That's because it doesn't matter.  :-)

What is the output of `sudo gem install rails` ?

What is the output of `gem list --local` ?

What is the output of `gem env` ?

No there are no underscores. only alphabets and numbers.


So, try using /[a-zA-Z0-9]/ as your constraint. I can't remember a shortcut for alphanumeric, if there is one.

Was it ok when you created the database (rake db:create) or if you did
not create it like that are you able to run migrations ok?  (And are
you still able to run migrations ok).

Re: Overriding number_to_human (Rails 3.0.5)



On Wed, Oct 26, 2011 at 10:23 PM, cipher_neo <l33z3r <at> gmail.com> wrote:
I encountered a problem today, in that the number_to_human helper has a defect where it spits out an error when passed any number bigger than 0 and less than 1. 

eg number_to_human(0.2) gives "nil can't be coerced into fixnum"

So, I found this patch:


Now to apply it, I had to create a file: lib/number_helper_overrides and put the override code in there:

module ActionView
  module Helpers 
    module NumberHelper
      def number_to_human(number, options = {})
        #the code in here bla bla
      end
    end
  end
end
 
then in environment.rb I put:

require "number_helper_overrides"

Is this the proper way to override in rails 3?

If so, then should I really need to put the "require" statement into the environment.rb file? 
I already have the autoload path set to load file from the lib directory?


Have you tried putting it in config/initializers/?  You won't need the require statement if you put it there.

 
thanks, 

Lee

echo command in rails

Hi,

    I am following the instructions given in the link
"http://mutoumahendra.blogspot.com/2010/07/tinymceplugins-spellchecker-on-rails.html"
for doing spell check.

    The problem I am facing here is, I am not able to run
`echo "#{spell_check_text}" | aspell -a -l #{lang}` command while
executing command. When I execute the method the above command is
returning blank.

My question is How to run echo "statement" in rails.

In command prompt I am able to run the echo using exec 'echo blah blah'.

Cheers,
Rana.
