try to fix the thing i suggested in red and add a parent_id field to the
comments table,
then make a self referencial associaction or use the acts_as_tree gem, the
thing is along with
the polimorphic fields a comment should be able to belong to another
comment, when you try to make a comment
belong to another comment with the same association you are using for when
it belongs to article or anything else
the migration to that polymorphic parent is lost, why ? because you are
using this function
def find_commentable
params.each do |name, value|
if name =~ /(.+)_id$/
return $1.classify.constantize.find(value)
end
end
nilend
with it you are trying to find what comments owns the new comment that was
added as a chils.
but this
~ /(.+)_id$/
pulls from the params hash, the params hash passes the model that has
comments nested not the
comment want to attach your new comment to.
also you are calling new on something that will call new again, that is when
you check with new to build the child
is tries to see who the parent is but you mistankenly pass the same object.
if need more details on how to fix all this, i can try to help, but as you
notice my english is far from perfect.
here is how the acts_as_tree gem works
