I have a migration in Rails that inserts a record into the database. The Category model depends on this record. Since RSpec clears the database before each example, this record is lost and furthermore never seems to be created since RSpec does not seem to generate the database from migrations.

Hi, I asked a question earlier about which language to use for an AI prototype. The consensus seemed to be that if I want it to be fast, I need to use a language like Java or C++, but that Python / Perl / Ruby would be good for the interface bits. So, this leads me on to another question. How easy is it to link these languages togethe...
I have a rails template (.rhtml file) generating a Javascript object. It looks something like the following: var volumes = { <% for volume in @volumes %> <%= volume.id %> : <%= volume.data %> <%= ',' unless volume === @volumes.last %> <% end %> }; Note the unless statement modifier to suppress printing the comma after the...

I recently had to extend the aasm states for the latest version of restful_authentication (github) in one of my apps. I removed the "include Authorization::AasmRoles", copied the existing states and events from the plugin and made the changes necessary to support an additional "published" state on my account model. Does anyone have a cl...

I'm finally getting the hang of RSpec after spending a couple of hours over the weekend. Now I'm stuck trying to figure out how to assert that parameters are indeed passed into the controller.

I came in this morning, fired up my app in the same way as usual, and started getting this error. Since then, I have been down every road I can conceive - to the point of removing and reinstalling every piece of ruby/rails software on my machine, including mysql. I have stripped my application down to just the following. require 'ruby...

I'm a bit of a newb when it comes to this stuff. I havn't quite understood whether I should be automatically able to use the below syntax (username:pwd@) or whether the username and p...
I've used straight Mongrel, I've used Mongrel clusters behind Apache, I've looked at Thin, and I'm becoming very intrigued by Passenger. I've looked at Nginx, too. I've looked at MRI, Ruby Enterprise Edition, Rubinius, and JRuby. There are a lot of options, each claiming to be the new holy grail. What is the best option out there for a ...

I'm trying to do Ruby password input with the Highline gem and since I have the user input the password twice, I'd like to eliminate the duplication on the blocks I'm passing in. For example, a simple version of what I'm doing right now is: new_pass = ask("Enter your new password: ") { |prompt| prompt.echo = false } verify_pass = ask("E...
