msvcrt-ruby18.dll Error on Windows.

When using ruby 1.9.2p136 (2010-12-25) [i386-mingw32], Rails 3.0.3, cucumber (0.10.0), cucumber-rails (0.3.2), and rspec (2.4.0) I was getting a windows error message saying that I don't have msvcrt-ruby18.dll and I need to fix it.

This is on a new ruby and rails set up. When I added my testing gems rspec and cucumber I started getting that error when I ran rake or started the webserver.

I commented out the testing gems and traced it to cucumber.

When looking at comment on Stack Overflow I noticed someone mentioned reinstalling json.

I looked to what version I had.

sqlite3-ruby 1.3.2 on Windows 'Error'

2010-12-14T11:00:00.000-08:00

When I created a new rails app ran bundle install I noticed a new version of sqlite3-ruby was installed.

...
Installing sqlite3-ruby (1.3.2)

When I tried to start the server I got this message.

I thought I'd reinstall it, since that's what one does on windows, and I got some more information.

C:\web\testapp>gem install sqlite3-ruby

=============================================================================

You've installed the binary version of sqlite3-ruby.
It was built using SQLite3 version 3.7.3.
It's recommended to use the exact same version to avoid potential issues.

At the time of building this gem, the necessary DLL files where available
in the following download:

http://www.sqlite.org/sqlitedll-3_7_3.zip

You can put the sqlite3.dll available in this package in your Ruby bin
directory, for example C:\Ruby\bin

Let's look at what was installed.

C:\web\testapp>gem list --local -d sql

*** LOCAL GEMS ***

sqlite3-ruby (1.3.2)
Platform: x86-mingw32
Authors: Jamis Buck, Luis Lavena, Aaron Patterson
Rubyforge: http://rubyforge.org/projects/sqlite3-ruby
Homepage: http://github.com/luislavena/sqlite3-ruby
Installed at: C:/Ruby192/lib/ruby/gems/1.9.1

This module allows Ruby programs to interface with the SQLite3
database engine (http://www.sqlite.org)

I downloaded the file at http://www.sqlite.org/sqlitedll-3_7_3.zip and copied the DLL into my C:\Ruby192\bin folder since that's where I have it installed.

Let's give it a try

C:\web\testapp>rails s

It works.

Make An HTML Version of the iPhone's Contact Screen.

2010-11-30T06:26:00.000-08:00

Make An HTML Version of the iPhone's Contact Screen.

We want this, but not so blurry.

I'm going to break it down with a heading, text and a list. I'll go with a definition list. We define the phone numbers, email and address.

Let's mark up the base.

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Person</title>

<style>
article, aside, details, figcaption, figure, footer, header,
hgroup, menu, nav, section { display: block; }
</style>
</head>
<body>
<h2>John Ivanoff</h2>
<p>Some Company</p>
<dl>
<dt>work</dt>
<dd>972-555-1212</dd>
<dt>home</dt>
<dd>972-555-1212</dd>
</dl>
<dl>
<dt>work</dt>
<dd><a href="mailto:unknown@unknown.org">unknown@unknown.org</a></dd>
</dl>
<dl>
<dt>work</dt>
<dd><a href="http://goo.gl/1nTU8">123 Chicago Ave<br/>Lebanon, KS 76051-7693 </a></dd>
</dl>
</body>
</html>

View it in a browser and we get.

We have the foudation. Now let's add some style.

We'll start with the background of the page.

body {
background-color: #ddd; /* Background color */
color: #222; /* Foreground color used for text */
font-family: Helvetica;
font-size: 14px;
margin: 0; /* Amount of negative space around the outside of the body */
padding: 0; /* Amount of negative space around the inside of the body */
}

View it in a browser and we get.

Let's get the lists styled.

We'll add the white background and border.

dl {
list-style: none;
padding: 0;
}
dt, dd {
background-color: #fff; /* Background color */
color: #222222; /* Foreground color used for text */
border: 1px solid #999;
font-weight: bold;
margin: 0;
padding: 12px 10px;
}
dt:first-child {
-webkit-border-top-left-radius: 8px;
}
dt:first-child + dd { /* This rounds the first definition item */
-webkit-border-top-left-radius: 8px;
-webkit-border-top-right-radius: 8px;
}
dd:last-child {
-webkit-border-bottom-right-radius: 8px;
-webkit-border-bottom-left-radius: 8px;
}

View it in a browser.

