Hi All,

“We’re sorry, but something went wrong.” is the message I got when I  
started up an RoR app in the environment:

Rails 2.3.5  
Ruby 1.8.6  
WinXP-Pro/SP3  
Firefox 3.6  
MySQL 5.0.37-community-nt  
Mongrel

The app under development was working fine until I (stupidly) thought  
I needed to upgrade MySQL to 5.1.44.

I took the precaution of MySQL-dumping  
the development db before upgrading. Then I ran into problems which  
led me to switch back to a clean install of 5.0.37 and reboot.

I used MySQL to reinstall the development db and tested it  
successfully under the MySQL client.

I started up Mongrel and ran my app using localhost:3000, getting the  
captioned message.

The development log is presented below. Suggestions are extremely  
welcome.

Thanks in Advance,  
Richard

I think you may have a similar issue. The post may not solve your issue,  
but it should get you going in the right direction.

Hi Aldric & Sandip,

Thanks for your ideas. It’s great to have friends around the world.

After I posted the message, I went on a bug hunt that, after two  
hours, revealed that the message should have been supplemented with:  
Database “RTS\_Development” does not exist". Then I would have known  
that my restoration of the development database was mis-named. The I  
would have exported the bad and renamed my import.

But alas, I had to find this out for myself. There was no way I  
could have posted all the details of my misadventure to y’all so that  
you’d have a chance at spotting my error.

So, again, thanks. I’m OK for now, but another problem will crop up  
soon, no doubt.

Best wishes,  
Richard

I’ve got the entire application back to where I was before I thought  
upgrading MySQL might be the solution to my problem.

The problem was that I added an expense item which included an amount,  
say 10.50. After saving the new item, the expense amount displayed  
as simply 10 – no .50 anywhere. I finally realized my problem was  
scale=0 for my amount column.

I generated/edited this migration to fix my problem. Do you think it  
will work if I use rake to apply it?

class ChangeExpenseTblAmountCol \< ActiveRecord::Migration  
def self.up  
class Expense  
change\_column :amount, decimal :precision=\>10, scale=\>2  
end  
end

def self.down  
end  
end

Or should I have simply changed the class name (which is simply the  
name I gave to the generator).  
I’m running Rails 2.3.5, Ruby 1.8.6 and MySQL 5.0.37-community-nt

Richard,

Straight to the point.

There are a few ways to get out of this problem, most of them driving  
you to a MySQL DLL downgrade.

IMHO, the fact is MySQL 5.1 doesn’t work properly with RoR, so, stick  
with 5.0, report the problem to MySQL staff and wait for: an official  
patch for 5.1, or for the 5.2 hoping it will solve the problem.

That is it.

Pleas check your routes.rb file and configure your map.root  
parameter. You can use the tutorial below or assistance.
