Ruby on Rails: Replacing the “LIKE” part of the SQL query with Ruby code



Category : Databases

In my application I have a "LIKE" SQL query that is something like...


Item.where("name LIKE ?", "%"+params[:q]+"%").all

But I want to hit the db only 1x (at application start-up), since the number of Items is huge, and load this generic part...


Item.all

...into memory (a global variable), so I can later reuse its content throughout the app, in different cases, and refined with some case-specific Ruby code (see the "LIKE" part).


What's the speediest way to do such "filtering" with Ruby?

Does the hoster has to support “Ruby on Rails” or “just Ruby” to run Rails?
Category : Programming Languages

Does the hoster have to support "Ruby on Rails" or "just Ruby" to run Rails?


I know mainly PHP and ask myself if "Ruby on Rails" behaves to Ruby ... like "Zend Framework" to PHP: just a bunch of PHP files I can copy in my project folder and my hoster only needs to support PHP.

Can Ruby on Rails cache a Controller “as long as code is not changed”?
Category : Programming Languages

At work, we have a situation where when


script/server

is run, then all the controller code is cached. This is to speed up the
development server. But that will mean that whenever we change the
controller code, we need to restart the server.
