I am just getting started with Radiant and am trying to use it as a Rails 3 engine. When I try to install an extension, I get an error about RAILS\_ROOT not being defined. This was easy enough to resolve (I added a RAILS\_ROOT constant in config/boot.rb of my app). However, the RADIANT\_ROOT constant is also undefined. Here is the stacktrace: mario:(git)strangeloop[radiant\_engine]/$ script/extension install forms /Users/mario/.rvm/gems/ruby-1.8.7-p302/bundler/gems/ radiant-1e7494558a8e/lib/radiant/extension/script.rb:286:in `extension_paths': uninitialized constant Radiant::Extension::Script::Util::RADIANT_ROOT (NameError) from /Users/mario/.rvm/gems/ruby-1.8.7-p302/bundler/gems/ radiant-1e7494558a8e/lib/radiant/extension/script.rb:278:in`installed?’ from /Users/mario/.rvm/gems/ruby-1.8.7-p302/bundler/gems/ radiant-1e7494558a8e/lib/radiant/extension/script.rb:304:in `initialize' from /Users/mario/.rvm/gems/ruby-1.8.7-p302/bundler/gems/ radiant-1e7494558a8e/lib/radiant/extension/script.rb:261:in`new’ from /Users/mario/.rvm/gems/ruby-1.8.7-p302/bundler/gems/ radiant-1e7494558a8e/lib/radiant/extension/script.rb:261:in `execute’ from script/extension:5 Since I am trying to use Radiant as a Rails engine, what should the RADIANT\_ROOT be?

The 0.9.1 gem is only compatible with Rails 2, but that’s the latest stable release. For hacking on the rails3 branch, I’ve been unpacking it into lib/radiant and pointing Bundler there with gem “radiant”, :path =\> “lib/radiant”. ---

Another data point is that if I try to run rake from bundler, I get: mario:(git)radiant[mario-rails3]/$ bundle exec rake -P (in /Users/mario/tmp/radiant/radiant) rake aborted! uninitialized constant Radiant /Users/mario/tmp/radiant/radiant/Rakefile:9:in `\’ (See full trace by running task with --trace) So it gets past the require ‘dataset/tasks’, but blows up on the line that says: Radiant::Application.load\_tasks –Mario ---

I’d like to do what you suggest and perhaps I am going about it the wrong way. I thought what you were suggesting below was creating a local gem build of the radiant rails3 branch and then unpacking that in a ‘lib/radiant’ directory within the project I am working in. Is that what you were suggesting or something different? I tried doing what I just described, and I got an error trying to run rake. Here’s what I did: mario:(git)radiant[mario-rails3]/$ rake -P | grep gem rake aborted! no such file to load – dataset/tasks /Users/mario/tmp/radiant/radiant/Rakefile:7 (See full trace by running task with --trace) I had a look in the Rakefile and saw that on line 7, it is trying to require ‘dataset/tasks’. There isn’t a dataset directory with a tasks.rb file anywhere that could find in the project. Do I need to have something else in place to have the rail3 branch working? I was hoping that all I needed to do was: rake radiant:gem and have the local branch built into a gem that I could unpack in my project (per your suggestion), but it seems that creating a gem from the branch isn’t working out of the box (unless there is another way to do it). –Mario ---

I think I have been bitten by this as well I’ve tried a rake production db:bootstrap which runs ok until trying to recreate the admin user in which I get: rake aborted! undefined method `home\_path’ for #User:0x6fe0ce3b4dd0 Doing some digging I found references to making sure there are routes in place, but this might be a red herring. I have the following versions of rails installed (3.0.3, 2.3.8, 2.3.5, 2.3.4, 2.3.3, 2.2.3, 2.2.2, 2.1.2, 2.1.1, 2.1.0, 2.0.5, 2.0.2) Looking at the reference to gemfile (which I am going to have to read up on) in Joshua’s previous mail I was wondering if it would be possible to fix the rails version to say 2.3.8? If so what else should I be aware of? I don’t think I can remove 3.0.3 as I’m not sure if it is in mine or from Dreamhost’s installation. Marc ---

You don’t need to build the gem. Just clone the rails3 branch into lib/radiant of your current project and load Radiant from there. My Gemfile looks like this: ``` gem 'rails', '3.0.1' gem 'sqlite3-ruby', :require => 'sqlite3' gem 'radiant', :path => 'lib/radiant' gem 'compass' ``` > Do I need to > have something else in place to have the rail3 branch working? A lot of the Rails 3 branch simply doesn’t work yet. That includes the rake tasks. As I said before, the Rails 3 conversion has just begun and I guarantee you’ll continue to run into problems. ---

That is good to know, and now means I have to work out why I am getting: undefined method `home\_path’ for #User:0x6fe0ce3b4dd0 when creating the admin user ---

I think the culprit was User Home. Disabled it and db:bootstrap happened, although some of the tables for extensions didn’t get created so the site is fragile at the moment Almost at the point of starting over with the hope that it works out better than the first time Marc ---
