Best way to get all my users onto the same domain?
I have about 10 domains pointing to my Heroku app (it took forever to settle on a name for the site -- don't ask), all of which I've given to various people at various times. Now that I've decided on a domain name (call it "example.com"), I want the existing domains to all work, but to redirect to example.com. What's the best way to do ...

Where to patch Rails ActiveRecord::find() to first check collections in memory?
For somewhat complicated reasons, I would like to create something that works like this: # Controller: @comments = @page.comments # comments are threaded # child comments still belong to @page ... # View: @comments.each_root { display @comment { indent & recurse on @comment.children } } # alternatives for how recursion call m...
OnChange problem with select_tag with '/' and '.' characters in Rails
I have an select_tag (rails) that loaded a select value with '/' and '.' character in it. The select tag's onchange redirects the page (using window.location) using concatenated url with the value of the select tag. These are the things I tried to isolate the problem.

How can I access an Interbase (.IB) database using RubyOnRails?

ORM that accepts SQL and simply maps the objects and relations?
I find that the use of ActiveRecord affects the way I design the database schema (though I wish it wouldn't). I'm thinking about the inefficiency of fetching data and how to reduce the overall number of queries. The find :include option can only get you so far. I come from writing stored procs that grab everything you need (for a part...
Redirect on record not found?
On the book Agile Web development with Rails, it is proposed that when someone tries to access some data in your web site and the record doesn't exist anymore, that the user should be redirected to a working page and display a message. A user would go to /book/1, but a book with id 1 doesn't exist anymore, so it is redirected to /books...
Views with Multiple Admin-ish Roles
I have an app where there are multiple "Admin-ish" roles. Imagine you have a super-admin that can edit anything, and also a site-admin that can edit any information about his site.

Implementing page controller all over rails
Hi All. I seem to have got a little a head of myself. I have created a Page Model and Pages controller. The whole idea was to be able to call something like 'print :controller=>'Pages', :action=>'view', :id=>'6', :layout=>'none'' And in my application.html.erb I have a div with yield, and in the next div I would like to have the above...
Guideline for code examples in job applications
Very often in job offers one is asked to provide some 'example code' together with the CV. I found it kind of difficult do decide which code is a good choice. Of cause it has to be meaningful code but on the other hand short enough to get a quick overview. It has to be well-documentated but not filled up with messy comments. Okay, sure...

[Rails] Routing: resource_path or resource_url?
When you do map.resources on a model, it generates a bunch of routing helpers: resource_path(@resource) resource_url(@resource) new_resource_url etc. What's the difference between using _path and _url? From what I've tried it doesn't seem to make any difference. ...
