TextMate footnote plugin
Posted by jpb Tue, 11 Jul 2006 13:01:05 GMT
This plugin adds clickable links to the Rails backtrace when an error occurs, and clickable “footnotes” to the bottom of each page (in development mode only) that open the view or controller for the current page in Textmate.
In your plugins directory, install with:
svn export svn://syncid.textdriven.com/svn/opensource/textmate_footnotes/trunk textmate_footnotes

The Web is a pipe
Posted by jpb Fri, 30 Jun 2006 00:33:10 GMT
James Duncan Davidson has an interesting essay on The Web is a Pipe at his blog.
He brings up a lot of good points, especially about long-term support of your web application, that are applicable to things other than just Rails.
Paypal and Rails
Posted by jpb Sun, 25 Jun 2006 21:56:41 GMT
I was putting Paypal functionality into a Rails site I’m working on, using the paypal gem (which works great, btw), and ran into an annoying feature of the Paypal sandbox. I was looking at my sandbox Paypal transactions and they were all coming back “Pending” rather than “Completed”
It turns out that when you create a user in the Paypal sandbox for testing, if you only create a dummy bank account for it, any transactions you try to do with it will come back via IPN as pending, rather than completed. If you want your test transactions to come back with a “Completed” status, you have to add a fake credit card account to the sandbox user. I guess the fake banks don’t clear the echecks ;-).
Ruby on Rails meets DB2

IBM has an article on developing DB2 applications with Ruby on Rails here.
It includes a link to their DB2 adapter for Ruby.
TextMate backtrace plugin
Posted by jpb Wed, 21 Jun 2006 13:03:00 GMT
This makes the backtraces in error pages into clickable links that jump you directly to the line of the relevant source file. Too useful for words. In your vendor/plugins directory, install with:
svn export svn://syncid.textdriven.com/svn/opensource/textmate_footnotes/trunk textmate_footnotes
Got tired of having to manually drop tables when working on migrations
Posted by jpb Thu, 15 Jun 2006 06:16:00 GMT
I kept having typos in my migrations, and it turned out to be easier to just zap all the tables and re-run rake migrate than to undo just enough of the migration to get the db back to the way the migration was expecting.
Anyway, so I wrote this wipedb script that reads database.yml so you don’t need to maintain the database user & password in multiple places.
