Great .gitignore file(s) for your next Rails project

Here's great rails template snippet to set up .gitignore files throughout your whole Rails project.

It ignores unnecessary files in the root .gitignore, plus it ensures no vendor/ directories are checked into git.

 
run "touch tmp/.gitignore log/.gitignore vendor/.gitignore" 
 
run %{find . -type d -empty | grep -v "vendor" | grep -v ".git" | grep -v "tmp" | xargs -I xxx touch xxx/.gitignore} 
 
file '.gitignore', <<-EOS.gsub(/^ /, '') 
.DS_Store 
log/*.log 
tmp/**/* 
config/database.yml 
config/initializers/site_keys.rb 
db/*.sqlite3 
EOS

active merchant's Authorize.net CIM gateway - support for prior auth capture

As the gem currently stands, Active Merchant's Authorize.net CIM gateway supports 3 transaction types:

      CIM_TRANSACTION_TYPES = {
        :auth_capture => 'profileTransAuthCapture',
        :auth_only => 'profileTransAuthOnly',
        :capture_only => 'profileTransCaptureOnly'
      }

If you make an auth_only call and later make a capture_only call with the same approval code, the second capture_only call will capture unassociated with the initial auth_only. What you want is a prior_auth_capture against the transaction ID from the initial auth_only.

You need this patch from Ben Wiseley:
http://github.com/wiseleyb/active_merchant/commit/608a17bfb4f4f1abc0da8a153f2842e26240d1cc

It adds these new transaction types:        

        :prior_auth_capture => 'profileTransPriorAuthCapture',
        :refund => 'profileTransRefund',
        :void => 'profileTransVoid'

The test code there is excellent. See test_should_create_customer_profile_transaction_auth_only_and_then_prior_auth_capture_request for a simple example of an auth_only followed by a prior_auth_capture.

Note that the fix includes a fix to the parse_direct_response method that is in Shopfiy's head, but not in the gem yet:
http://github.com/Shopify/active_merchant/commit/d05c089cdb383e5dc899da90af79afec5994f89d

I monkey-patched these changes manually by putting the overridden methods in a separate file in my lib directory and requiring that file in my app. There may be a better way but that worked for now.

I'm not sure why this patch has not been merged into the base yet. Here's the ticket:
https://jadedpixel.lighthouseapp.com/projects/11599/tickets/111-void-refund-and-auth_capture-for-authorizenets-cim-gateway

Heroku - the fastest way to getting a Rails app into Production

Ok, unless you already have a nice Capistrano deploy script lying around and a tasty Linode/Slicehost VPS, then Heroku http://heroku.com/ may just be the fastest way to get a Rails app deployed on a production system.

Its as easy as;

 
 sudo gem install heroku 
 heroku create 
 git push heroku master 
 heroku rake db:migrate 
 heroku open 

Sit back and watch your app open automagically in your browser.

Also note, Siyelo Fuselage http://github.com/siyelo/fuselage has been updated to be compatible with a Heroku deployment.

Converting Relative URL's to Absolute in Rails

So today's chores had me encounter outputting content from our CMS (String) to pdf using PrinceXML.  We are using the fantastic princely plugin to make this task dead simple, but upon initial testing I noticed a tragic absence of images and clickable hyperlinks.  OH NOES!  I whipped up a quick extension to String to take care of the issue:

Once dropped into your lib file of choice, your strings will be equipped to convert relative url's in image source and href tags with ease.

Nothing ground breaking here, just thought someone else might find it useful someday.

Announcing Fuselage - Get your Rails project off to a flying start!

Fuselage takes all the hassle out of installing several popular gems/plugins manually, as well as tidying up the default setup that the "rails" command gives you.

What's different about Fuselage? A lot of the Rails templates out there at the moment are quite primitive - a bunch of commands & files shoved in to a single file. Fuselage has a separate template for each gem/plugin, allowing you to specify all the relevant installs/commands/files/etc in one place. The goal here is to capture a lot of the setup logic that most Rails gems have in a single, reusable template.

Fuselage avoids asking a lot of questions, so if you want to customize your install, edit "template.rb" manually.

Usage is very simple. You can invoke it directly from your "rails -m" command with;

rails app_name -m http://github.com/siyelo/fuselage/raw/master/template.rb

(note this does a git clone of Fuselage for you automatically)

Or if you prefer, grab your own clone from http://github.com/siyelo/fuselage and set the FUSELAGE_DIR environment variable.

Full feature list

Currently Fuselage includes the following;

Rails
basic template for a clean a rails install
SCS
git
DB + Models
MySQL
authlogic
recaptcha
paperclip
Design/Layout
jQuery
haml
sass
compass + blueprint
formtastic
cufon
friendly_id
Controllers
make_resourceful
will_paginate
Testing
machinist
faker
cucumber
rspec
webrat
watchr - alternative to autotest
Search
thinking-sphinx
Security
tarantula
Metrics
metric_Fu
Production
passenger
capistrano
exception_notification

Extra templates included

These templates are included, but not installed by default. Manually edit template.rb to include them.

compass with 960 grid system
restful_authentication
forgery
asset_packager
whenever

Performing ActionMailer deliver_* methods for a new Model?

I'm thinking of implementing something like how ActionMailer does their dynamic deliver_* methods for this opensource rails messaging plugin I'm currently working on, but I'm not sure how should I go around working it.

I'm thinking of doing an easy-to-configure HTML templating system that would allow users to customize the output of commonly sent out messages.

But what do you think? Is it even necessary? Or am I adding code bloat.
