问题 I am using the Koala gem to interact with the Facebook API. In order to connect to the API, I need to pass my cookies to Koala.

How do I get at cookies from within a model? 回答1: Models should not be aware they're operating in a web environment.

问题 Preface: I'm using devise for authentication. I'm trying to catch unauthorized users from being able to see, edit, or update another user's information. My biggest concern is a user modifying the form in the DOM to another user's ID, filling out the form, and clicking update. I've read specifically on SO that something like below should work, but it doesn't. A post on SO recommended moving the validate_current_user method into the public realm, but that didn't work either. Is there something

问题 When running the initial scaffold command, it auto generates a form for you based on your model. Is there any way to rerun this when you are generating a migration?
