I have a has_many :through relationship associating players to teams THROUGH managements. I want to have a counter on the teams table (a bit like a counter cache) that tells me how many new associations there have been since the beginning of the week.

This is probably something very simple but I'm looking for the optimal way of retrieving all Products by Tag, so to speak. This is with Spree, so I should stick to the way they have modeled their data. It's actually Product and Taxon (like category, brand, etc.) So if Product has_and_belongs_to_many :taxons and Taxon has_and_belongs_t...

I hear claims that Ruby on Rails makes web applications ten times faster to write. Is this really true? Do they just make a bunch of tools to make the simple stuff fast and the hard stuff impossible (without serious refactoring)? Can it handle difficult web problems like an advanced searches and AJAX webgrids? Can't other languages j...
