Apparently a scaffold creates at least one instance variable for views to use, and if I override the scaffold then I must also explicitly create that instance variable for the view. I''d like to know exactly what work is performed by the scaffold so that I can know this when over-riding the view. (OR, is it that the controller makes these variables available by default?..) EXAMPLE:

This is of course disallowed, which I discovered only after nearly completing my spanking new ajaxified UI. What is the motivation behind this, and what is the best workaround? This UI does a scriptaculous drag-and-drop of items from a first div (div1) over to a second div (div2), which triggers the contents of div2 to be updated to reflect the drop. No prob, thus far. But then the

I am seeing a curious anomaly with the inspect method. It displays one of the objects in a way I don''t understand. I''ll use the Recipes example to illustrate. First, I''ll describe the recipes table, then show how the @recipe variable is being created in the controller and passed in to the show view, and then show how I''m using the

I implemented a prefix search using the following custom paginator: @performer_pages = Paginator.new self, Performer.count, 25, @params[''page''] @performers = Performer.find( :all, :conditions => ["Name >= ?", params[:prefix] ], :order => "Name ASC", :limit => @performer_pages.items_per_page, :offset =>

...or my ineptitude? I found that the following is always checking the last ''things'' button regardless of the value of query.table: People:<%= radio_button_tag("query", "table", "P") %> Animals:<%= radio_button_tag("query", "table", "A") %> Things:<%= radio_button_tag("query",

I searched this site on Oracle && MySql, nothing came up, so perhaps this is a new topic for this forum. I''d like to access two databases from the same application simultaneously (well, more precisely, in rapid succession, calling one first and then the other, as any "joins" will be done in the application code). One database is in MySql, the other is Oracle.

I need to have a table related to itself via a join table. Will HABTM support this? That is: class Recipe < ActiveRecord::Base has_and_belongs_to_many :recipes, :join_table => "recipes_recipes" end More importantly -- how does RoR support MULTIPLE self-joins? I.e., to relate the table to itself via multiple join tables. SFAIK, HABTM won''t support multiple

I''m experimenting with Rails on the Recipes example first before I dive into applying it to my intended application. I''m exploring which will be more work: to rename all the primary id''s in the legacy database, or to work around the fact that the primary id''s are not called ''id'' within RoR instead. I''ve been successful in using a
