I'm new to Rails, so forgive my ignorance of ActiveRecord. One of my models is named "campus". I ran the migration and it pluralized everything except "campus". I thought that was lame so I added the code to the environment config to leave everything singular. I deleted the tables, manually edited the migration files to use singu...
I'm looking to check if a string is all capitals in Rails. How would I go about doing that?

I'm not sure if this is feasible or even preferable But I'd like to build a has_many relationship or a conditional named_scope type relationship to ease my pain into one simple relationship instead of two. Currently I have two models which basically contain the same information and belong to the same Model rooms thru the same key room_...

Are there any gems that would help me make a search box like the one for tags on stackoverflow? (Rails 2.3.5, required IE7 support and graceful no-script fall-back) P.S.: Do these boxes annoy you or do you think it's a good thing to have one? ...
I'm trying to use the Attachment_Fu plugin in a Rails project, and want to customize the paths where uploaded files are saved. The documentation shows this option: :partition # Whether to partiton files in directories like /0000/0001/image.jpg. Default is true. (The 0001 part is an ID from a table.) I don't want that, s...

In my code I write them as follows: <img src="foo.png" /> <img src="foo.png" /> <img src="foo.png" /> <img src="foo.png" /> <img src="foo.png" /> <img src="foo.png" /> Note the line breaks in between the image tags. I write them that way for clarity. T...
Is is possible to create a recursive route in Rails? I have an application, which allows a admin to create pages. The page model is a nested set and so each page has a parent_id hence the pages are structured in trees. The page model also uses the Friendly ID plugin to provide slugs for each page. When a user browses the site I would l...
Let's say I have some models: User, Post, and Vote. A user has many posts and a post has many votes. Votes can be either an up vote or a down vote (stored as a boolean). What I am considering is the best way to do queries like these: All users, and the total number of up votes they've received. All users, and the post that has received...
