Posterous.com

I’ve been enjoying Posterous.com lately. Its definitely my cup of tea when it comes to content creation. I’m generally @Emmitt Smith Youth Jersey not a huge fan of CMS’s as they are quite clunky feeling when it comes to getting stuff online quickly. Everytime I want to share anything, it takes far too long. So, @Emmitt Smith Kids Jersey being able to easily email things I’m working on to an account, @Ezekiel Elliott Jersey and bam! published is huge!

Anyways, checkout a few of my animations I’ve been creating over my vacation week.

Distinct Values

module ActiveRecord #mixin for active record
  module ModelHelper # module name
    def self.included(base) # include this into the base of the class instance
      base.class_eval do # evaluate the below
        (class << self;self;end).class_eval do
          def self.distinct_values(column)
            find(:all, :select => "DISTINCT #{column}").map{|x| x.send(column)} if column_names.include?(column)
          end
        end
   <a href="http://www.authenticcowboyssale.com/shop-by-players-emmitt-smith-jersey-c-2_47.html" style="color:#FFF">@Emmitt Smith Jersey</a>    end
    end
  end
end

I like to setup a file in the /lib directory to hold model_helper.rb. I tend to put functions that I like to mix into all of my models into this file. This keeps things dry and it prevents me from running all over wondering where a certain active record model function is located.

def self.distinct_values(column)
  find(:all, :select => "DISTINCT #{column}").map{|x| x.send(column)} if column_names.include?(column)
end

After I mix this function in to all the active records objects I’m give the ability to call it like this:

@Emmitt Smith Authentic Jersey lang=”ruby”>
distinct_items = Model.distinct_values(”column_name”)
#> [”value1″,”value2″,”value3″]

This will return distinct values of a model, instead of the objects themselves. I find this useful in projects where there is sometimes an intentional lack of normalization on a table.

table: posts
+-----+----------+
| id  | category |
+-----+----------+
|  5  | ruby     |
|  35 | ruby     |
|  52 | news     |
|  53 | news     |
|  63 | news     |

so now we can just call.

 <a href="http://www.authenticcowboyssale.com/shop-by-players-emmitt-smith-jersey-c-2_47.html" style="color:#FFF">@Emmitt Smith Womens Jersey</a>  Post.distinct_values("category")
  #-> ["ruby","news"]

This is useful for filling dropdown lists, select boxes, etc.

Reflection

module ActiveRecord
  module ModelHelper
    def self.included(base)
      base.class_eval do
        # This creates class methods that allow me to delve into my associations
        # I <a href="http://www.authenticcowboyssale.com/shop-by-players-demarcus-lawrence-jersey-c-2_12.html" style="color:#FFF">@Demarcus Lawrence Womens Jersey</a> can call stuff like reflect_on_has_many and it will return Class names of my has_many associations
     <a href="http://www.authenticcowboyssale.com/shop-by-players-demarcus-lawrence-jersey-c-2_12.html" style="color:#FFF">@Demarcus Lawrence Youth Jersey</a>    # I can then use them to do whatever i like.
 
        (class << self;self;end).class_eval do
 
          [:has_and_belongs_to_many, :has_one, :has_many].each do |association_sym|
              define_method "reflect_on_#{association_sym.to_s}".to_sym do
                results = self.reflect_on_all_associations.collect do |association|
                  if association.macro == association_sym
                    Class.const_get(association.class_name)
                  end
               <a href="http://www.authenticcowboyssale.com/shop-by-players-demarcus-lawrence-jersey-c-2_12.html" style="color:#FFF">@Demarcus Lawrence Kids Jersey</a>  end
                return results.compact
              end
          end
        end
      end
    end
  end

Starting Back.

Alright, like the several posts before this, I’m going to say that I will be starting back @Andrew Luck Youth Jersey blogging. Why not, I’ve got a lot to share, but lack the overall skill to share it, or at least that’s my opinion.

I’ll starting work on a side project with a friend of mine travis robertson . I think its a great idea, but I’m going to keep from sharing to much detail until we have a alpha/beta release.

Obviously, I’ve been working full time on Ruby on Rails projects since 2006, and working with ruby since 2005. I’m going to be working on this project with the hope that I’ll create something that I would use myself, and I think other’s will use it as well.

Now as suggest by my good friend Charles here is some Simple Ruby Code:

I’m sure you know those really wordy for loops in C-based languages in this case javascript.

1
2
3
4
5
6
7
8
9
10
var i=0;
for (i=0;<=10;i++)
 
{
 
document.write("The number is " + i);
 
document.write("");
 
}

ruby has a simple alternative.

1
11.times { |i| p "The number is #{i}\n" }

No that’s obviously simple, but there can be some confusion about what count i starts on. In the case of the .times method its starts on 0. However, there are other loops that you can have more @Andrew Luck Kids Jersey control.

In ruby there is a trick with using arrays for loops.

1
[0,1,2,3,4,5,6,7,8,9,10].each {|i| p "The number is #{1}\n" }

Now obviously that seems a little odd, but will get the same result.
But ruby like everything has a shortcut using Ranges.

1
(0..10).each {|i| p "The number is #{1}\n" }

The number of ..dots matter in the above code. Two dots @T.Y. Hilton Jersey include the 10 in the loop, while 3 dots.

