I want to be able to utilize the acts_as_state_machine transition methods which are auto-generated (e.g. event!).. but I don't want it to save right away. I'm updating the state as part of another set of operations, and so I don't want to be doing double saves. Is there any way to trigger these event methods without a save right afterwa...
I am trying to find a way to let me dynamically create a regexp object from a string (taken from the database) and then use that to filter another string. This example is to extract data from a git commit message, but in theory any valid regexp could be present in the database as a string. What happens >> string = "[ALERT] Project: Rev...

I'm using this REST web service, which returns various templated strings as urls, for example: "http://api.app.com/{foo}" In Ruby, I can then use url = Addressable::Template.new("http://api.app.com/{foo}").expand('foo' => 'bar') to get "http://api.app.com/bar" Is there any way to do this in Python?
