Question

Problems while upgrading the rails version.

Answer 1

A:

You can make sure whether you have upgraded properly or not by going to script/console and whether it prints out

Loading development environment (Rails 2.3.4)

or not as you enter the console, that might give you some hints.

Thanks for your response nas! I have upgraded the rails version , but when i run the rails -v command it shows 1.2.3. Is there anything to change?. Could u please help with the steps to be followed to upgrade the rails version from 1.2.3 to 2.3.4?

Looks like its not installed properly or at all if rails -v shows 1.2.3. In that case, can you just run again 'sudo gem install rails' from the command line. And before doing that do "gem list rails" and see the versions installed.

I un-installed everything and again I re-installed the rails application. Now it went through nicely.But now having a problem with cache_template_extensions error even after i removed from config/environments/development.rb.

sam 2010-02-12 11:03:03

Can you do a grep/search for cache_template_extensions in your config directory or the whole app and just delete it if you find it anywhere

nas 2010-02-12 11:58:17

Hey nas. I have also come up with the master search of my application for cache_template_extensions error,but nothing was found. Just ,I was blank with this. Is there any other reason for this error to occur?

sam 2010-02-15 12:09:10

I cannot think of any but can you run a gem list command on your system and paste the output here?

Answer 2

+1 A:

Did you change your RAILS_GEM_VERSION in the config/environment.rb file? It may still be looking for the 1.2.3 gem, as opposed to the 2.3.4 gem.

Thank you for your quick response josh. But i have changed the rails version to 2.3.4 in environment.rb file and also i have freeze the gems in the current application with 2.3.4 version.One thing which i cant understand is .... when i run the rails -v command in console it shows the rails version as 1.2.3. . Could you please help me with this? Is there any other file where we should change the rails version. But i have upgraded the rails version.Thanks in-advancesam

If you run the following command, `which gem`, you can see where the gem binary file. If 1.2.3 is using on executable, and you've installed the 2.3.4 gem with another executable (and its not in your path), you might run into problems. Install the 2.3.4 gem with the same executable as with 1.2.3.

Answer 3

A:

Check if you have a copy of rails in the vendor directory. Also, what does script/about show?

Roger Ertesvag 2010-02-11 11:01:00

hello Mr.Ertesvag. I have checked that whether i have a copy of rails in the vendor directory.I dont have one. when i run the ruby script/about command i am getting error as rails requires ruby gems >=1.3.2. So i run gem update --system command.when i run this command it shows nothing to update.but when i run the ruby script/about command am getting the same error.
