I’ve
run into the issue before where a Rails app doesn’t run on a server due
to a gem not being installed. Adding them to your application seems
like a perfect solution and deals with other computers possibly having
various versions of gems installed.
My
expectation was that when I create a hash it’s going to act like a
queue and be sorted in the order in which I inserted things. As I found
out today, that is definitely not the case.
There is a very easy way that Rails offers to give a hash this behavior and it’s the OrderedHash function found in the ActiveSupport libraries.
my_hash = ActiveSupport::OrderedHash.new
After that initialization, your hash will be maintained in the order you insert things. Something to watch out for.
I recently upgraded a few projects to Rails v.1.2 and had a couple of issues arise.
Disappearing objects when dropped using drag and drop in Safari
For one project I use the drag and drop re-ordering provided by the Scriptaculous
library. Not sure what did it, possibly even a Safari update, but only
in Safari, once you let go of a dragged object, that object would
disappear. It would come back when you refreshed the page and would
have successfully triggered its intended action.
I did
update my javascript files upon upgrading to v.1.2.1, but had not upon
the upgrade to v1.2.2 since I wasn’t aware of any changes. I think the
release of Scriptaculous on its actual site is newer (v1.7 right now)
than that included in Rails so I updated my scripts and that solved the
problem.
Model attributes not in the database were inaccessible
I
wasn’t able to figure this one out, but was able to get around it. I
have a model which has some methods to send/receive messages to a
device. I had a
attr_accessor :last_response
which is an attribute
that’s not in the database. It was simple a place to temporarily store
the full message of the last response for use later on in the code.
After the upgrade to v1.2.1 things were fine. However after updating to
v.1.2.2, I started getting “Method not defined” errors. It seems like
other people have hit this one, too.
My solution was simply to remove the property and change it to @last_response which worked for my limited use of it.
I’m
still scratching my head though, since similar attributes work fine in
other classes. The problem class, however, is unique in that instead of
having ActiveRecord:Base as its parent, the actual parent is a generic
class whose parent is ActiveRecord:Base.
I
couldn’t wait so I got all the bits and pieces for a new gaming PC and
they all arrived the end of last week. It actually went together
quicker than I thought it would, so I was left trying to decide if I
wanted XP or Vista on it. Considering I have an MSDN subscription with Microsoft and have licenses for Vista already, I decided to download the latest ISO images and install the Home Premium version.
It seems fine now, but here are some of the issues I’ve run into:
Vista would not install on an unformatted disk
I
kept getting an exception error when the installer was trying to load.
Some research indicated that a lot of people have run into the same
thing. In some cases it was a bad DVD or CD
burn, but in others, the solution was to run through the Windows XP
install far enough to format the hard drive. So after doing a base
install of XP Home, I booted up with the Vista DVD I created and the installation process went through.
Video Drivers
nVidia’s
drivers for Vista are still in beta, so I had to download those to get
the full benefits of my new graphics card. It’s unknown whether or not
the drivers will be out of beta when Vista hits the stores. I have seen
what I’ll call weird video events when the screen switches modes for
games and sometimes when launching apps, so it’s not quite finished
baking yet.
I Allow…
Uggghhh. I’m already tired of
getting asked to Deny/Allow any little thing that happens. I can
understand it from a security standpoint, but having experienced
similar permission prompts on Mac and Linux, Vista’s prompts seem
excessive.
World of Warcraft Updates
I’ve been able
to install a few games, Doom 3, Half-Life 2 Eps. 1 and World of
Warcraft. All are working great. However, I did run into one issue
patching World of Warcraft, but was able to quickly find a solution on
their forums. One of the patches (not all of them) would bomb out at
the end and not get applied. It made a change to the Start Menu links
for the game which Vista did not like and since Vista didn’t prompt me
to allow it, the patch would not install. The solution was to manually
apply the patch by right clicking the patch executable and selecting
“Run as administrator”.
Otherwise
Everything else
seems to be fine but I’m not doing anything but playing games so far.
This won’t be a development machine, but I can at least use it for IE7
testing since I still want to keep IE6 on my work notebook as long as
possible for easier testing.
