MetaWhere 0.5.2 – Debug your SQL

0 Comments

I just pushed version 0.5.2 of MetaWhere after some discussion on the Rails core mailing list, adding the debug_sql method. What’s the difference between debug_sql and to_sql, you ask?

MetaSearch and MetaWhere 0.5.0 released!

1 Comment

With the release of Rails 3.0.0.beta4 and Arel 0.4.0, all of the pieces have come together in gem form to allow a new gem release of both MetaSearch and MetaWhere.

I’m really excited about these releases, as they’ve been a long time coming. The last MetaSearch gem release was way back in March, while the last MetaWhere gem was released in April — this felt like an eternity in the fast-moving edge Rails world. :) I hope you enjoy the new release, and thanks in advance for submitting any bugs you find!

Now, on to what’s new since the last gem releases…

Arel merge!

0 Comments

Using MetaSearch and MetaWhere is about to become simpler, now that most of my Arel changes have been merged into rails/arel. Once a new Arel gem is released, I’ll make a new gem release of both of my libraries, as well. Thanks to Emilio Tagua (miloops) and Bryan Helmkamp (brynary) for the feedback and eventual merge!

Introducing MetaWhere

8 Comments

Recently, I spent some time working on a patch to Rails core to allow ActiveRecord::PredicateBuilder to allow more powerful queries — that is, support for additional Arel predicates beyond Equality and In. If you’re not familiar with PredicateBuilder, that’s where the magic happens when converting the arguments you supply to ActiveRecord::Relation#where or ActiveRecord::Base#find‘s :conditions hash into Arel predicates for a query. Anyway, after a brief discussion with Pratik on #rails-contrib, where he shared a bit of insight into his thoughts on tackling the same problem and encouraged me to create a plugin, I came up with a bit of a hybrid — something that I think scratches this particular itch pretty well for me: MetaWhere. Read on for how it works. [Update: If you're arriving via Ruby5 or the Rails weblog, you might also be interested in the latest MetaWhere updates, why I forked Arel, or the main MetaWhere page. Thanks for visiting!]

About

I'm Ernie Miller. But then, you probably knew that by looking at the page title, or the URL. I'm a Ruby programmer in Louisville, Kentucky. This blog used to be called "metautonomo.us", which I thought was kind of clever, but nobody, including me, could type it. Lesson learned.
