Heya everyone! I am quite new to Rails and I am reading AWDwR. I am at Task E "Check Out!". I understand it quite well, but I have a problem with the last playground exercise: Add a Table which contains the payment types. All goes well, but I am not sure whether I should use has_many or has_one(as in the Playground wiki at http://wiki.pragprog.com/cgi-bin/wiki.cgi/PT-E-3). I use the

Hi everyone, I would need to know if RoR follow any policy for version naming; I mean, something like linux´s kernel does or similar. For instance, kernel uses numbers separated in groups by dots (i.e. pre 2.6 - AA.BB.CC). These groups mean differents fixtures, bugs fixed... I will start a big proyect from scratch with rails and I want to choose now a standart to use and avoid future problems

My application accepts a form to create multiple large(100''s of MB) temporary files and then zip''s them up to send off to a user. I have the files constructed, and the zipping working. The problem is that if I use send_file to send the zip off to the user, I cannot delete the file afterwards as it seems send_file forks off another process and deletes the file before the

Hey all, i''m rather new to rails and was curious if ActiveRecord implemented anything like is_active where the delete functions would just mark records as inactive, vs deleting rows. (similar to created_at, etc). I need a history of transactions, and this is how I would code in other languages. Any advice? Is there are smarter way to implement this? Thanks in advance! -- Posted via

Let''s try this one... I have Apache 2.0.55 set up and also have Mongrel set up. I have Radiant set up running under Mongrel, and have Apache proxying to the Mongrel instance. That all seems to be working fine. I thought I''d modify the settings a bit to let Apache serve up the static files - images, stylesheets, etc. I have it set up, and am not getting any errors. However.

I''m trying to run an external Ruby script from my Rails app. To do this i''m using this function def fork_with_new_connection(config, my_class = ActiveRecord::Base) pid = fork do begin my_class.establish_connection(config) yield ensure my_class.remove_connection end end Process.detach(pid) end Then, within my controller I do this:

Hi: you know the way the google and this forum presents dates? How it''s measure from the current date/time and presents nicely as "39 minutes ago", 2 days ago, etc.? Has anyone done a gem or other library object that I can get to do those types of dates? Thanks so much in advance! Mike -- Posted via http://www.ruby-forum.com/.

Hello all, I am running a blog system which has its "/" (home page) cached like this: class ApplicationController < ActionController::Base before_filter :index_cache_expirer, :only => [:index] caches_action :index so the site''s top page is caches for 60 seconds in my case (index_cache_expirer is a home-made function to expire) on the site, there is also a

Here are a few suggestions, wondering what others thought: When you generate a model for a DB table, it would be nice if the model.rb contained the DB schema (kind of like # commented out schema) right in the model file. This would make reference WAY easier and put all of the DB stuff in one easy file. Thanks. also nice, of course, woudl be for rails to try and ''guess'' the

I need to create a small hash of values that persists across requests in Rails. I cannot store this information in the database or filesystem and only want to do it in memory. I was looking for a simple solution to implement this and read somewhere that memcache is pretty much overkill. This app is only running on one server so putting in memory should be just fine. I''m very new to

One of the areas where I think Rails goes too far is in many of the helpers that (AFAICT) do nothing more than change the syntax used to write simple HTML tags. link_to and many of the form tags come to mind. For me, these helpers aren''t that helpful. I find the HTML much clearer to write and read, I don''t see any added value in the overhead costs of using code to

I''m just starting to learn ruby and i wanted to set some projects for myself the 1st of which is a poker clock running online, but before i start trying to do it i would like to know if it''s possible. I dont want to waste my time if it''s not possible at all. Thanks. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You

My latest stupid web trick, built, with love, in Rails: http://wordie.org Make lists of words. See who else likes the same words. Basically, it''s a dating site. Built on thanksgiving while half-watching football and launched yesterday. In other words, half-baked, but I thought some of you might find it mildly amusing.

What do you guys use for design and modeling (and don''t answer pen and paper, because I use those to, they just don''t look so good in a project report ;) ) I have tried stuff like UMLet (free), Altova UMLsomething (pay), dia (no comprende ;) ), NetBeans UML (slow). But none worked just the way I wanted them to. Any suggestions? Christian...

Hello guys, I''m trying to validate the input of an integer from a form, here is a bit of code: This is the definition of the offending column in the migration: t.column :position, :integer, :default => 0, :limit => 3, :null => false And here is how I try to validate it inside de model: validates_length_of :position, :within => 1..3 And this is the exception I get when I

I''ve seen discussion on this topic in the past, and was wondering what people''s feelings were in regards to the more recent releases? Mainly, could it be possible to build a web application on the scale of, say, Amazon, or deal with similar bandwidth and load requirements as an iTunes would? It may be unfair to expect that much, seeing as these are some of the largest around,

Hi all - Can anyone tell me why stylesheet_link_tag defaults to :media => ''screen'' instead of ''all'' (or just leaving it out alltogether). Seems odd since I would think by default I''d want my page printed out the same way it looked on the screen... Anyone know why that default was chosen? -philip

Hi all - I was wondering if it''s possible to serialize capistrano tasks (ie. one after the other on each server instead of simultaneously)? The reason I''m asking is that we deploy to about 20 servers and when running ''cap deploy'' it hammers are SVN server while it''s doing it. So, if it could serialize the ''svn co'' portion and then

Hi all - I was wondering if there''s a plugin out there that will make expire_page work across multiple servers? That is, I''ve got two servers A and B behind a load balancer. If I cache a page eventually it will be cached on both servers. I''d like a way to expire that page and have it happen on both servers. Perhaps some integration with backgrounddrb that could
