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

Sharing function between helper and controller
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.
Where do I put this function so that both the helper and controller
can access the function? Mayber there is a different solution?
Thanks,

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

Define methods for controllers, helper AND models?
Hi all
I know that I can define methods in e.g. the application controller and
make them available to the helpers using helper_method(), but how can I
make them available in the models?
I have for example the following method, that I want to be able to call
from any model I wish...
def ApplicationController
helper_method :member
def member
session[:member]
end

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

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)

ActionController <-> ActiveView code access ambiguity
Hi All!
This is not a problem in general but i''ve just missed the point.
If my application has a global state, which i have to use both
throughout ActionController and ActiveView, then, where to place that
state?
E.g. if I do this:
class ApplicationController < ActionController::Base
protected
def authenticated?
!user.nil?
end
end
then I can''t use that from any

When to use Mutex::synchronize?
I have a simple question when to the synchronize method in the Mutex
class.
Now that backgroundrb has allow_concurrency = true there is no need
to synchronize database calls in threads.
The question I have is lets say I have a simple method in my worker
as follows:
def some_method
SomeModel.find_all each do |obj|
obj.some_count += 1
obj.save!
end
end
It accesses the database, but

Ruby class variables and access from view templates
I have an app that requires me to define a class variable (actually an

Call an helper method from a controller
Hello, this have been debated few times in the forum but I didn''t found
a satisfying solution : my problem is very simple, I have few methods
dealing with cookies that are intended to be used in controllers and
views.
Let say I have the read_cookie() method. Because it deals with the
response object putting this method in the /lib directory doesn''t fit
nicely because I

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

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
