Ruby on Rails

Hello,

Thank you for your remarks but it doesn't seem to be the reason here:
"cards" is not in "Parameters" but it successfully accesses the
attribute when I log it.
I have run another page to display a game (already existing in the db),
I have got the same error "void value expression" when trying to access
the attribute "players" of the Object "game" (previously it worked
fine).

It appears that rails doesn't know about the "players" attribute. Where
should I check the definition ?

Thank you for your help, I'm really stuck.