We'll style the 'terms.' We'll make them 60 pixels wide, have the text align to the right and make it a little lighter in color.

dt {
color: #516691;
text-align: right;
width: 60px;
}

View it in a browser.

Now we'll move up the 'definitions' so it looks like one line. We'll float the dt

dt {
float: left; /* this will 'bring up' the dd */
color: #516691;
text-align: right;
width: 60px;
}

View it in a browser.

That doesn't look good. We'll remove the border on the dt and I'm picky here but I want to move the dt a little bit.

dt {
float: left; /* this will 'bring up' the dd */
border: 0; /* remove border */
padding-top: 13px; /* alignment tweaking */
color: #516691;
text-align: right;
width: 60px;
}

View it in a browser.

That's a little better but the top left looks like crud. The remedy? Make the color of the dt transparent.

dt {
float: left; /* this will 'bring up' the dd */
border: 0; /* remove border */
padding-top: 13px; /* alignment tweaking */
color: #516691;
text-align: right;
width: 60px;
background-color: transparent; /* clears up the top left corner */
}

View it in a browser. Bam!

Looking good.

Let's work on the name and company. We'll wrap a div around the contact name and company

.......

<div id="namecompany">
<h2>John Ivanoff</h2>
<p>Some Company</p>
</div>

.....

We'll add this image like the on for a contact without a photo

div#namecompany{
padding-left: 90px; /* Makes room for the photo */
background: transparent url(../i/person-icon.png) 10px 0 no-repeat; /* This sets up the position of the image */
height: 70px; /* Set the hieght of the div */
}
div#namecompany h2, div#namecompany p {
margin: 0; /* Just smash it all together */
}

View it in a browser.

We're starting to cook with gas. A few minor areas to touch up. We need padding around the page.

We can hack it and add a margin to the entire page. The problem with that is when we add a header or footer that will ruin the look. The header or footer will not span the width of the screen.

What about wrapping everything in a div content? That add unnecessary HTML.

For this simple layout I'll add the padding to the namecompany div and the lists

div#namecompany, dl {
margin: 10px;
}

View it in a browser.

Smashing. Be'll make the phone numbers into links so we can call

...

...

View it in a browser.

Let's hide those ugly links.

a {
text-decoration: none;
color: #000;
}

View it in a browser.

With this current design if you have a really long email the email will wrap just like the address. In the contacts app on the iPhone long emails are truncated with a trailing ellipsis.

We'll add a home email and make it a really long email address and we'll add a class of email to the dd

...

<dl>
<dt>work</dt>
<dd class="email"><a href="mailto:unknown@unknown.org">unknown@unknown.org</a></dd>
<dt>home</dt>
<dd class="email"><a href="mailto:unknown.unknown@areallyreallyreallylongurl.org"> unknown.unknown@areallyreallyreallylongurl.org</a></dd> </dl>

...

View it in a browser.

That's not good.

Let's add an ellipsis to text that is too long for its container.

.email {
overflow: hidden;
white-space: nowrap;
text-overflow: ellipsis;
}

View it in a browser.

Still not good.

.email {
overflow: hidden;
white-space: nowrap;
text-overflow: ellipsis;
display: block;
width: inherit;
}

Update…

That code will render like the previous image.

Move the .email class into the a element. The a element should look like the following

a {
text-decoration: none;
color: #000;
overflow: hidden;
white-space: nowrap;
text-overflow: ellipsis;
display: block;
width: inherit;
}

Then remove the .email class from the <dd> for the emails,

Moving that code to the a element will also insure that any long text will be shortend to stay within the page.

View it in a browser.

Hurray!

Let's add some finishing touches.

A title bar and the pinstriped background. Add this to the html code.

...

...

Add to CSS code.

body {
background: #ddd url(../i/pinstripes.png) repeat scroll 0%;
color: #222; /* Foreground color used for text */
font-family: Helvetica;
font-size: 14px;
margin: 0; /* Amount of negative space around the outside of the body */
padding: 0; /* Amount of negative space around the inside of the body */
}

...

h1 {
color: #222;
font-size: 20px;
font-weight: bold;
margin: 0 auto;
padding: 10px 0;
text-align: center;
text-shadow: 0px 1px 0px #fff;
background-image: -webkit-gradient(linear, left top, left bottom,
from(#ccc), to(#999));
}

View it in a browser.

