Nov 22 2009 It's crazy how little documentation there is on using selects (drop down lists) inside form-helpers in Rails. So, it can get quite confusing when it comes to using the different select helpers; select, select_tag and collection_select. cialis 20mg price In order to address this inadequate documentation and examples, I thought I would post here, some of the differnces between them with some examples so you can choose for yourself, the best one to use.

The Bastards Book of Ruby The Bastards Book of Ruby Even though The Bastards Book of Ruby was going to just be a list of programming projects and snippets, this section is the least complete and consistent. Some portions have been written before I had decided to write all the other sections, so they contain thorough step-by-step instructions. Other portions – because I assume you've gone through the previous sections, or just out of laziness – do little more than describe the point of the code. Though many of the Fundamental and Supplementary chapters contain useful code examples, the Projects section attempts to walk through not just the code for specific situations, but the reasons behind exploring a dataset and the possible avenues of analyses and investigation. The code is a little more complex – and, at times, obtuse – but is meant to be readable by not-yet accomplished programmers.
