Installing HoboFields Pre-Release for Rails 3

[Steve]

Hello,

I'm trying to install the latest pre-release version of HoboFields,
which supports Rails 3 (RubyGems doesn't have the latest code). I've
followed the steps on the relevant Hobo blog post (http://
hobocentral.net/blog/2010/08/24/hobofields-and-rails-3/), but when I
execute "rake install", I get the following error:

rake aborted!
Don't know how to build task 'install'

Can anyone help me with this? How can I successfully install the
latest pre-release version of HoboFields so that it will work with
Rails 3?

Note: I'm trying to use HoboFields, not Hobo. The latter I've
installed successfully, but I'd like to use just HoboFields.

Thanks,
Steve

Hi Steve,
try this:

gem list hobo_fields --pre -r

You can install the pre25, that - for hobo_fields - should be exctly the same in rails3 branch.

gem install hobo_fields --pre

Dear Domizio,

Thanks! Now, when I execute "rails generate", the HoboFields
generators are listed. However, when I try to create a model (e.g.
"rails generate hobo:model book name:string description:text"), I get
the following error:

/Library/Ruby/Gems/1.8/gems/hobo_support-1.3.0.pre25/lib/generators/

I've added "gem 'hobo_fields', '1.3.0.pre25'" to the project's
Gemfile.

Any ideas what might be causing this error?

Thanks,
Steve

There is probably a missing require in the model generator.
require 'generators/hobo_support/eval_template' which is invoked if you use hobo, but it is not when you use just hobo_fields.

I have just pushed it, so you should use rails3 edge if you want to try it.

Dear Domizio,

OK, thanks! By changing the source code of the installed gem as per
your information, it is now working perfectly!

However—it's probably a noob question—how do I use the latest "rails 3
edge" version that you've pushed? Do I have to check it out of Github,
build it, and then manually install it, or is there some other way to
do it...?

Thanks,
Steve

you can probably use the gem declaration in the Gemfile so it will use the git repo or a local installedd copy.