There we go, a web page that looks like a native iPhone app.

Notice bundler installed sqlite3-ruby(1.3.1).

Let's look at the gems again.

C:\testapp>gem list --local

*** LOCAL GEMS ***

let's start the server!

If you get and error message about the SQLIte3 gem, here's how I solved it.

C:\testapp>rails s

What are we running?

Have fun.

Next we'll get it to hook up to MySQL

Create A Rails 3 beta With Authlogic, Declarative Authorization a

2010-06-14T07:14:00.001-07:00

Create A Rails 3 beta With Authlogic, Declarative Authorization and Cucumber

I have updated my auth_with_roles app to use rails 3.0.7. You can find the code at https://github.com/johnivanoff/auth_with_roles/tree/rails_3_0_7

This was done on a windows wachine so forgive the C:\

And it's a crappy first draft.

My test aren't the best and need refactoring but this should get you started.

I plan to update this when rails 3 is released. I would also like to intergate Factory Girl.

This project uses:

Rails 3 beta 3, Git, authlogic, declarative_authorization, cucumber and rspec

Let's get going.

C:\web> rails auth_with_roles

C:\web> cd auth_with_roles

C:\web\auth_with_roles> git init

C:\web\auth_with_roles> git add .

C:\web\auth_with_roles> git commit -m "auth_with_roles Scaffold"

Let's add the gems for cucumber.

open /Gemfile add . . .

# Use Authlogic for security

gem "authlogic", :git => "git://github.com/odorcicd/authlogic.git", :branch => "rails3"

# using for role assignments

gem "declarative_authorization", :git => "git://github.com/stffn/declarative_authorization.git"

group :test do

gem 'capybara'

gem 'database_cleaner'

gem 'cucumber-rails'

gem 'cucumber', '0.7.2'

gem 'rspec-rails', '2.0.0.beta.8'

gem 'spork'

gem 'launchy' # So you can do Then show me the page

end

run

C:\web\auth_with_roles> bundle install

bootstrap your Rails app, for rspec:

C:\web\auth_with_roles> rails g rspec:install

Finally, bootstrap your Rails app, for cucumber:

C:\web\auth_with_roles> rails generate cucumber:skeleton --rspec --capybara

create the authlogic base.

C:\web\auth_with_roles> rails g cucumber:feature user username:string email:string password:string

C:\web\auth_with_roles> rails g scaffold user username:string email:string password:string

create_user migration

modify the user model /app/model/user.rb

end

we'll need to modify the cucumber test /features/manage_users.feature

Scenario: Register new user

Given the following roles:

|name|

|admin|

And I am on the new user page

When I fill in "Username" with "username 1"

And I fill in "Email" with "example@example.com"

And I fill in "Password" with "secret"

And I fill in "Password confirmation" with "secret"

And I check "admin"

And I press "Create"

Then I should see "username 1"

And I should see "example@example.com"

And I should see "admin"

Scenario: Delete user

Given the following users:

When I delete the 3rd user

Then I should see the following users:

|Username |Email|

|username 1|email1@example.com|

|username 2|email2@example.com|

Well we have some test to correct.

let modify the user session spec in /spec/controllers/user_sessions_controller_spec.rb

mock_usersession.should_receive(:destroy)

delete :destroy, :id => "37"

end

it "redirects to the login page" do

UserSession.stub(:find) { mock_usersession(:destroy => true) }

delete :destroy

response.should redirect_to(login_url)

end

Now modify the user's index spec /spec/views/users/index.html.erb_spec.rb

require 'spec_helper'

end

it "renders a list of users" do

render

response.should have_selector("tr>td", :content => "MyUsername".to_s, :count => 2)

Given /^I am logged in as "([^\"]*)" with password "([^\"]*)"$/ do |arg1, arg2|

pending # express the regexp above with the code you wish you had

end

in /featues/step_definitions/user_steps.rb add

Given /^I am logged in as "([^\"]*)" with password "([^\"]*)"$/ do |username, password|

unless username.blank?

visit login_url

fill_in "Username", :with => username

fill_in "Password", :with => password

click_button "Log in"

end

Let's update the users feature so we can select a role for a new users and admin can show edit or destroy. everyone can see a list of the users

