Ruby and Rails http://ruby.zigzo.com Just another Zigzo.com weblog Sat, 03 Apr 2010 20:47:29 +0000 http://wordpress.org/?v=2.8.6 en hourly 1 Woes of The Jeweler Gem & .gitconfig http://ruby.zigzo.com/2010/04/03/woes-of-the-jeweler-gem-gitconfig/ http://ruby.zigzo.com/2010/04/03/woes-of-the-jeweler-gem-gitconfig/#comments Sat, 03 Apr 2010 20:38:37 +0000 admin http://ruby.zigzo.com/?p=56 I wanted to play around with creating my own gems so today I decided to try the jeweler gem.

Install went fine:

io@love:~$ sudo gem install jeweler
Successfully installed jeweler-1.4.0
1 gem installed
Installing ri documentation for jeweler-1.4.0...
Installing RDoc documentation for jeweler-1.4.0...

But when i attempted to create “the perfect gem” I ran into a bit of a problem:

io@love:~/ruby/gem_test$ jeweler the-perfect-gem
/usr/lib/ruby/gems/1.8/gems/git-1.2.5/lib/git/lib.rb:700:in `command': git config "--global" "--list"  2>&1:fatal: unable to read config file /home/io/.gitconfig: No such file or directory (Git::GitExecuteError)

	from /usr/bin/jeweler:19:in `load'
	from /usr/bin/jeweler:19

And after some research… looks like i had not done some mandatory git setup steps… as i SHOULD have.

The solution…

io@love:~/ruby/gem_test$ git config --global user.name "iouser"
io@love:~/ruby/gem_test$ git config --global user.email "iouser@gmail.com"
io@love:~/ruby/gem_test$ git config --global github.user iouser

And finally the glory:

io@love:~/ruby/gem_test$ jeweler the-perfect-gem
	create	.gitignore
	create	Rakefile
	create	LICENSE
	create	README.rdoc
	create	.document
	create	lib
	create	lib/the-perfect-gem.rb
	create	test
	create	test/helper.rb
	create	test/test_the-perfect-gem.rb
Jeweler has prepared your gem in the-perfect-gem

Note: If you see the this error

io@love:~/ruby/gem_test$ jeweler the-perfect-gem
No github.user found in ~/.gitconfig. Please tell git about your GitHub account (see http://github.com/blog/180-local-github-config for details). For example: git config --global github.user defunkt

it means you forgot to do this part:

In plain english, I needed a list of blogs ordered by most recently updated feed.

My models look like this:

blog.rb
has_many :feed_entries

feed_entry.rb
belongs_to :blog

The query that makes it possible:

Blog.find(:all, :include => :feed_entries, :order => 'feed_entries.published_at DESC')

:include makes this possible!

This one is pretty easy, but you should know that you HAVE to be using MySQL or PostgreSQL because google_maps uses the spatial adapter plugin which needs one of those 2.

First install the GeoRuby gem.  Careful this is case sensitive:
sudo gem install GeoRuby

Next, from within your Radiant project’s root folder, clone the extension from github:
git clone git://github.com/rurounijones/radiant-google-maps-extension.git vendor/extensions/google_maps

Time to run the Rake tasks:
rake radiant:extensions:google_maps:api
rake production radiant:extensions:google_maps:migrate
rake production radiant:extensions:google_maps:update

Edit config/gmaps_api_key.yml and add your own Google Maps API key.

Add this R tag inside your layout’s head tag:
<r:google_map:header />

Goto the Maps tab in the Radiant Admin and create a map

Create a new page and name it something.  In the body of that page add:
<r:google_map:generate div=”my_gmap_div_name” id=”1″ />
<div id=”my_gmap_div_name” style=”height: 600px; width: 868px;”></div>

That provides a div for the map to go in, and calls the google_map generate tag with Map id 1.  Look on the github page for more stuff.

First, make sure ray is installed… if it’s not, just run
./script/extension install ray

Second, install the extension!
rake ray:extension:install name=first-reorder

This reorder extension is pretty nice.  It provides an ajaxish layout for drag/drop reordering.

I am going to go through installing the News extension on Radiant 0.7.1.

Based on the install info for News it says you need to install calendar_date_select and points you at their page.  Their google code page says you can simply do:

sudo gem install calendar_date_select

Yeah, so,  for some reason that doesn’t work. Skip that step and do the rest, we will address it later.

1)  Clone from github!

git clone git://github.com/screenconcept/radiant-news-extension.git vendor/extensions/news

2) Run the Migration and Update tasks

rake production radiant:extensions:news:migrate
rake radiant:extensions:news:update

Know that you can swap out “production” or add in whatever environment you want.

