I have an e-commerce site and users check out with a form. The results of that form are sent to a "confirm your order" page via POST. I take great pains to NEVER store the full credit card number on my server--just the last 4 digits. I was very surprised to find that by default Rails will record POST requests with parameters in the production.log. And those parameters

I have a form with a text area. I want to have an observer watch the text area and update a div with the running count of characters in the text area. I tried "onchange" but that doesn''t update until you leave the text area. I was able to get it working using AJAX, but it''s silly to make a needless round trip to the server, when the page already knows

Hi, I am new to ruby and to rails, but I like what I see so far. I have been working on a web app in java (servlets and JSPs) that, based on a request from the user, kicks off a thread in the background to perform a task (puts messages in an MQSeries queue). The thread object is stored in the session and I then allow the user to control the task from the browser(like stop it). Is the same

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

I, like many of you, have been searching for a good way to handle running long processes in Rails. So I rolled my own solution. I really want feedback! (I''ve tested this on very simple hello world examples, so don''t use it on anything production yet) . Grab the plugin: http://opensvn.csie.org/rails_cron Here''s the README: OVERVIEW ======== RailsCron is a way to

I found a tutorial for creating classes using generic functions ? S3 way ! It was short description so I couldn't grok in full its usage ... So far so good, what i currently do is something like this : Blah <- function(data,...) UseMethod('Blah') Blah.default <- function( ...... ) { self = .... class(self) <- 'Blah' self } Blah.some_method <-

I want to be able to write a script in Ruby which regularly consumes an XML feed from a fixed source, re-formats it, produces a large file for web delivery, and updates a database with the contained information. It''s simple - just running a script from a cron job, and some basic data manipulation... But I''d prefer to use the Rails database mapping constructs than roll my

I updated RailsCron to fix some threading issues with ActiveRecord. Please update if you were on 0.2.1. Also, I am still working on a good unit test strategy (its tricky because I would think that the tests must occur over a lot of time), but haven''t had/made time to give it its due. If you have suggestions, please let me know. -- Kyle Maxwell Chief Technologist E Factor Media // FN

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

I have a method in a controller that invokes a render :partial => ''some_partial_view'' In that view, I''m trying to access a method defined in a model, like this; <% for view in @an_array %> <% local_var = view.some_method() %> <% another_var = view.a_column_name %> etc.. I am getting an undefined method error but the model is accessible

Hi everyone, I''m at the end of my rope on this. I can''t get pagination to work with anything but a standard find on a model. If I try to do a search and customize the pagination, I get lots of different variations. My thought was to have the list action do what it does, but to pass it a list of search conditions from the search action. So, if search determines that we need

I have an app that requires me to define a class variable (actually an array) in a controller and then access it from within a view. It seems that the class variables aren''t working right. Here is an example of what I''m trying to do. class DisplayController < ApplicationController @@thumbnail_array = Array.new ... def some_method @@thumbnail_array = SomeModel.find_all

I''m using the rescue_action_in_public example from the Agile book to handle errors and email serious ones to me.

Hi, I have a controller where I access a singleton class that I use to connect to a DRbprocess DrbConnector.instance.some_method I notice that on every request, the constructor is called so it is making a new instance of this singleton. Is this normal? Thanks, Curtis

Hi, I wonder if there''s an easy way to access the associated Model class from its Controller. Something that would allow me to write snippets like the following: class PeopleController < ApplicationController def some_method person_model_class = self.some_method_to_retrieve_the_person_model_class() end end Cheers, Marco -- Posted via

I''d been ignoring this error message in my log for a while: ActionController::RoutingError (Recognition failed for "/robots.txt"): I had never touched robots.txt.
