Hi Ryan,
Is it still the norm to change environment.rb or should we be doing this in the initializers?
Cheers,
Aditya
Minor thing: you can do RAILS_ENV=test instead of RAILS_ENV='test'.
@Aditya, anything that uses "config" I like to keep in the environment.rb. Anything that doesn't (where you can specify it after the config) then move that into an initializer.
@Henrik, yeah, my quote finger was a little twitchy last night it seems. ;)
Another great rails cast!
Could you do some on ActionMailer?
Ryan, as always great videos. Loved the 2.1 updates. I've recently been using config.gem and I think I found a problem using it with BlueCloth: http://railsforum.com/viewtopic.php?id=18850
Any idea whats going on here?
Thanks for another great screencast. I just came across a gem's instructions to use:
:version => '~> 2.3.2'
What does ~> mean?
Nevermind, there was an explanation:
gem 'mislav-will_paginate', '~>2.1'
# this will load any 2.x version
#(greater or equal to 2.1),
# but not 3.x
I am currently using mislav-will_paginate gem.
When I give it in environment.rb, it shows me 'mislav-will_paginate' file not found. I have given the proper version and source. Still it shows me the same error. How can I get rid of this error?
I'd love to see how to make a gem plugin, similar to how you made a normal plugin in episode 33!
@madan, I had the same problem with a number of gems. It happens when the library module you're going to use is named differently from the gem. For example if you say
config.gem 'chardet'
=> rake can install the gem, but not unpack it, and rails gives the error
no such file to load -- chardet
and script/about gives the error
These gems that this application depends on are missing:
- chardet
To avoid this, you have to specify the name of the module:
config.gem 'chardet', :lib=>'UniversalDetector'
config.gem "mislav-will_paginate", :lib => "will_paginate"

@jhxc
thanks for the explanation!
@ryan
you made me smile ;-)
Getting wrong number of arguments error, environment.rb:13
The rake gems:install command is very useful.
Great screencast again - thank you.
excellent stuff, helped out my cms setup.
love the capistrano stuff, will simplify things greatly ;-)
Hi all..
How do we know where is the :lib option for gem is located? I've tried to catch it from gem documentation, i've gotten for some gems and the others aren't provide it..
I have downloaded 2.1 version and it worked very vell. thanks a lot
If anyone is having trouble uninstalling a gem from your home directory ~/.gem please check out this link:
http://blog.floehopper.org/articles/2009/02/16/uninstalling-gems-from-gem-directory
This was frustrating for me and I had to do this to fix it:
gem uninstall <gem-name> --install-dir=~/.gem/ruby/1.8/
and then run "sudo rake gems:install"
Anyone know if there is a way to send build options to 'rake gems:build'? I need to set the '--with-mysql-dir=/usr/local/mysql' for the mysql gem.

Ryan,
Do you know if there is a way to override the location of where the gems:unpack will go rather than having them go under vendor/gems? This is a case where multiple rails applications use the same version of a gem and we want to only store one copy of it in source control. Also is there a way to tell rake to look in a directory for gems and when you run gems:unpack so they are grabbed from the shared directory? Thanks in advance.
Thanks for good screencast. I just came across a gem's instructions to use:

It's great to see an article like this. www.mbtselling.com www.jerseystown.com www.dunkjordan.com www.airmaxsupplier.com www.ghdbeautyhair.com
Through my 27 years of infinite wisdom (my parents always said I was a smart-ass), I've learned a few things. Women, yea I consider myself an expert in the female area if you know what I mean (wink) - and the most important thing I've learned is to stay away from a woman on her PMS days. In fact, I've put together a few acronyms (abbreviations) based on my experience with the syndrome.
