Does anyone know of a fix for the issue with prototype and replacing table rows in IE? render :update do |page| page.replace "row_#{params[:id]}", :partial => ''wireless_request/wrequest'', :locals => {:wrequest => @wrequest} end This ends up making IE throw an "rjs error [object error]" Searching around I found a couple of posts about

I have a rails application that runs on multiple mongrels and I would like to make the log files non-interlacing. Are there any logging modifications/other loggers out there that I could use to create process safe logging? Thank you, Matt Margolis

I have a User class with a field called admin which is a boolean that determines if the user is or is not an administrator. I want to make it impossible for the last administrator for an account to be removed from the system. I need to protect against this both when deleting a user and when editing a user as you can revoke a user''s administrator privileges via a form. User

I am working on writing a search method where a user can type a string of words and I return all the objects that have fields that match all of the words in one or a combination of fields. Person first_name last_name Pet name Person has_many :pets I want to write some SQL so that if I search for "Tony AAAA" I will get all the people who have Tony and AAA either in their

Is there any scalable alternative to iterating all the records of a certain model? #find_all seems to load everything into memory. With 500.000 records it will be a swap storm. Pedro.

I am working on an application where users sign up for one of several plans. Each plan has a different monthly fee. There is no long term contract but I would like to bill the users automatically each month unless service is canceled. What credit card gateways would you recommend for use with a rails application? My criteria in order of importance are 1. API that will let me work in

I am using the drop shadow technique described at http://www.1976design.com/blog/archive/2003/11/14/shadows/ to give several of my divs drop shadows. That part works fine. What doesn''t work so well is when I try to BlindDown a div in Firefox and it ends up ignoring the content below it and just overlapping it. In IE this problem does not occur. In Firefox the overlapping does

Hi, I have a Product and a corresponding Keyword (1:1 via belongs_to and has_one). I want to ensure, that two attributes (:name) of the two models alway stay in sync. What''s the easiest way to accomplish that? I did play around with before_/after_save hooks and with AR::Observers but in the end I''d always get infinite recursion... Thanks, Timo

It would appear that using :include on a model that has_many with an :order on another model makes it so that the order is ignored. Is this supposed to happen? Strikes me as odd behavior. For example class Farmer < ActiveRecord::Base has_many :cows, :order => ''position'' end class Cow < ActiveRecord::Base acts_as_list :scope => :farmer end If I do

I want to host a rails app at mydomain.com/railsapp. For technical reasons I have to leave mydomain.com on apache. This means that I need to tell apache to proxy only requests for mydomain.com/railsapp to lighttpd. I have deployed in a situation like this before around a year and a half ago but it was a real pain. Lighttpd and rails have matured a lot in the year and a half since I did

I am looking for some advice on how to make a date select display only valid days of the year. The standard date helper allows for you to choose 31 days for every month of the year. Since not all months have 31 days this can lead to invalid date entries for scheduling. I am thinking that an approach where I have a drop down for month and then use AJAX or normal client side javascript to

I am trying to create a sortable list that is submitted not with an AJAX call but by a standard form submit button. Right now I have def reorder_group_members @group = Group.find(params[:id]) @group.group_members.each do |member| member.position = params[:memberlist].index(member.id.to_s) + 1 #I get a nil error for this line. It would seem that params[:memberlist] is not

My .rjs file page.visual_effect :BlindUp, "people", :queue => ''front'' #first action page.replace_html "people", :partial => ''person/person_compressed'', :collection => @search_results , :queue => ''end'' #second action, after first is done page.visual_effect :BlindDown, "people" , :queue =>

I am currently developing an application in which two users exchange goods and money in an escrow like environment. Buyer has some money and wants an item that Seller has. Buyer does not want to pay Seller until Seller ships the item. I am unsure of how to best handle the payment part of my application. Buyer''s money eventually has to end up at Seller and my company would like to

I am building a rails application in which it would be pretty cool to have certain actions that occur on key presses via some javascript doing a remote action call. I was hoping that someone who knew a little bit about using javascript to capture key events and the different browser issues I might encounter could share some knowledge. Which browsers work well for this sort of thing? Can I

I have action caching setup for several actions of an application but I want the caching to only run for my administrators and have all other users see non-cached pages. Is there a way to do this? Perhaps something like passing a block to caches_action or setting some sort of flag in my authentication method? If this is not possible with action or fragment caching does anyone know of a

In an integration test that I am writing I want to do something like def test_my_page get "/rails/someaction" assert_response :redirect follow_redirect! assert_url => ''http://www.somepageoutsidemyrailsapp'' end Is there any way to do something like ''assert_url'' and see if I was redirected to a page outside of the rails

I have two before_filters for a few of my controllers. They are running my own methods authorize and admin_authorize. authorize is called on just about every action to make sure that a user is logged in. admin_authorize is called on about 80% of the actions and is used to make sure that a user is an administrator. If a user tries to access an admin_authorize protected action without being

Let''s say that there is a web application which comes in several different plans. Each plan has a different number of users and content items allowed for an account. Obviously we can allow the user to upgrade to a higher level plan by just increasing their limits but how do we handle downgrades? If the user is only allowed x items on the downgraded plan and they currently have

I am having trouble getting error_messages_for to work. My controller(relevant parts) looks like def configure @account = session[:account] @user = User.new end def add_new_user_to_account @user = User.new(params[:user]) if @user.valid? session[:account].users << @user end redirect_to :action=> ''configure'' end end and my
