similar to: Instance variables versus local variables

Hi, Sebastian Kanthak of the file_column-Plugin wrote once: "is the photo object inside a local variable or an instance variable (e.g. photo or @photo)? url_for_file_column only works with instance variables, like all other active record form helpers. Could this be the problem?" So I''m using file_column in a partial, e.g. <%= render (:partial => "product",

I have the following in my functional test file. class UserControllerTest < ActionController::TestCase fixtures :users def setup @controller = UserController.new @request = ActionController::TestRequest.new @response = ActionController::TestResponse.new @invalid_user = user(:invalid_user) @valid_user = users(:valid_user) end def test_login_success

i have these two really similar methods in my addressbook controller. def edit_company @company = Company.find(params[:id]) if request.post? and @company.update_attributes(params[:company]) flash[:notice] = ''Company was successfully edited.'' redirect_to :action => ''show'', :id => @company end end def edit_person

This issue has been discussed before (http://www.ruby-forum.com/topic/ 125392) and after spending a while debugging through this, I still don''t have a solution. Lets try again? I have two controllers, SomeController and Admin::SomeController. When SomeController is loaded first (which happens under spork, found out by editing ActiveSupport::AbstractController) I get warning: toplevel

Code sample: class SomeController < ApplicationController before_filter do |c| add_crumb "Blah", "/blah" #breadcrumbs plugin redirect_to :controller => "foo", :action => "bar" unless c.send (:has_package?) end # Rest of the controller... private def has_package? # A bunch of logic work to check to make sure # somebody''s session contains

Hello. When trying to sort a folder by thread (with pine4.61), I get a sig11. The mailstore is Maildir, indexes stored in /var/indexes/%u. The syslog on the server shows this: Nov 29 11:37:55 olan dovecot: IMAP(kowalski): Corrupted index cache file /var/indexes/kowalski/.INBOX/dovecot.index.cache: record points outside file Nov 29 11:37:56 olan dovecot: child 14344 (imap) killed with signal 11

What would be the best way to create a form select dropdown box and upon "submit" have it directly go to a controller method view? I have something that somewhat works, but I think there is probably a much easier way to do it. As of now, I have the dropdown list which when the form is submitted is handed to a controller method which basically I have my dropdown box: <%=

Hi, would like to use LLVM as backend for a compiler. One of the features I would like to implement is segment based addressing for position independent data. For some it may sound strange, for others the opposite. No need to write complex story. Imagine you have a custom alocator that manages an area of 1GB of memory. Your application uses a custom allocator to allocate memory inside this area,

I am trying to subit some xml data over https to access an API. My code so far seems to generate a very non-helpful error in the guts of the net/http library. This code produces a NoMethodError for nil.strip" require ''net/http'' require ''net/https'' require ''uri'' url =

I''m heading out of town, but had a quick thought I wanted to share. Rather then using ambiguous named request helpers in controller specs like "do_request", I''ve been using more readable helpers like "post_create". For example... describe ProjectController do def post_create post :create, ... end before do end it "creates a new

Dear Members, I am working with 6-dimensional Student-t distribution with 4 degrees of freedom truncated to [20; 60]. I have generated 100 000 samples from truncated multivariate Student-t distribution using rtmvt function from package ?tmvtnorm?. I have also calculated mean vector using equation (3) from attached pdf. The problem is, that after summing all elements in one column of rtmvt result

Out of curiosity, I''ve seen the following fail: module Admin describe MyController ... end end But this works fine: describe Admin::MyController .. end Why? Scott

Dear OpenSSH developers, I was looking at the fail2ban project and had an idea that instead of parsing log files it could be possible to notify interested parties (like fail2ban) via (for instance) D-bus about a failed login attempt. Other application could also use this protocol to notify about suspect behaviors. A central functionality will allow for other (new) projects to integrate

Hi all, I've recently decided to take a look at Theora for the first time. The 1.1.1 release compiles fine, but the compiler generates a fairly large number of warnings about "suggest parentheses around + or - inside shift". I've had a look at a few of these and sometimes it isn't obvious what is meant to happen. I guess the code is all correct though as I'm sure

does anyone know much about resizing different versions of images with file_column? i tried it and everything works fine, but my question is can you do more than just make sizes with a version of image? i''m working on a photo album and i would like to resize the image to a medium size, but create a thumbnail as well and crop anything left to make the thumbnail a perfect square. --

Hello. I am currently testing dovecot (0.99.10.8, Debian woody from backports), with the maildir storage. I have noticed that when I use the mailutil tool from uw-imap distribution to transfer my IMAP mailboxes from our current server (uw-imap, mbx format) to the dovecot one, the mails arrival time are apparently lost. I can see this in Pine, using the Arrival sort: the mailboxes on the

Greetings all, This is the first release of the SuperImage plugin. The idea is you upload images to the database, and then pull them out at any size you want. Combine this with caching and it will stay light and fast. More info and instructions are here: http://beautifulpixel.textdriven.com/articles/2006/04/27/superimage-plugin-making-resizeable-uploaded-images-easy svn:

Hello, I have a win32 DLL library, which I can't decompile, and can't get it's source code, but which I'd like to use in my Linux program. I wondered about making a win32<->Linux interface to use this library, using ready-to-use wine libraries. Is it possible, using wine libraries, to have access to functions from this DLL? If yes, can you tell me how? Thank you in

Has anyone been able to get script/server to successfully use lighttpd on a Windows box? When I try to start the server I get: PROBLEM: Lighttpd is not available on your system (or not in your path) So then I add "C:\lighttpd\sbin" to the path for the console session, and it still fails with the same error. If anyone has some success with this I sure would like to know. Webrick

I''m building a users web service (direct dispatching) that will (I hope) allow several other applications to manage the same pool of users. Plus it will act as a single-sign-on solution for what I''m doing. But I''m having difficulty accessing the UserAPI. Here''s what I''ve done so far: $> rails usermanagement - "usermanagement" is the
