How to apply an effect to a link_to_remote :update without using evaluate_remote_response?
Hey all, I''ve been trying to apply a slide-down (or highlight) effect to a "New card" link on my application. Because the item is *new* and I''m simply updating it at the top, I can''t know what the div id is before I make the request. link_to_remote :complete => visual_effect(:slidedown) doesn''t do what I want it to do. My current solution is:

weakness of helper?
Hi , It comes to me that helper has some weaknesses: 1) It is hard to test . No easy way to write test code for it. (or Just i didn''t know?) 2) Not easy to reuse it on other controller/view/model. it looks like to that putting the helper code into a model (a fully helper model , or a mixed model) is good practice. However i agree that some html intensive

Hi, I have a utility function repeated in both my helper and my controller. Not DRY. I have this repetition because other functions in the helper and in the controller both use the utility function.

MVC newbie question
All, Is it possible for a view to call back to a controller method? If so, what is the syntax? === details I have a list view that I want to filter out inactive rows based on several table fields being zero, old, etc. It would seem I should create a "filtered" method in the controller (which I have done). Then invoke if from the view like: for row in @rows continue if row.filtered

Global Method Declaration?
Is there a place where I can put a method that can be accessed in both views and controllers? Here''s the situation, maybe someone can suggest a better way to go about this: I created my own custom login system with email verification and user roles (basically, I tinkered around with SaltedHashLoginGenerator until I finally gave up and wrote my own). One role, of course, is an admin

extending rails via /lib - problems
I wanted to group some functions which I use in some models in one place. Controllers have application.rb and views have helpers but I couldn''t find anything about models. Using the /lib directory seemed to be the only way. Alright... so I have something like this: /lib/code.rb class ActiveRecord::Base def method_a(n) ....... end def method_b(n) ........ end end

state_models plugin and file_column?
I was looking at Kyle Mawell''s extremely nifty-looking StateModels plugin http://www.kylemaxwell.com/articles/2006/02/06/fun-with-single-table-inheritance and before I go down the road with it, I was wondering if anyone has used it with file_column. The way file_column deals with an uploaded file -- by storing it to the filesystem in a path that employs the model name and id --

conditional validation
Hi, How can I validate user info under certain conditions? For example, I just downloaded a plug-in that allows me to validate phone numbers, but what I would like is to only validate the phone number if it is not blank and if the user_type_id field is equal to one. How can I achieve such a validation in my user model? Thanks, - Dave --~--~---------~--~----~------------~-------~--~----~ You
