Forgot to add other images... I'll embed them all, too.

Arch Decisions related to an Issue

mmh, very interesting plugin. And thanks for the detailed explanations of the underlying philosophy in your blog. I'll think about how it would integrate into our PM approach...

BTW, is there a way for categorizing (e.g. with a custom field) Factors such as requirements, objectives, risks, etc?

Looking forward to a 0.9x release...
Eric

Thanks!
I hope you end up using it. I find it very helpful.

There are several categorizations I'm considering doing. I have thought about that for Factors. Since they can be just about anything, the categorization would have to be pretty open-ended (as in, you should be able to create new categories on the spot, sort of like tags). One other complication is that some kinds of factors may already be stated somewhere in another way. A requirement, for example, could very well be an issue in Redmine, so there should be a link to it. Also, one decision may impact another ("We have decided to use JBoss, so using their ESB would be more compatible"), so in a sense, arch decisions become factors of their own. I'm mulling over the best way to handle that sort of thing. For now, you can just make the statement, then link to the item in the "Evidence" section.

Another thing that needs categorization is the ADs themselves. In my old place of work, I had two sets of orthogonal categorizations: functional component (which functionality does this most affect) and non-functional (which framework, layer, technology, etc.). It was very helpful for reporting, for finding ADs, and for taking a look at all the decisions related to a given topic. But in reality, a tag-based approach is the only one that makes sense. So look for tagging in the future.

And the last idea I'll mention here is the hierarchical nature of ADs. One big decision can lead to many more specific decisions that need to be made. Also, one decision can be deprecated in favor or another, or make another decision irrelelvant. So there will eventually be some sort of "Related ADs" field in the future as well.

But first, let's get it working with 9.2! :)

This looks superb!

Mixing high-level decisions with the nuts-and-bolts of day-to-day work never seems like the right thing to do, but there's not really a good way of avoiding that in Redmine as it is.

Very much looking forward to a trunk-compatible release :)

Cheers,
Chris

It took me all weekend (at least, all my late-night hours), but now you've got it. The latest release of the plugin is compatible with 0.9.2. For those still using 0.8.x, I created a separate branch ("redmine-0.8.4"). Now you've got no excuses not to try it! ;)

Hi,
I'm trying to install that plugin on a Redmine 0.9.1 (rails 2.2.3) but, when I type the command

rake db:migrate_plugin RAILS_ENV=prodction

you missed 'u' in production

Sorry, I checked one more time but it is a transcription error. the problem still continue.
Right command is:

Thank you

I've tried installing this plugin and it seems to work perfectly apart from one thing:

I have also question_plugin (https://projects.littlestreamsoftware.com/projects/redmine-questions) installed and after installing redmine_arch_decisions, there is an error while updating a project:

For some reason the question plugin starts looking for its templates in the arc_decision folder... Not sure why this could happen...

When I upgraded to 0.9.2, I was having problems with templates myself, and added a line to add the plugin's path to the mailer's view path.
Could you register this as a bug in the issue tracker? http://opensource.integritas.com.br/projects/redmine-ad/issues
I'll take care of it there ASAP.

I created an issue in the main issue tracker: http://opensource.integritas.com.br/issues/show/605
Please post your comments there.

Plugin installed its tables in database in latin1 charset instead of utf8. Yes, latin1 is default for redmine database but all other plugins have installed their tables in utf8.

i did not have a message from Public ITS with activation link on my e-mail (account Alexey Lustin)
thats why i write here:

1. feature request: - add statuses label of AD and Factors to i10n (<plugin_dir>/config/locales/en.yml)
2. i have attached ru.yml (0.1 version) to this comment

thanks for this plugin - very useful in IT Department

I have no idea what I'm doing wrong so if anybody could provide some suggestions that would be amazing :)

I'm not sure what to tell you here. I've seen similar errors, but not that exact one. What's really strange to me is the "not" in:

Object is not missing constant Project!

It looks like something made it think it couldn't find Project, which is a standard Redmine class, but then suddenly found it when it was trying to handle the error. I'll have to look in the source code to see what's up.

What's more, it looks like it was the Issue class, in it's act_as_attachable call, that failed. Some I'm somewhat at a loss. My first guess would be that there's something wrong with your Redmine installation in general.

• Were you able to migrate the main database using rake?
• Do you have any other plugins besides Arch Decisions installed? If so, which?
• What versions are you using of everything? Are all your gems up to date?

You might want to try deleting the Arch Decisions plugin, and running migrate_plugins again, just to see what happens.

I installed Redmine about a month ago and it migrated fine (after some initial issues). It seems that everything is running fine so far. I've created some projects, issues etc.

My install is: Redmine 0.9.3.stable (MySQL) on Windows 7 x64
Plugins (besides all the default Redmine stuff):
- Redmine Graphs plugin 0.1.0
- Redmine Hudson plugin 1.0.3.1

I've just tried removing Arch Decisions and running migrate_plugins and that works fine. The output is:

E:\webservers\railsapps\redmine>rake db:migrate_plugins

I'm guessing this also means that my gems are up to date, but I'm a total Ruby noob so there may well be something wrong.
Is there any other information that I can get that would help diagnosing the problem?

Hmm... looks good to me. Can you try reinstalling Arch Decisions, then running the following command?

rake rad:db:migrate

When I copy the Arch Decisions directory back to the vendor/plugins directory and run the rake rad:db:migrate command it still fails. The trace is:

• Invoke rad:db:migrate (first_time)
• Invoke environment (first_time)
• Execute environment
  rake aborted!

Could I be doing something wrong with the file copy? Or have I maybe gotten the wrong version from github? I just grabbed the latest version (I assume, I went to the github page and clicked the 'download source' button).

I don't think so. My guess is it's some sort of conflict with the other two plugins. Try renaming the module in /lib/arch_decisions_issue_patch.rb from IssuePatch to ArchDecisionsIssuePatch.

If that doesn't work, try temporarily removing the other two plugins you mentioned and see if that does it.

If I want to remove the other two plugins do I need to run a migrate for all the plugins or just arch. I don't really want to lose my settings etc.

If it's a conflict, it would just be with the Ruby code, not with the database. So you could just move those plugins to an outside folder, then move them back.
