I have a form_remote_tag that calls a method to print out a csv file for download. If I tell the form_remote_tag to update a div the data comes up in that div, but otherwise I can''t get the browser to acknowledge the sent file. >From view: <%= form_remote_tag :url => {:action => "csv_dump" }%> <%= submit_tag "Download Complete List" ,:name

I''m trying to write an interface for editing many-to-one relationships with AJAX. Picture the to-do editor in Backpack (and, to a lesser extent, Basecamp) and you''ll have a good idea of what I''m trying to do. I''ve almost got everything working: the ''edit'' link hides the stored data and replaces it with a form, and the data is updated in the

"Well, it''s the price to pay for no compile / cache / etc..." I thought. Nonsense. Yesterday I installed SCGI, and now I''ve got the best of both worlds: rails development env uses my very latest modifications, while SCGI ensures I

I am trying to create a record with association. Within the create method, I would also like to pre-populate dependent (has_many) records from a template in the database. The child records are <u>mysteriously rolled back </u> if I insert them in a loop. If I try to insert a single child record, it works.I have read the books and tried to google my way out of this but am at a dead

I think I must be doing something wrong... when a form returns params to the controller, empty fields appear to be returned as blank, not nil. so what''s the point of an :allow_nil=>true setting on a validation? it fails because blank is not the same as nil. i would expect either returned empty fields to be nil, or :allow_nil to really be :allow_blank. otherwise i have to do a search

Hi, I''m looking for a way to extend one of my models to allow some level of abstraction between what goes into it and how it is stored. For example, say I have a Product and I want to set it''s price. A person using the website will type the price in euros. Internally, I''d like to store the price as an integer value of cents. I can currently do this with some ugly code

I have the following models: User, Registration, Event. User has_many Registration, Event has_many Registration, and Registration belongs_to User and Registration. So far, so good. There''s a registration deadline on a Event though, a few days before the Event occurs. So, I have this: class Registration < AR def before_create errors.add_to_base("Registration deadline has

I''ve been working with the problem that Joe Hosteny has been talking about on this list and on the tickets he''s posted (http://dev.rubyonrails.com/ticket/1196) and have come up with a tentative solution that I''d like to bring up here. What if we use a "conditional" parameter in the validates_* methods? Here''s how it would look like in practice:

I have two models, A and B, related to one another by a many to many association and I want to validate an object of model B as it''s being added to the association based on both its own attributes and attributes of the particular object of model A that it''s being associated with. I''ve realized that I can''t do this if the association is represented by a habtm
