problems with rails scaffolding and installing mongrel

I'm not sure if this is necessarily the right forum for this.

When I build a new rails app (entitled 'tests') using scaffolding, the index page looks fine but when I click on 'new test' I get this:

NoMethodError in Tests#new

Showing app/views/tests/new.html.erb where line #3 raised:

undefined method `^' for "8":String

Extracted source (around line #3):

1: <h1>New test</h1>
2:
3: <% form_for(@test) do |f| %>
4:   <%= f.error_messages %>
5:
6:   <p>

And when I try to install mongrel as root or regular user, I get this:

Re: problems with rails scaffolding and installing mongrel

Hi!

I don't know if you've yet found a solution to it, but afaik this problem is caused by the ruby 1.9 version, because they don't use certain arrays anymore to compile.

You gotta wait for mongrel 1.1.6 or use webrick... oooooooor get ruby 1.8. That might solve the problem, but I haven't tried that yet.

If on the other hand it is related to gcc and make, then you're doomed and most definitely have to wait for a newer gem version. Uh yay... I've had this fun with the mysql gem last weekend... :>

Anyways, would be cool to hear, what you have found out...

Re: problems with rails scaffolding and installing mongrel

Just use thin for development, it's newer and better than mongrel.

Run your server with

script/server thin

or

thin start

in your Rails root.
