I’ve never been a fan of using rake to download EdgeRails. To me it never seemed to make sense that you would make a Rails project generated by one version and then download the Edge version into the plugins directory. So with that in mind I’m going to tell you how I roll out EdgeRails projects and in turn show you how to download Rails 2.0RC1 and generate a project with it.
Before I get into it though, I’m expecting that you have a development environment already running. I expect that you already have rake, ruby, rails, svn, and all that other stuff installed. If you don’t, please see one of the thousand Internet posts on how to do that or the many chapters in books that cover it. Okay, now that we are on the same page – let’s get moving.Let’s open up your command line terminal. Go into wherever you create your projects in Rails and make a new directory for your new project:
mkdir -p new_project/vendor
The -p variable creates both the new_project directory and the vendor directory inside it (depends of course on your OS, you could always just create both manually). Go into the directory:
Now, run SVN and checkout 2.0RC1 into the vendor/rails directory.
svn co http://dev.rubyonrails.org/svn/rails/tags/rel_2-0-0_RC1 vendor/rails
Now from the project directory (new_project) run the rails script within the vendor directory.
ruby vendor/rails/railties/bin/rails .
That will execute the rails script on the current directory. You basically just did the same thing as executing “rails new_project”. That’s it, you’ve now checked out Rails 2.0RC1 and created the base project. Now get started…Have fun.
This morning (November 29th) the Rails team has released RC2 so if you are wanting to check out RC2 – use the svn checkout command of:
svn co http://dev.rubyonrails.org/svn/rails/tags/rel_2-0-0_RC2 vendor/rails
