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

Hello happy Railers, I used to develop with a local out-of-the-box Apache and load times were pretty slow (like a few seconds each page). "Well, it''s the price to pay for no compile / cache / etc..." I thought. Nonsense.

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.

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

I''m trying to open a new window for printing a form from a link. I want to display the contents of the form for printing. I can get the popup to work, but am wondering how to get the contents of the form from the parent window, using RJS.

Hi, I have a model similar Basket shown below. If customer_type is set then it should also set customer to nil. Likewise, if I set customer, it should inspect the customer_type attached to the customer and set accordingly within Basket. However implementing it as below doesn''t seem to work. Am I missing a better way to achieve this? I had also considered using a before_save
