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

nice video :) thanks!

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

Justs another great screencast. Very helpful - Thanks

Thanks for making this feature clear. The podcast really helps.

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..

very interesting video

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"

thank you so much
it is great....

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.
