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
