How do I handle uppercase and lowercase characters in a custom url?

I want to let users have links to their profiles using their registered usernames.

I store their username exactly how they give it.

I set up my routes to match /:name and then used find_by_name to get it. The problem I have is when you type in example.com/username it doesn't work the name: Username. (Note the uppercase/lowercase difference)

So my question is how can I ignore case in urls?

Easiest way is to convert the username in the database and in rails to lower (or upper) case when you are doing the comparison.

User.where('lower(username) = ?', params[:name].downcase).first

Or if you are still using rails 2:

User.find(:first, :conditions => ['lower(username) = ?', params[:name].downcase])

You can store the username downcased along with a display_name which is in the format they gave it to you. Then, downcase any input and match it with username and only use display_name for, well, display :)

If you wanted, you could even redirect to /DisPlAyName from /username after you look up the record.

One way to do this is to store a lowercase version of their username. When they type in

example.com/UsErNaMe or example.com/Username

downcase it and match it to the lowercase version in the database.

---OR---

Just make the user have a lowercase username everywhere. (Downcase it when its made)

---OR---

Have a constant type of username. So always have the first letter capitalized or something. Store it as lower case and upcase the first letter everytime you show it.
