Hi Guys, I just realize that on the API documentation the code snippet is overflowing off the screen. Is this an intended behavior? Or who should I contact to get this one fixed.

Hey guys, is there a validation that essentially acts the opposite way of "validates_presence_of". That is, the attribute in question must be nil, or blank, non-existent.

..."some other custom message" obviously, it throws an exception. So the question is, in Rails 3, how to you give a simple custom message? Do I need to go through and set up a custom validation class for each validation, just to show a different message?

Is there any way to clear what''s in there? This happens any time flash[] is in my code. It can be setting or reading a value. I''ve tried commenting out all uses of flash in my code to get a few different pages to load, thinking this would clear the values, but no luck. If I get into the debugger, a p flash or pp flash will give a ''Stack level too deep'' error

I want to write a validate routine to check to enforce that a position must be unique in a category. (In another category, it doesn''t have to and shouldn''t need to be unique.) I write this code which works happily for new items: def position_in_category_not_unique @items = Item.find( :all, :conditions => [ "category_id = ? AND position = ?", category_id,

If I don''t want xml results but only html can I omit respond_with in some actions?

Restful_authentication has several git branches, none of which appear to result in a working installation. All of them leave me with "could not find generator authenticated". With Devise: "could not find generator devise"
