Greets to the list! I am aware that this topic has been discussed several times. And I've read quite some related posts [1]. Yet, can't seem to give a solution to my problem.

If there''s a better way (the Rails way ?), I''m all ears

Hello everyone, I have another question related to a legacy schema I am working with. Do dynamic finders work with legacy schemas in general? The schema I am working with uses hungarian prefixes for column names. For example fOpen is 0 if a bug is closed and 1 if it is open (type smallint). When I try @bugs = Bug.find_all_by_fOpen(1), I get the following exception: undefined method

to wrap each instance variable of an ActiveRecord object between "<td>" and "</td>", is there a way to "loop through" them, at least in the debug mode, no matter there is getter methods to get them or not, or at least the ones with the getter methods? Such as <% @stories.each do |s| %> <%= "<tr>" %> <% s.each_property

Hello There, As a new comer to RoR, I started to follow the article http://developer.apple.com/tools/developonrailsleopard.html. In short you create to entities and one one-to-many relation linking them. Everything was good until the establishment of the relation. I am unable to go any further than "Linking Models Together" : I can create the "vendors" mentionned in the

Let''s say I want to find out what column names exist in two tables, table_a and table_b. One way I''ve been doing this is using ActiveRecord and the column info it returns.

Hi all, I wondered if the following is implemented in ActiveRecord: I have three tables: "products", "properties" and "product_properties" the products table holds base information for the product, like product_id, name etc. >> Product.column_names => ["product_id", "name"] the properties table holds extra "columns" for the

Hi, I''m trying to create a "runtime-generic" ActiveRecord class, It means I don''t need to know the table or database, before I create my program ruby-rails.

Hi, I''m a newbie in both Ruby and Ruby on Rails. I finished the Ruby on Rail Tutorial on Todo list and it was great. But, now I''m trying to understand the logic behind it, that is something that is not obvious on how each one of them ties together. Is there a flowchart that shows how the inner working of Ruby on Rails? In another words, let''s suppose we consider the
