How does one create a Rails migration properly so that a table gets changed to MyISAM in MySQL? It is currently InnoDB. Running a raw execute statement will change the table, but it won't update db/schema.rb, so when the table is recreated in a testing environment, it goes back to InnoDB and my fulltext searches fail. How do I go about ...

I'm trying to parse a URI with Ruby's URI library. This URI contains a #. For example, I have the URI: http://twitter.com/#!/dhh/status/26464821879 When I call URI.parse("http://twitter.com/#!/dhh/status/26464821879").path "/" is returned, when I would expect to see "/#!/dhh/status/26464821879" returned. How can I get URI.parse to pro...
Hello Everybody, This question is going to be very general because I do not know where to start. I want users of my service to be able to add their own custom url's.

I have an application that interacts with ActiveResource from a system I have no control of. It happens that the system sends me a JSON feed and one of the fields is called "type" and, everytime this model is serialized, I get this nasty exception. Since this is a CLI application, it's very annoying. Is there a way to silence this war...

Maybe I have misunderstood the whole concept of Arel, and I would be grateful if anybody could have a look at it. The expected result of th...
