GiT and Edge/Trunk Rails
I have a sub-application project that I had previously converted to edge rails under svn. Originally, vendor/rails was set up with svn:externals so that an svn update at the project''s root would pull the latest trunk along with all the other updates. Since Rails has moved to GiT and depreciated svn I decided to remove the svn:externals reference for vendor/rails and reinstall trunk using

ActiveRecord boolean false returning Nil
Hi All, I have a column type of boolean, and when the value in that column is set to ''false'' (eg. 0 for MySQL), it returns nil. I have tested this in the console, and it doesn''t exhibit this behavior there, only when running on Mongrel. I tried wrapping the accessor call to intercept a nil and set it to false for that attribute, but it doesn''t seem to be

before_filter: nil vs. true vs. false
Folks, My understanding of how filters work is that I should return true if everything is ok and false if not. How does the filter below work then (from the Rails Recipies book)? It would return nil if there''s a user in the session. Does nil count as true? before_filter :check_authentication def check_authentication unless session[:user] session[:intended_action] =

Updating objects in arrays
Perhaps this is a Rails issue. However, I need to first determine whether I simply am missing something about updating members of an array. I have an array of 10 ActiveRecord objects. I wish to iterate over the array and update an attribute. When I do this the underlying table row changes but the object in the array frequently does not. For example: count = 0 current_entries.each do

Shutdown KVM guest not working
I am in the middle of a rather confusing situation. At the moment I am unable to shutdown a KVM guest machine. Nor am I presently able to open a virt-manager session on the host.

Help with routing question.
CentOS-6.6 We have a host that has multiple IPv4 addresses aliased to eth0. The primary address is 216.185.71.x and the alias is 192.168.6.x. This host connects to devices on both netblocks without problems. Only default routing is used and it looks like this: #ip route 192.168.6.0/24 dev eth0 proto kernel scope link src 192.168.6.x 216.185.71.0/24 dev eth0 proto kernel scope link src
