Forum: Ruby on Rails ERROR NoMethodError: private method `gsub!' called

I have just upgraded to Ruby 1.8.7 and Rails 2.2.2.  My previous project
was at Ruby 1.8.6 and Rails 2.0.2.  My platform is Windows and Webrick
for development.

When I run Webrick, the server starts without error, the application
runs, database connections work and I can click through the pages and
display data.  But it does not serve any stylesheets or javascript
files.  What's interesting is that images are displayed.  In the log
file, I get a 500 error after it attempts to retrieve a stylesheet or
javascript.  This occurs everytime.

Example of attempt to retrieve prototype.js (a 500 error):
-------------
127.0.0.1 - - [17/Mar/2010:23:52:52 Eastern Daylight Time] "GET
/javascripts/pro
totype.js?1268882775 HTTP/1.1" 500 338
Referer -> /javascripts/prototype.js?1268882775
[2010-03-17 23:52:52] ERROR NoMethodError: private method `gsub!' called
for #<Class:0x44ee480>
-------------

If I type directly into my browser's address bar,
"http://localhost:3001/javascripts/prototype.js?126..., I get the
500 error message as above.  If I leave off "?1268882775", the browser
asks me to download the JS file.

I created a new rails app, started the webrick server, and it also
fails to run.

Any ideas what could be wrong?  I'm stumped.

Thanks,

Chris

Chris, when you switched your app from 2.0.2 to 2.3.5, did you run
'rake rails:update' in the root of your project?

It was to 2.2.2 and, yes, I did run 'rake rails:update'.  Not sure if it 
did anything.  It didn't give any output and returned to the command 
prompt.

Since I was at an old rails version I tried to just upgrade to 2.1 with 
not luck and then upgraded to 2.2.2 to see if that would help.  Same 
issue.

Thanks for the help.

Can you show us the rest of the error trace.

You can tell whether it changed anything by checking your current
version against the version in your version control repository.  If
you are not using one (git for example) start by setting one up.  When
messing about upgrading rails and so on you need to be able to track
what you have done, revert experimental changes, and so on.  A day or
two spent learning git will be recovered very quickly.

As much of the trace as I can get from my Windows command prompt.  It 
doesn't log this to log/development.log.  You'll see GET calls and then 
the 500 error followed by the "private method `gsub!'" error message 
repeatedly.  Seems to affect all of the static files---stylesheets, 
javascripts, images.  Sometimes it pulls images from my cache and if I 
refresh the page the image is missing again...

I use subversion.  Not much changed after executing "rake rails:update" 
on my current project. I think it mainly changed the boot.rb file.

What is odd is that I even created a new rails app from scratch and it 
is also having the same problem serving up anything from the public 
folder---stylesheets, javascripts, images, etc...  If I start webrick on 
this new app, it appears that the "new rails app" page loads with the 
images, but if I refresh, it immediately gives me the 500 errors on the 
static content.

I think I've worked through most of the other problems related to all 
the various plugins I'm using, but this issue still is puzzling why even 
a new rails app has the same problem.

Out of interest have you tried mongrel?
script/server mongrel

Otherwise I am out of my depth I am afraid.

Well, I executed "gem install mongrel", then "ruby script/server 
webrick" and everything is loading!!  What a bad problem with webrick. 
My staging server is mongrel, but my production is phusion passenger 
(which is a breeze to setup).  I hope Passenger will be kind when I make 
the next release to production!

I think it even cleared up an annoying "stack level too deep" error I 
was getting with webrick and not caching classes in development. 
Mongrel isn't complaining.

Thanks for your help!

I presume you mean "ruby script/server mongrel"

Yes... Sorry. Webrick still on the mind.

ruby script/server mongrel

Works!

To continue using Webrick, instead of switching to Mongrel, you can also 
just edit line 15 of lib/ruby/1.8/webrick/htmlutils.rb to read

      str = string ? string.to_s.dup : ""

The problem is that NotModified exception is getting passed to 
HTMLUtils::escape as a class, rather than a string (originally raised in 
HTTPServlet::DefaultFileHandler). Since the only things that can really 
be HTML escaped are strings, it should be safe to always convert the 
input to string.

I suspect that the potential performance penalty may prevent a solution 
like that from making it to the standard ruby library, but it's a simple 
workaround.

Alternatively, in the handle_file method of webrick's DispatchServlet 
(lib/webrick_server.rb in the rails gem), before it calls res.set_error 
with the exception, you could force the err.message to be a string, or 
even clear the message, since I think it's discarded anyway for 
NotModified.

Thank you very much! How very obvious to change that line. A pitty I
haven't tried to change it that way.

But now everything works just fine. I had the nearly same problem with
the same versions of Ruby and Rails but on Ubuntu. In my case
stylesheets etc. were loaded after some reloading of the page.

Thank you again!

thx it works for me :)
