Hi, I''m doing my first plugin, based on attachment_fu structure. Here''s the code: http://pastie.caboo.se/200797. The problem is that the meta_tag method doesn''t seem to be overwritten.

I am relatively new to RoR and Ruby for that matter. A few questions for the pros: Question 1: In the 5min ajax video the presenter uses <%= yield %> in his layout. In the agile book, @content_for_layout is used. Since, yield is an actual Ruby construct, is it more efficient and preferred? What is the difference? Question 2: Links are often of the form :action =>

I am a little confused about the best way to work with date_select. I see that in my views it generates a simple input form that allows for the entry of year, month and date information. If I just leave it at that, great! But what if now in the controller, I want to work with the date information. I actually want to take the user input date and compute a new date some number of days in the

I want to add a custom validator in one of Model. For example Rails has inbuilt validation methods like validates_uniqueness_of, validates_presence_of .
