Rails - Oct 2011 - append the hash error

Hi,

  i want to capture a obj.errors value into a new hash for example

a = Hash.new
obj.errors = { :a => "can''t be blank" , :b
=>"should be alphanumeric" ,:c =>
"Not in the list"}
a   << {0 , obj.errors}
end

 it says error like that

undefined method `<<'' for {}:Hash



pls what i miss in this syntax

 thanks in advance

What it''s trying to tell you is that the line I quoted above is
syntactically incorrect -- that Class Hash does not have a << method.
See http://www.ruby-doc.org/core/classes/Hash.html for more info on
hashes.

But to take this a step further, are you sure you want to store it in
a hash, not an array?  Arrays do have a << method, and it doesn''t
look
to me like you''re storing obj.errors under a really meaningful key.

If you really do want to store obj.errors as the value for key 0, that
would be done as:

  a[0] = obj.errors

or if you want to store the zero as a string not a number,

  a[''0''] = obj.errors
