Last months meetup was a blast! Who knew Rails generators could do some much and in so many languages? For the October meetup, Ruitao has promised an overview of his highly popular 'price aggregation' that scrapes the [probably shouldn't mention retailer] site.
But wait there's more ... I've also lined up a solid presentation from Omar Garcia a well respected computer scientist who's almost got a PHD! He's going to do a talk on AR's named scopes, a crucial feature for optimising or genericifying (that's a word right?) your AR based Rails app:
Here's Omar's run down:
Active Record Named Scopes
- Active Record goals
- What are Named scopes (new in rails 2.1)
- Simple Named Scopes
- What happens under the hood
new methods, Generated SQL
- Flexible named scopes
Using parameter
Using optional parameters
- Do's and Don'ts (optional I have some raw ideas on this topic)
- Related topics
Default scope (new in rails 2.3)
!-----xxXX Lots of sample code XXxx----!
Omar's such a legend I'm thinking we might not need the Circus Performers ... but Beer and Pizza come standard.
