I just installed Rails 2.3.2 and tried to upgrade my test app from  
2.1.2. After installing Rails 2.3.2, I simply changed the gem version  
in my environment.rb file in config directory as shown below:

# Specifies gem version of Rails to use when vendor/rails is not present

RAILS\_GEM\_VERSION = ‘2.3.2’ unless defined? RAILS\_GEM\_VERSION

The server refuses to start and I get the following stacktrace:

=\> Rails 2.3.2 application starting on [http://0.0.0.0:3000](http://0.0.0.0:3000)

Change it back to 2.1.2 and I am fine. Is there something that is  
missing? I do a rails -v and it shows that 2.3.2 is installed as shown  
below:

bruparel@bcr-d810:~$ rails -v  
Rails 2.3.2  
bruparel@bcr-d810:~$

Thanks for your time.

Hi, did you update your configs?

rake rails:update

No. I had not done that, but after reading your reply I did, but I get  
the same error 🙂 as can be seen below:

bruparel@bcr-d810:~/exp/pizzeria-3$ cd config/  
bruparel@bcr-d810:~/exp/pizzeria-3/config$ vi environment.rb

Note that I edited the environment.rb to set Rails Gems to 2.3.2, but it  
does not work.

Hello Conrad,  
I am making good progress towards resolving this, but am not there  
entirely. Following is my abbreviated environment.rb file. Note that I  
have commented out the RAILS\_GEM\_VERSION line so that the latest rails  
2.3.2 is loaded.

# Specifies gem version of Rails to use when vendor/rails is not present

#RAILS\_GEM\_VERSION = ‘2.1.2’ unless defined? RAILS\_GEM\_VERSION

# Bootstrap the Rails environment, frameworks, and default configuration

require File.join(File.dirname( **FILE** ), ‘boot’)

Rails::Initializer.run do |config|

# Add additional load paths for your own custom dirs

config.load\_paths += %W( #{RAILS\_ROOT}/app/form\_builders )

config.time\_zone = ‘UTC’

config.action\_controller.session = {  
:session\_key =\> ‘\_pizzeria\_session’,  
:secret =\>  
‘1cac89a5ef8e67d30b297648243baee84a52d16dbbf11690733a73c825da43c327a6552f9498d0fe2ecf29cbc09ebf6115102fe3d26f969909f005dc1da39e09’  
}

require “#{RAILS\_ROOT}/lib/active\_record\_extensions.rb”

end

if I comment out the last require  
“#{RAILS\_ROOT}/lib/active\_record\_extensions.rb”

statement as shown below:

# require “#{RAILS\_ROOT}/lib/active\_record\_extensions.rb”

and restart the server then it boots and everything works fine except  
where I need the functionality contained in  
lib/active\_record\_extensions.rb file which is as follows:

module ActiveRecord

class Base  
def self.search(search, current\_page, search\_field)  
if search.blank?  
paginate(:all, :page =\> current\_page || 1, :per\_page =\> 5)  
else  
paginate(:all, :conditions =\> ["#{search\_field} LIKE ?",  
“%#{search}%”], :order =\> ‘name’,  
:page =\> current\_page || 1, :per\_page =\> 5)  
end  
end  
end

end

Why does Rails 2.3.2 have a problem with it when 2.1.2 does not? The  
error messages are very misleading and point to some problem with  
database when there is none?

Figured it out:

Rails 2.3 has a problem with requiring any files within the initializer  
block as shown below.

Rails::Initializer.run do |config|

require “#{RAILS\_ROOT}/lib/active\_record\_extensions.rb”

end

Instead, it wants you to put your require statement outside the block as  
shown below:

Rails::Initializer.run do |config|

…

end  
require “#{RAILS\_ROOT}/lib/active\_record\_extensions.rb”

This works. Why is it so? I do not know. If someone can explain this,  
I would appreciate it.

Thanks.

Bharat

ActiveRecord is not loaded at this point. The right place for this  
sort of stuff is in an initializer (see

for ways where putting it at the bottom of environment.rb can go  
wrong).

Thanks Fred. Here is what I did after reading the link that you posted:

I created the config/initializers/load\_lib\_dir.rb with the following  
line of code:

Dir.glob( “#{ RAILS\_ROOT }/lib/\*.rb” ).each { |f| require f } \<-- thanks  
Greg.

I guess, I have some homework to do on the initializers.

Regards,

Bharat

Please use  
rake rails:update

After you update your rails version, you should check your app, the  
config file and the plugins.  
Most time ,the errors are happening in the config file(config/  
environments/…) and the plugins.
