.
If you want to learn about Rails plugin development including how to read the code, you might want to read Plugin Patterns in Rails 2.

Are there any good googlemaps plugins for rails?

There are some good geocoding plugins (e.g. geokit) but can you recommend a googlemaps plugin for "the view" in rails?
I used YM4R/GM before but I don't know if its still up to date...
I've always just used GeoKit for all things GoogleMaps... it's a little old, but all the source code for "Beginning Google Maps Applications with Rails" is available at http://googlemapsbook.com/source/. It should walk you through pretty well on how to write the code for the front end. Advanced Rails Recipes also has some great code recipes on building geocoded points into GoogleMaps.
Looking on Github I found google_maps plugin. I haven't tried it but it seems ok.
