Rails problem creating a new scaffold with mysql

Question

Im trying to set up a new scaffold with rails3, and mysql5.5. I got an error about couldn't parse YAML or something so I followed guidance on this question but now I get this error and I have no idea why.

C:\projectname>rails generate scaffold Website name:string

Any help solving this would be appreciated.

Sorry I was an idiot. I was just missing a space and got so annoyed that I must have overlooked something so simple. — Benjamin, Aug 09 '11 at 13:07

have you read the error message? it looks like you are missing colon, coma or something like this in your database configuration file. it is near the line with "host: localhost"
