To busy to complete…

So I’ve been getting a little busy at work lately, and while I’d like to really take you guys through a ToDo list tutorial, I just don’t have the time right now to work on that, while learning Rails 2.0, and then working on getting a ToDo list app working as well.  Rather than leave you guys high and dry without finishing this, I thought I’d show you this really cool open-source ToDo application that you can install for free!  Check to FooToDo here!! I think you guys will like it.  I’ve played around with this on my Development machine, but not in a Production setting.  From what I’ve been able to tell it looks like it’s no longer being updated (it’s running under an older version of Rails as well).

On other news, I would like to invite anyone in the NOVA/DC area that’s interested in hearing Chad Fowler and Rich Kilmer at the DCRUG meeting this Wednesday, March 26th. Here’s the details:

Todo list application with Rails 2.0!

I’ve recently taken a new position doing Rails applications full time (which I’m definitely excited about) however, between myself and the other developer, we’ve decided to go right up to Rails 2.0.2. This of course did not fit with me very well because I haven’t done rails development full time yet, and what rails apps I have done were in 1.2.6 and lower. I haven’t been a good developer because I wasn’t paying attention to all the new features and how they work. Of course I posted awhile back about some of the new updates here, but that’s about all I’ve done with Rails 2.0 until last week when I started my new job.

This is tutorial 1 of a new series I’m creating for making a simple CRM application that you can use for some of your daily tasks. Today we are going to create a simple todo list without writing any code (well to start off with). First create lets create a new app by typing,

rails -d mysql todo (I’m adding -d mysql, because sqlite3 is the default database and I’m using mysql)
cd rails

Next, we need to create our databases so we can type the following with rails 2.0.

rake db:create:all

Now that we’ve created our databases, it’s time to make our controller and model. For this, so that we don’t have to write any code, we’ll go ahead and scaffold this. We’ll type the following.

script/generate scaffold Todo title:string body:text done:boolean due:datetime

We can now migrate our database so we’ll type this.

rake db:migrate

Finally, all we have to do is start our server.

script/server

Then we can go to http://localhost:3000/todos and we’ll see our index page. You know have a working todo list, not very design oriented of course, but you are well on your way to making it yours. I’ve put up the application the way it should look here.

If you are looking for a version of this with pre-2.0 of Rails, you won’t be able to use the “rake db:create:all” command, so you’ll have to make your database another way. In the next tutorial we’ll add a customer database with a custom search so that we can search all your customers. Until next time folks!

New Ruby on Rails Host Makes Awesome Entrance!

Heroku is a new Y Combinator startup that joins the growing number of Ruby on Rails hosts, however this host adds a special step of using your browser to build your apps. You can now create Rails applications inside of your browser. Or if you prefer to use your development environment you can do that as well. Heroku is built using Amazon EC2 service. You have the option to upload your own apps via a tar file, or through their gem and git.

From their website they have an awesome list of features:

  • Instant Deployment
  • Create and Edit Online
  • Integrated Stack
  • Elastic Performance
  • Share and Collaborate
  • Import & Export
  • Full Ruby Environment
  • Gems & Plugins
  • Rails Console
  • Generate Code
  • Painless Migrations
  • Rake Console

But don’t take my word for it, check out their screencasts for more information on how to get things up and going.

Heroku, part of Y Combinator startups from this winter, has been in development since June 2006 and has attracted about 2500 users with around 2000 apps.

I do hope that we start to see some new features like support for subversion, mysql databases, and capistrano based deployment. I look forward to seeing what else comes from them. Please keep these guys in your rails radar.

I’ve got my account setup and played with it for a few hours today. If you would like to give it a try, they have a small waiting list, however if you send me an email I can work on sending you an invite faster. Feel free to send me an email at ajmorris2002[at]gmail.com for an invite.

Ruby on Rails Instructions Released for Leopard

Dan over at Hivelogic released an updated guide for installing Ruby, Rails Gems, Rails, and MySQL. Check out the article here. If there’s anything else that you need to install (like RSpec, Capistrano, SVN) you can do that with the following commands.

To install RSpec just type:

$ gem install rspec

To install Capistrano, type:

$ gem install capistrano

To install SVN it’s a little different, so you’ll have to install with the following command:

$ curl -O http://subversion.tigris.org/downloads/subversion-1.4.3.tar.gz
curl -O http://subversion.tigris.org/downloads/subversion-deps-1.4.3.tar.gz
tar xzvf subversion-1.4.3.tar.gz
tar xzvf subversion-deps-1.4.3.tar.gz
cd subversion-1.4.3
./configure –prefix=/usr/local –with-openssl –with-ssl with-zlib
make
sudo make install
Once you have everything is done you should be all set. If you want to check out any other gems, check out this site http://gems.rubyforge.org/gems/.
