I have a Ruby on Rails site that uses thinking sphinx for searching a postgres database. One of the fields in a table I am searching on is a boolean. I'd like to be able to match on that boolean when a certain keyword is used in the search query. To fully explain with an example: My site is for people who develop their own black and wh...
I'm writing a simpler version of phpMyAdmin in Rails; this web app will run on a web server (where users will be able to indicate the database name, hostname, username, password, and port number of one of the database servers running on the same network). The user will then be connected to that machine and will be able to use the UI to a...

Hi, I have a relatively simple Rails app and I would like to store various configuration settings that administrator users can change whilst the application is running, for example, allowing comments on posts or changing the display format of the date.

In Ruby on Rails you can easily convert "any" text into a format which would work for subdomains/pathnames. 1) "I am nobody." -> "i-am-nobody" 2) "Grünkohl is a german word." -> "grunkohl-is-a-german-word" I'd like to do this on the client-side for high responsiveness (alternative would be via Ajax). The last example is called transl...

I am a newbie working in a simple Rails app that translates a document (long string) from a language to another. The dictionary is a table of terms (a string regexp to find and substitute, and a block that ouputs a substituting string). The table is 1 million records long.

I am working on developing a skeleton of what to eventually become an administration dashboard. One of the things the dashboard will eventually have to do is allow users to search for users of a game and view information about them. The information about them in question is in different table so naturally I have had to employ associati...

The performed? method returns true in a controller if the application has redirected or rendered. How can I determine whether the application rendered (rather than redirected)? Judging from the performed? docs, I can look at @performed_render, but this seems hacky. Edit: Why do I want to do this? I'm trying to cache the output of a c...
Hi! Normally rails loads data with a :select => "*" from the database. I know I could change this. But I'd like to go another way: always only select "id" and load the attributes automatically later on when they are needed. Example: accessing user.description should if it's been loaded yet. if not, trigger a "SELECT description FROM us...
On my rap lyrics explanation website, every user has an associated "favorites" page at http://rapgenius.com/USERNAME Because these favorites pages occupy the root namespace, I have to make sure that no one takes a username that I'm already using for something else. E.g.: /songs /lyrics /users /posts How can I look up all top-level p...
