Rails ActiveRecord::Base missing find_all_by_date_range
Hello everyone,
A current project I am working on required finding records within a certain date range. Many other projects I have worked on also required something similar. So, I decided to create a Rails gem to handle this. The gem is available on GitHub. http://github.com/timmatheson/find-all-by-date-range/tree/master
Install
Usage:
I hope this helps anyone else needing this feature of ActiveRecord::Base.

Rails JavaScript and CSS file AutoInclude Snippet
Ok so you have a Rails application and it’s growing fast. Your putting complex logic where it belongs, Your partials are DRY, and your using TDD and BDD concepts in your project. The world is yours, your code is bullet poof. Well what about those pesky JavaScript and CSS files? If you have a lot of them they can easily get out of hand and become redundant and duplication becomes a direct result. So how can you DRY it up a bit you ask? With an asset_autoinclude_tag helper. The concept is simple. For each controller/view in your app you design a javascript and or css file with code directly related to the pages rendered by them. In addition to this you name them using the same Rails naming convention as your other files. For instance you have a PublicController you would create a public.css and or public.js file for any css/js code related to that controller. Everything else can go into application.js and application.css.
Heres the code.
Update:
I have moved this into a gem if you would like to use it in your projects. It’s available in my GitHub repository.
git clone git://github.com/timmatheson/asset_autoinclude_helper.git
You can also install the gem by adding GitHub to your gem sources and installing it.
INSTALLATION gem sources -a http://gems.github.com sudo gem install timmatheson-asset_autoinclude_helper-0.1.0
Then to include it in your application just call it in your global layout like this.
<%= asset_autoinclude_tag %>
You can also pass in options for the javascript_include_tag like :cache => true
<%= asset_autoinclude_tag(:cache => true) %>
And thats it. I hope this helps you dry up your code a bit. I know I am probably not the first one to think of this. I plan to make it into a gem soon so check back.
Best regards,

Refactoring ruby code
I am currently working on a Rails project with a team of developers.
I did some refactoring of a helper method and thought I would share it with the world.
Maybe someone out there can benefit from this.
NOTICE: I changed the helper method name and the model[attribute] values to show a more generic method.
Before refactoring
def some_helper_method
select_tag 'model[attribute]‘,
options_for_select([[" Today ... ", Date.today], Date.today+1,
Date.today+2, Date.today+3, Date.today+4, Date.today+5,
Date.today+6, Date.today+7])
end
After refactoring
def ship_date_select(model,attribute)
todays_date = Date.today
options = [['Today ... ', todays_date]]
6.times do |x|
options << todays_date+x
end
select_tag "#{model}[#{attribute}]", options_for_select(options)
end
The problem with the first example is that it is not very DRY. It is asking Ruby the date 7 times.
It should only need to ask this once and store it in a variable called todays_date. If anyone out there knows a better way to do this please feel free to shoot me an email.
Best,
Tim M.

Holistic Dog Food - Better for your dog
Hello everyone,
I have recently switched my dog over to holistic dog food products to see if it makes any difference at all and it does. Domino has been on holistic dog foods for about 2 months now and his coat is nice and soft and very shiny, his teeth seem to be whiter and he has not been chewing up my things as much lately. I get my holistic dog food from work as I work for a pet store in Kenosha WI. The reason I wanted to let everyone know this is I didn’t think it would make that big of a difference. Yet it did after only a few weeks. If you wanna see the difference you can buy holistic pet food for both dogs and cats by clicking the link below.

DIY Desktop Virtual Reality Display on the cheap (Nintendo WII Only)
Johnny Lee, and his WIImote hacking tips has created a way to make 3D games (for the WII) a reality using DIY IR glasses. This is a really cool concept, the software tracks the movement of your head and adjusts the current display accordingly. I am definitely going to experiment with this technology.

1 Year of Ruby on Rails Programming
Over the past year I have made the change to Ruby on Rails as my programming language and framework of choice. The reason is simple, Ruby on Rails manages enough of the tedious tasks faced by most developers fairly easy. With that said it is also safe to say it makes me more productive, and increases the quality of my work. The pros outweigh the cons by far. I would encourage anyone programming in PHP, ASP/ASP .NET, C+, C++, JAVA, or even Cold Fusion to give Ruby on Rails a shot. Most likely you will hit the Rails and never look back, yeah it’s that great. It has now been one year since I originally Installed Ruby, Installed Rails and dug deep into the code. While I am still learning a great deal about some of Ruby’s more advanced functionality I have mastered for the most part the entire framework from unit testing to model associations. If you are just getting started in Ruby I would be glad to answer some of your questions, simply send me an email or comment on this post below.

SSH Copy files from one server to another using rsync clie tool
Ok so you have a file and want to move it to another server on another network. What to do what to do. Well you could just FTP it to your local machine then FTP it up to the new server, but this file is 300mb and that would take a long time. Being the lazy programmer you are you may seek another more ‘geek friendly’ way of doing this. There is a tool called rsync that does just that. It will login to one server, shake hands and then begin transferring your data to the specified new directory. I tested this on BlueHost and no dice. Authentication failed however I am sure if you have time to try and configure the two machines to talk you could do it. This would be great if you had root access to both machines. In my case I only have root to the destination server and not the source server. BlueHost technical support said that the port rsync uses is blocked. Im not sure what that port is but if you found out you could configure rsync as a daemon service and bind it to that port. I will be looking into this in the future and posting more about it in a follow up post.
Happy tunneling.
rsync -av -e ssh username@oldserverhost:/home/old_home/ /home/new_home/
This command was gracefully copied from [Tony Spencer's Website] it’s a great website I highly recomend it if you like my site (even has the same ndesign Word Press theme as my blog).
New Ruby on Rails site

Surface computing brings multi touch sensors to your home
I have been following this multi-touch sensor based computer technology pretty closely. I am fascinated by the thought of these types of devices to replace our current constraint prone desktop and laptop computers. The file transfer feature has got to be one of the coolest features of the coffee table computer shown in the video. I dream of a day when wads of cables become non-existent.
Send emails with ease, Rails Mailers Demystified
Setting up a mailer in Rails can seem like a daunting task, especially to new comers. I found this video and several other resources online to be very helpful in explaining the ins and outs of setting one up. This is a very in depth video explaining how mailers can make life easier for the Ruby programmer. See the screencast!

Use Hibernate and Standby to Conserve Batteries
Microsoft has a great article on how to conserve your laptops battery supply using hibernate features available in “most” windows installations. I really think this is an overlooked feature available to Microsoft customers. Read the full article
- Open Power Options in Control Panel. (Click Start, click Control Panel, and then double-click Power Options.)
- Click the Hibernate tab, select the Enable hibernate support check box, and then click Apply.
- If the Hibernate tab is unavailable, your computer does not support this feature.
