Multiple (AJAX) Observers on the Same Field and MSIE
I have been using multiple observers, i.e., observe_field(), on the same input field and relying on them to execute in the same order that they appear in the page. This has been working fine in FireFox, but it does not seem to work in MSIE; the requests come in and are processed in a different order. Now, I''ve always been a little hesitant about using this technique, but it always

Non model cascading selects
In my model I have a city_id. ON the form I am using a cascading select to select the state, which then does a remote_submit to get the list of cities (and hence the city_id) for the selected state. The problem that I am having is that if I make a selection, hit SUBMIT and validation fails, the original selected state/city is now reset (ie, the values aren''t saved). Since they

Assigning to the foreign key on a belongs_to association
I''ve encountered what seems like an odd omission in the behaviour of belongs_to associations: if you assign to the foreign key attribute, it doesn''t update the associated object (or mark a previously loaded one as stale) until you explicitly save or reload it. Let''s say we have a Company model, which belongs_to :city : >> torchbox =

Question About Rails.cache and find method.
The DB load on my site is getting really high so it is time for me to cache common queries that are being called 1000s of times an hour where the results are not changing. So for instance on my city model I do the following: def self.fetch(id) Rails.cache.fetch("city_#{id}") { City.find(id) } end def after_save; Rails.cache.delete("city_#{self.id}"); end; def

What I am looking for is an explainantion of the rules/requirements for table/index/coulumn names with RoR.
