Source/link? I fear they won't work exactly like the ones in 2.3 did, i.e. we still have to evaluate exactly what changes and how that affects us.

Sources: rails-engines site, the blog of Piotr Sarnacki, and I've got some bookmarks about the transition at home.

What's sure for now:
  • Rails 3.0 supports a kind of Engines, but there's no mechanism for migrations, nor copying assets automatically (nor overriding views iirc) ; for sure they're not useable in Redmine at this point
  • Rails 3.1 Engines will support these kind of things (needs to be precised I know), but all documentation I read on Rails3' engines makes me think that plugin developers would have to package their plugin as a gem
  • Redmine cannot support Rails 2.3.x and Rails 3.x at the same time :)

Indeed, Rails 3.1 RC is out and supports migrations as well as moutable apps, see http://weblog.rubyonrails.org/2011/5/22/rails-3-1-release-candidate.

Notes- :

Rails 3 applications include a Gemfile and support the use of Bundler (see http://weblog.rubyonrails.org/2010/8/29/rails-3-0-it-s-done).
Rails 3.1 default scripting lib is now jQuery instead of Prototype.

Is there any update on migrating to Rails 3.x? It's becoming a pain maintaining Redmine as it currently is. Upgrading to 3.0/3.1RC would definitely improve the development process.

I do understand that you are having trouble loosing compatibility to lots of good Redmine plugins, so I suggest you start Redmine + Rails 3.1RC development on a seperate branch and publish Redmine for both Rails versions in a transitional period (maybe 1 year?) giving all plugin developers time to migrate their plugins to a Rails Engine.

Any thoughts?

Updated by Etienne Massip almost 13 years ago

You should try to make it work straight with Rails 3.1 (rc4 is the last release) since (I guess) Redmine will never run with 3.0 due to the lack of engine support.

Moreover, you might detect and report some Rails 3.1 rc issues whic could be fixed before release time, making it easier to integrate with RM.

BTW, do you run Rails 3 RM with Ruby 1.9 ?

So, is there any official announcement regarding 3.x support? A plan? Redmine 2.0? I found nothing on Wiki. Is there anyone leading the efforts to this end?

Because I'd like to contribute to make Redmine Rails 3.x compatible. It's not clear if there's a branch for it. I guess any patch regarding this shouldn't go to master branch, isn't it? It seems Toshi is already doing some work on this. How could I be of help regarding this matter?

Second, don't you agree this is not the correct place for posting about these Rails 3.1's new features articles, like Etienne's?

Thank you.

If you run with current database of Redmine 1.2 on Rails 2.3.11,
you need to run "rake db:migrate".

In order to run tests,

As this is now Rails 3.1... and a lot of things will break in the upgrade anyway.

Would it be a good idea to change this to a mountable engine?
(or even a stranded engine so that users can upgrade by just changing the version in the Gemfile.)

I have experience and can help out if you go down this path.

CON: You may want to namespace everything so it plays nice with other mountable engines.

If by full engines you mean ones with there own logic/models/controllers/migrations that can be added by just adding something to your Gemfile.

Then yes, I use them where ever possible :)

Though I don't have all that much experience with mountable ones yet.. as 3.1 is still new and I don't really have any bread-n-butter projects in my day job that could use the functionality.

No, that's full engines vs. mountable apps. Mountable apps are self-contained and referenced only in the parent routes.rb to tell which "top-level" URI the mountable app has. Full engines are "nearer" to the 2.3 engines in that they are loaded with the main app, have access to all the same models, controllers, and everything (mountable apps are fully segregated). Both types are/can be packaged as gems though.

I think you can start with cloning and setting up test environment to see what doesn't work. Then if you manually tested all features and everything seems to work, you can run redmine tests and see if there are any failures. I there are no any, you're done.

Then you can think of how to enable users to use Redmine with both Rails 2 and Rails 3. As of now the work is done/coordinated by Toshi. Seems like every week he rebases his work on the latest revision from svn trunk. AFAIK, there are no any todo lists. But you can look into git/hg log. There are many commits marked as "TODO", so you can review these patches to see what's wrong with them.

Actions #42

Updated by Jean-Philippe Lang about 12 years ago

I have a working copy that runs and passes the full tests suite with Rails 3.1. There's some work to be done in order to provide the current features for Redmine plugins (migrations, view overriding, assets...) but still, most plugins won't be compatible out of the box. And honestly, I'm a bit disappointed with the performance. Redmine is 1.5x to 2x slower than with Rails 2.3. With ruby 1.9.3, it barely runs as fast as current trunk with Rails 2.3 + ruby 1.8.7.

Then you can think of how to enable users to use Redmine with both Rails 2 and Rails 3.

That's not really an option. There are too many changes in Rails 3 to support both versions with the same code base.

Did anybody find out how to get wiki working? I've got an error:

the problem is in the following line:

vendor/plugins/acts_as_versioned/lib/acts_as_versioned.rb

Somehow versioned_type column is missing.

Updated by John Yani about 12 years ago

Update:

Seems like it is because Redmine doesn't use rake tasks provided by acts_as_versioned: create_versioned_table and drop_versioned_table

So, I should add migration field for versioned_type myself

Here is the detailed explanation:
http://bibwild.wordpress.com/2011/07/12/more-thoughts-on-unbearably-slow-rails3/
Shortly, it is because of extra ruby garbage collection, caused by increased size of the call stack in Rails 3.

This is also one of the things I would like to see in Redmine 2.0. Upgrading to Rails 3 however does not imply that Redmine 2.0 will use JQuery. I personally doubt that this effort is also about migrating to JQuery.

If you are using Redmine as is it doesn't matter what framework is being used. But if you want to extend Redmine, it does. So for example I added functionality which uses a JQuery Slides (http://slidesjs.com/). Now my 'extended' Redmine installation uses JQuery and not Prototype for some pages. Using Prototype and JQuery in one website is of course not so nice but necessary because JQuery has a lot more to offer.

Whatever, Redmine has not Javascript API, jQuery and Prototype can coexist very well and I can't see why using 2 tooling frameworks would be bad.

Updated by Terence Mill almost 12 years ago

Hmm i hoped we will get rid of prototype because we wanna integrate our SSo Solution for redmine (which is based on CAS) and the problem with redirect on ajax request direct after an revelidation attempt of the SSO gatway (a java servlet filter in front of web.xml war of a jruby redmine tomcat installation), this redirect of an XMLHttpRequest (fired by prototyp.js i think) is not understood by the browser. This leads to "nothing happening" in the application as long a non ajax request is triggered by the request caused by user click.
Our SSO Gateway in front of the redmine can understand jquery ajax requests and wraps them so that the redirect in the browser works. This does not work for prototype js.

There is no documentation where and how often ajax is used in redmine forms, else we could think about moving this urls by filter out of the sso secure area and workawound the problem.