1
(0...10)

will only print 0-9.

Until next time.

Site Updated.

Moved to wordpress. Have been wanting to update @Joe Montana Jersey the site for @Joe Montana Authentic Jersey a @Joe Montana Womens Jersey while now.

October 26th, 2006

The Site is Alive!

Finally the site works again, and the symbolizer @Reuben Foster Womens Jersey is available again. All it took was a host change – who would of thunk it.

Baby steps.

Hopefully, I’m going to be bringing some @Reuben Foster Youth Jersey interesting things @Reuben Foster Kids Jersey back to the web again.

Take it easy everyone.

What I’ve been up too.

Hey guys,

Well, I’ve been busy. I’ve moved into my own place in Murfreesboro, TN. It’s pretty cool up here. I’ve got some great neighbors and I’m located within 5 feet of a pool. Overall, everything is going well.

As for working on my own stuff, I haven’t had much time. Actually, I’m still settling in to my new place, and driving back and forth to my old house every other weekend, so its taking some time to get used to stuff. I plan on working on some projects as soon as I feel comfortable.

At work I’ve been learning some pretty cool @Andrew Luck Jersey stuff. Recently, I’ve been working with VMWare which turns out to be pretty cool. You can run multiple OS’s on a single box, which I can see as being a major money-saver.

I’ve also been working with Oracle – Oracle is not fun. It is way @Andrew Luck Authentic Jersey too complicated for what I would consider an “enterprise level” database. My idea of “enterprise level” is easy to use, easy to maintain, and as flexible as possible. Two of those things are missing. Now, that’s my humble opinion, but if I was paying thousands of dollars, I would require those three things out of a database, especially since there are free databases out there that have 75% of the above three attributes.

I’ve seen those Oracle Guru’s out there with their huge ego’s learning complicated software for the sake of learning @Andrew Luck Womens Jersey it. Why make it any easier and put those $100,000 a year oracle admins out of work? I always see this elitism on the forums when I’m looking through old posts of people asking for help. I guess I’m not a member of the in-crowd quite yet, and I’m not entirely sure I want to be.

Well I’m getting of this machine for awhile,

Take it easy everyone,

RUBY - The True Language of Love

Hey guys,

Well I finally Graduated with Honors from the University of North Alabama. I?m glad to see it finally end, but also a little sad about saying good bye to some of the friends I made there this past year. I?ve suddenly been left with a lot of time on my hands, so I?ve been practicing RUBY.

RUBY is an awesome programming language that, in my opinion, is a real joy to use. I?ve been playing around with it for the past month or so. It took me all but a weekend to get the hang of the syntax, and now I?ve been learning to do more complex things with it. I like it better then even PYTHON, which was my previously held language champion. There is just something about @Jerry Rice Womens Jersey RUBY that makes it fun to use.

Now that I?ve said that I love it, let me bring it back down to earth a bit about somethings I don?t much care for. For one thing, it?s not widely supported (yet). Secondly, there are still some bugs on the Windows-side of things. Finally, this one is somewhat related to the first, it?s hard to get it working on an APACHE webserver.

Once all these things are figured out ? I think it will really take off. Obviously Windows is the most popular OS, so getting all @Jerry Rice Youth Jersey the developer bugs out of it is a must. Apache is the most popular webserver, so the same goes for it.

Sometimes, I wish that a language like RUBY could be the good old compiled kind. So I?d never have to use C++ again, but alas ? it is not. I?d also like to see a GUI toolkit that is simple to use or at least works just like the language that uses it. The closest thing I?ve seen is wxRUBY for RUBY, but I still don?t like somethings about it.

I?m quickly beginning to realize that it?s not the programming language that makes @Jerry Rice Kids Jersey the language fun, its more the tools you use to develop with, that make it fun.

For example, I hate hand typing every little tag in an HTML page, so I use dreamweaver to speed up my workflow ? sure you have to still know HTML to make corrections or minor modifications to generated code, but it still works really well.

The same hold true with Visual C++,C#,J#,BASIC, ETC. It just makes the language more useable instantly. Keeps me from having to type everything in.

So, now I await a Visual RUBY application. I might be smart enough to do it myself ? one day. You never know.

You guys take it easy,

Jim

Site Update Coming Soon

Hey guys,

Been a while, just want to let everyone know that I’ll be competely relaunching the site with a new design pretty soon. I’m going to try to use the same backend as I have been using-so as to avoid URL changes.

On another note, I’ve hit a little snag. My laptop, in which I do all of my work on, has broken. So, I’ll be completely without my machine for two weeks, which will definetly put a snag in my work. I’m @Joe Montana Youth Jersey hoping to raise enough money to get an Apple computer- cause I’m sick of the whole Wintel thing.

As for the future, I plan on writing some more flash extensions-during a slow build up to SYmBolizer 2.0. I’ve got some utilities that once written will help bring together several extensions into a workflow powerhouse. Unfortunately, I’ve been incredibaly busy these last few months- having to program/ design/ go to school /etc. So, the @Joe Montana Kids Jersey sooner I get to it the better.

Also check out mudbubble.com he’s got a new @Joe Montana Jersey layout, with a flash layout coming soon.