3) Finally we install the calendar_date_select PLUGIN not the gem! I could not get this thing working with the gem.

git clone git://github.com/timcharper/calendar_date_select.git vendor/plugins/calendar_date_select && rm -rf vendor/plugins/calendar_date_select/.git

4) Weeeeee :)

I’m notating this because both the Radiant wiki and Mailer’s github page have instructions that confused the hell out of me so I’m consolidating it here after getting it working.

This tutorial assumes you have a freshly bootstrapped Radiant installation. Let’s Go!

1) I like the Ray extension for installing stuff so first we install Ray:

me@coffee-bean:~/railz/radiant$ ./script/extension install ray

2) After Ray installs, we can easily use it to install the Mailer extension:

rake ray:extension:install name=mailer

3) After the Mailer extension is installed, we have to modify ‘config/environment.rb’ so that it is no longer excluding the ActionMailer framework.  Find the line ‘config.frameworks -= [ :action_mailer ]‘ and change it to just ‘config.frameworks -= []‘.

While environment.rb is open, we need to make one additional change.  We need to add our SMTP settings.

Find the line ResponseCache.defaults[:logger] = ActionController::Base.logger.  If you have not modified enviornment.rb before this time, then it should be Line 84.  Below that line but before the next ‘end’ add the following:

ActionMailer::Base.smtp_settings = {
:address => "smtp.domain.com",
:domain => "domain.com",
:user_name => "user@domain.com",
:password => "password",
:authentication => :login
}

4) Create a child off of your Home Page in the Radiant Admin and called it “Contact Us”

5) Open the “Contact Us” page and create 2 parts.  Name the first part ‘mailer’.  Name the second part ‘email’.
The ‘mailer’ part holds our mail config stuff.
The ‘email’ part is the template for the email that is sent out.  This can be named ‘email_html’ if you feel like adding html to the body of your email.  ‘email_html’ also supports Textile and Markdown.
The ‘body’ part (body is there by default in any page) is where the actual mailer form will go.

6) Put this in the ‘email’ part:

Name From: <r:mailer:get name="name"/>
Email From: <r:mailer:get name="email"/>
Body Message:
<r:mailer:get name="message"/>

7) Put this in the ‘mailer’ part, but NOTE this is YAML so indentation matters (2 spaces):

subject: "Sent from your contact us form"
redirect_to: /contact/thanks-for-contacting-us
from_field: email
recipients:
  - you@example.com

Side note 2, the redirect_to is where the user is sent After submitting the form. Obviously, if you set this to some page, you will need to create that page.

8) Put this in the ‘body’ part (or whatever part you want the actual form to live in):

<r:mailer:form name="contact">
<fieldset>
<legend>Enter your contact information and message.</legend>
<r:text name="name"/> <label for="name">Name</label><br>
<r:text name="email"/> <label for="email">Email</label><br>
<label for="message">Message</label><br>
<r:textarea name="message"/><br>
<input type="submit" value="Send">
</fieldset>
</r:mailer:form>

9) Profit!  Try it out.

It just so happens that a gentleman named Benny Degezelle has created an extension for Radiant CMS.

At the time of this writing I’ve installed this bad boy on Radiant CMS 0.7.1.

FIRST

Assuming that you have an already bootstrapped (aka ‘rake production db:bootstrap’) installation of Radiant CMS you should first clone the extension from GitHub while in your application’s home directory:

me@world:/www/radiant.domain.net$ git clone git://github.com/jomz/radiant-wym-editor-filter-extension.git vendor/extensions/wym_editor_filter

The command above will clone it to /vendor/extensions/wym_editor_filter

SECOND

Run the Install rake task!

me@world:/www/radiant.domain.net$ rake radiant:extensions:wym_editor_filter:install

THIRD

Run the Update rake task just to be safe.  You can run this at a later point in time to update, obviously.

me@world-www:/www/radiant.domain.net$ rake radiant:extensions:wym_editor_filter:update

So, according to paul dix, to get this baby installed you need to run:

io@crazo:~$ sudo gem install pauldix-feedzirra

If that works, please carry on with life and have some funs with RSS. If you get the following error the fix MIGHT be as simple as installing libcurl3-dev:

io@crazo:~$ sudo gem install pauldix-feedzirra

After reading that butt load of output i noticed this line:

extconf.rb:9:   Can't find libcurl or curl/curl.h (RuntimeError)

Two flags here: 1. the bitching about curl makes me think i don’t have curl installed and 2. curl.h = header and normally the header stuff is in the dev package so I should try that out.

io@crazo:~$ sudo apt-get install libcurl3-dev

FYI, if you want to install gems from GitHub you need to add it as a source!

How? Easy!

sudo gem sources -a http://gems.github.com

Now you can install any gem hosted on GitHub with something like:

sudo gem install yo-mama

One other thing to note. Gem names when installing from GitHub are formatted as: username-projectname

So if you were looking @ user “billybob” and he forked a gem/project called “fishface”… the way you install would be:

sudo gem install billybob-fishface
