super global dummy method for gettext + rails 2.2

My application doesn''t need any i18n support right now and this way i figured it would be very easy to integrate gettext later. Just setup the plugin and go. So I need a method called _ which is available in alle models,

params vs @params
Is there a difference in the way that params[] and @params[] are handled? Is the ''handling'' done by Ruby or Rails? A pointer to the relevant documentation would be sincerely appreciated. Or just an answer would be ok too ;-) Thanks, Bill -------------- next part -------------- An HTML attachment was scrubbed... URL:

BigDecimal + Float => Float?
I was just playing around in irb and noticed that while BigDecimal + Integer => BigDecimal, BigDecimal + Float => Float. Is there any reason for this? It seems inconsistent and means you have to check the class of any number you add to a BigDecimal, which looks very un-Ruby-like to me. Ashley

Ready to call this a bug
I''ve been trying to get a handle on AJAX today and am ready to call "BUG!" I started with the code from Curt''s "AJAX on Rails". It used <ul="my_list"> and <li> and worked fine.

If I run them with an empty database, it runs the first three, then halts. When I look in schema_info, the version is 3. If I run db:migrate VERSION=7, then it runs through the remaining 4 migrations, and the version is 7 in the DB.

Managing migrations
I have a migration "x" that when it runs self.up it adds a new column to a table, and of course when self. down is run it deletes said table... After I ran this migration I continued to work and in the process added a couple other migrations. After a while I realized that the column migration "x" created was a mistake and I no longer need it. So I ran rake db:migrate:down

I am able to display all the images once I get them all, but that causes an unacceptable delay for my user. One approach I am trying is, from my controller, set an @image variable, and then pass in a block to the model that retrieves the
