I’m trying to get my routes to work properly. Here’s how I’m defining  
one of my routes:

map.downloads ‘:category/downloads’, :controller =\> ‘downloads’, :action  
=\> ‘list\_downloads\_for\_category’, :requirements =\> {:category =\>  
DownloadableFileCategory.category\_regex}

And here’s the method definition for  
DownloadableFileCategory.category\_regex:

def self.category\_regex  
regex\_str = “”  
for category in DownloadableFileCategory.find(:all)  
regex\_str += category.category.downcase  
regex\_str += “|”  
end

```
Regexp.new(regex_str.chop, Regexp::IGNORECASE)

```

end

This creates a regex such as /admissions|jobs/i so that the url  
/admissions/downloads maps to the list\_downloads\_for\_category method  
with params[:category] = “admissions” and /jobs/downloads maps to the  
same method with params[:category] = “jobs”. That part works correctly.

The part that’s not working is the Regexp::IGNORECASE option. URLS such  
as “/Admissions/downloads”, “/ADMISSIONS/downloads” do not match this  
route even though I’ve set the regex to ignore case. I tried testing  
just the regex in script/console and it worked just fine. It just  
doesn’t work when trying to match the URL.

Why doesn’t this work?

Thanks,  
Myron

try

map.admissions ‘admissions/downloads’, controller =\> ‘admissions’

before you define the stuff you just defined.