In /features/manage_users.feature

Feature: Manage users

In order to manage Users

As an Admin

I want to manage users

@focus

Scenario: Register new user

Given the following roles:

|name|

|admin|

And I am on the new user page

When I fill in "Username" with "username 1"

And I fill in "Email" with "example@example.com"

And I fill in "Password" with "secret"

And I fill in "Password confirmation" with "secret"

And I check "admin"

And I press "Create"

Then I should see "username 1"

And I should see "example@example.com"

And I should see "admin"

Scenario: Delete user

Given the following users:

When I delete the 3rd user

Then I should see the following users:

|Username |Email|

|username 1|email1@example.com|

|username 2|email2@example.com|

|username 4|email4@example.com|

Scenario: Admin sees all user's edit links

Given the following roles:

|name|

|admin|

|guest|

And the following users:

And I am logged in as "don" with password "secret"

Then I should see the following users:

you might have noticed I added an @focus tag. We'll be running one scenario at a time now. we'll be able to focus on it.

Sam's Club MS 150 Frisco to Fort Wort...

2010-05-11T14:26:00.001-07:00

Sam's Club MS 150 Frisco to Fort Worth 2010

day 1

It's been over a week since we crossed the finish line. I think I have recovered. Back on that Saturday when I loaded my bike into the car, as I shut the trunk I thought "Did I just hear thunder?" Shortly after that it stared to rain. At the house it was pouring. I thought, "Not again." As I drove up to the start in Frisco the rain let up, thanks Connie. The parking lot was dry at the start. Finished getting dressed and took my bags over to the truck to be hauled to TMS. I decided to keep my rain jacket In hind sight I could have left it at home, who knew? Around 7:20 am the team I was riding with "Team Bike Mart" rolled out and started our journey. It's tough not to get caught up in the adrenaline and start ridding with the big boys and girls. At the third rest stop I overheard some people talking about keeping the pace around 17 mph. I asked if I could ride with them. We clipped along at a good pace. We had a good lunch. It's hard not to over eat.

Why there are those wicked little hills after lunch? that's just cruel. we rode along and stopped at a few stops but not all of them. I didn't get my yearly picture of me and Chester the Cheetah. As we were on the last leg of day one my legs reminded me that I had not been drinking enough. I was able to fight off the cramps. I drank heavily after the ride. I drank water not beer. we finished around 2 pm. here's the data from my ride.

Day 2

It was a little chilly in the morning. I decided not to wear a jacket hoping that it would get warm soon. as I was ridding out after stuffing myself full of pancakes and bacon, I noticed a group of riders from vipmotorcars.net and they looked like they would ride my pace. They started to do a rolling paceline and I was able to get in. We kept that going until the first rest stop. I the rest stop we introduced ourselves and I asked if I could tag along. "Sure" was what I heard. after that we picked up the pace a little and kepth the paceline rolling. We would pick up a few people here and there. We hit ever other rest stop. At one point we had a double paceline going since there were six of us. We made it through the hills and everything else. They were great to ride with. we crossed the finish line around 1 pm.

data from day 2*

*my "computer" didn't pick up my heart rate after lunch, but I finally got it back.

I'm ready to do it again.

install gem activerecord sqlserver adapter (http://github.com/rails-sqlserver/2000-2005-adapter)

C:\> gem install activerecord-sqlserver-adapter

I ran into a problem that it could install the gem so I have to dowdload devkit so it would "make" it has instruction on how to install.

installed devkit: unzipped rubyforge.org/frs/download.php/66888/devkit-3.4.5r3-20091110.7z

create a database on your SQL Server

Open your SQL Server client tool and create a database called sqlserverapp

Add a user with SQL Server authentication called user with secret as password to the database you just created.

Create an ODBC link name sqlserverapp to connect to this database.

Then you have to edit your database configuration file to tell rails to use SQL Server and your new database.

Create an ODBC link name sqlserverapp to connect to this database.

Edit the database.yml file.

Change the section under development with the following :

   development:
   adapter: sqlserver
   mode: odbc
   dsn: sqlserverapp
   username: user
   password: secret
   host: mycomputer

Note : replace mycomputer with the name of your instance of SQL Server (in most cases, locahost should do the job).

You should be god to go.

Please see Rails 2 and SQL Server 2008 on Windows made simple for more information on connecting to the MS Sequel Server.
