There’s no way to design without color – even a strictly black-and-white site has multiple options for hue, contrast, and balance. With the lingering presence of flat design (now flat 2.0), color holds even more prominence in web design today….

I was getting this error with Rails 2.2 when using ActionMailer.

NoMethodError (undefined method `finder’ for #ActionView::Base:0x34146fc)

It stems from a line in engines/lib/engines/rails_extensions/action_mailer.rb

This is some problem between Rails 2.2 and Engines. Reinstalling engines didn’t seem to help.

Simply put, you need to go here and apply this patch:

This took me hours to figure out. I don’t know why there isn’t any more help on this problem.

After slogging through connecting Rails and Sugar via SOAP, I was tired and frustrated. The API is slow, and doing anything meaningful took a long time (ok, it took 30 seconds, but that seems slow to me; aren’t computers supposed to be fast?!). So, I came up with an alternative approach.

I know that Active Record (or whatever it’s called) in Rails is really just a fancy wrapper for the database. So, I created a second database connection, directly to the Sugar database!

I have long wanted to make sure my CRM system (SugarCRM) and my project management system synchonized certain data, mainly company names. I hate having to sync stuff like that manually. So, I’ve been working on integrating the data using a SOAP client on the Rails side. It took all day to get this working. I don’t know why this took forever to find out, or why there aren’t many good references on the Web. (Maybe I’m just dense!) read more >

This is another one that should have been obvious. But, I was getting it wrong. Maybe it had something to do with upgrading to Rails 1.2.6.

Anyway, I was getting an error with a custom action. I was sending a form to “projects/do_something”. But, I kept getting the error of “Can’t find project with ID=do_something”.

This was happening because Rails thought it was supposed to be looking in the route for the show action. But, checking the routes file, I could see that I had defined my custom route. What, what was up?
