Rails

Hi there,

I’m Vignesh developer @ Rails application. I was now getting an issue
while
I’m migrating my existing application with rails ‘3.2.13’ into rails
‘4.1.beta1’ .

This was my issue while i m signing in into my application

no _dump_data is defined for class Mysql2::Result

So if anyone could have some idea about the issue. Please share your
ideas
and it may be helpful for fixing it. :slight_smile:

Thanks,

Vignesh.

The Mysql2::Result class is a thin wrapper over the underlying C
interface

  • in particular, it can do things like on-demand streaming of rows from
    the
    database. It’s not Marshal-able because most of the state doesn’t live
    in
    Ruby code.

As noted in the issue on the Mysql2 gem
(Marshal dump fails for Mysql2::Result · Issue #275 · brianmario/mysql2 · GitHub), the workaround is to
convert the Mysql2::Result instance to a hash or an array (fetching all
the
desired rows) before caching it.
