similar to: Describing a "replaces" relationship within the same model

I posted something about this a week ago wihtout response, but have made some progress since. However, I''m still not getting exactly what I want. OK, three core tables: create_table :reference_items do |t| t.column :title, :string, :limit => 255 t.column :year, :integer, :limit => 4 t.column :type, :string t.column

Alex, I'm trying to think through how binding/unbinding of devices will work with VFIO for platform devices and have a couple of questions about how vfio-pci works. When you bind a device to vfio-pci, e.g.: # echo 1102 0002 > /sys/bus/pci/drivers/vfio-pci/new_id ...I understand that the echo into 'new_id' tells the vfio pci driver that it now handles the specified PCI ID. But

I have a CentOS 5.2 install on a machine with the Marvell nic issue outlined in http://bugs.centos.org/view.php?id=2612. I have a few questions regarding this, what does the # echo "11ab 4364" > /sys/bus/pci/drivers/sky2/new_id line do? Obviously it starts right after but what specifically is the "11ab 4364" part? Also, how do I get this to load across reboots? I have the

I''m trying to do a basic relationship and it''s not working the way it should. The data model is obviously a test database as the fields are minimal. In irb I do the following: >> user = User.create(:name => "shawn") => #<User:0x259ceac @errors=#<ActiveRecord::Errors:0x259c3a8 @errors={}, @base=#<User:0x259ceac ...>>,

Hello, I''m just starting out with both Rails and Ruby, so I hope this isn''t too simple of a question - but I''ve been struggling to find a solution. I''m using the file_column plugin to handle image uploads and thumbnail generation. In addition, I''ve wrapped the image into a polymorphic table so I can have uploaded images associated with multiple

Hola, Please, mira si esta vez funciona: #---------------------------------------------- ID <- c(1, 2, 3, 4, 5, 6, 7, 1, 2, 3, 8, 9, 10, 11, 12, 1, 2, 3, 4, 5, 6, 1, 2, 6, 8, 12, 7, 15, 16, 17, 18, 19, 20, 1, 21, 22, 19 ) Year <- c (1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5, 5, 5, 5, 6, 6, 6) df <- data.frame (ID, Year) df ID <- c(1,

Hola, Antes de nada, muchas gracias por tu ayuda. El código se ha acercado bastante, pero no termina de funcionar porque considera cada captura de un individuo como años consecutivos aunque haya pasado más tiempo entre ellos. Por ejemplo el individuo 4 es capturado por primera vez el año 1 y por segunda vez el año 3, por lo que debería de ser renombrado ya que en este ejemplo en concreto

Dear all, I need to create a for-loop in which I can compute multiple histograms My code is the following : #singlefile includes huge csv file #I want to specify the binsize #I would like to compute in the for -loop the histograms numfiles <- length(singlefile) for (i in 1 :51) { binsize <- -20 :20/2 hist(singlefile(singlefile$GVC[singlefile$new_id==i]], break=seq(),

Hi all I have a very weird case of pci passthrough. I have a machine with 7 network interfaces, all of them intel. Four of them are on one quad giga ethernet device. If I manually unbind the devices and allow qemu to use them, with intel IOMMU working, everything works like a charm. Here's how I do it manually: root@kybrat (x86_64) ~]$ lspci -nn | grep net 00:19.0 Ethernet controller

Hello List, I created a self-referential many-to-many relationship (as described in the book Rails recipe #18), where I have a model that has many-to-many relationships with itself. In this case, it''s person who can become friends. The join table looks like this: mysql> select * from friends_people; +-----------+-----------+-----------+ | person_id | friend_id | confirmed |

I''m a rails newb and have been Googling about this, but I''m still stumped. Not showing everything here, but basically it should be a pretty common setup so I''m sure others know what I''m doing wrong. - A meter can belong to many meter_groups - A meter_group can have many meters. - A user can ''subscribe'' to viewing a meter_group (Subscription)
