Hi,

i’m trying to use the acts as commentable Plugin, bit it seems not to  
work:

My Commentable Model is the Task Class.

if i try to get the Comments of a Task Object , e.g.

task.find(:first)  
task.comments

it occurs this error:

ActiveRecord::StatementInvalid: Mysql::Error: Unknown column  
‘comments.task\_id’ in ‘where clause’: SELECT \* FROM `comments` WHERE  
((`comments`.`task_id` = 4)) ORDER BY created\_at ASC

What do i made wrong?
