If you don''t need to query a database by a field, you don''t need the full overhead of a field type. To give your users abstract data, let them enter keys and values into fields that expand forever, and then AR will serialize them. They go in as YAML strings of your hashes. -- Phlip --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I try, but have an error. Now I have table in database with "e_key" and "comment" fields and standard new.html.erb (built by scaffolding). So actually I have two question: 1) How dynamically to add empty fields on page (by click button)? 2) How to collect all data from all rows and put they into database?

You will need Javascript for this sort of thing as Ryan Bates points out in his screen casts. There are many ways to do it, e.g., RJS templates or unobstrusive Javascript. Next in your create action, you will have to loop through the newly added rows to the database. It sounds simple, but it isn''t if you are a beginning Rails programmer. You may want to get a bit more experience with Javascript/Ajax before trying this. However, if you must, lookup the multi-model update recipe in Advanced Rails Recipes Book contributed by Ryan Bates and just exclude the "one" side of "one-to-many" relationship.
