Hi everybody! Since there`s not much documentation for awasome_nested_set , acts_as_commentable etc , i`m trying to build the  
nested comments in easy way :

event.rb  
…  
has\_many :comments  
…

comment.rb  
…  
belongs\_to :event  
…

the following method saves the comment:

def post\_comment  
@comment = Comment.new(  
“event\_id” =\> flash[:event\_id], # yes, i store it in flash  
“created\_at” =\> Time.now,  
“comment” =\> params[:comment][‘comment’],  
“commenter” =\> current\_user.login  
)  
if @comment.save  
…

what i want to do is add “parent\_id” column to comments table, add  
“parent\_id =\>…” to post\_comment. Then display a ‘Reply’ link under  
each comment. The problem is i have no idea how to pass parent\_id while  
replying comment

the comments are displayed by the partial :

- \<%=comment.commenter.capitalize%\> says:   
\<%= h comment.comment %\> 
 Posted \<%= comment.created\_at.strftime("%B %d, %Y at %I:%M %p") %\>  
 \<%= link\_to 'Reply', "something"%\> 

I added some comments with parent\_id manually to comments table, now i  
need the way to change my partial to display all the child comment for  
each parent comment.

i would really appreciate any suggestions/ideas . Thanks!

Bad idea. Go with awesome\_nested\_set . I don’t know why people keep  
saying it’s poorly documented – although the Github pages don’t say  
much, the rdoc is very clear.

What are you asking here? About dealing with parent\_id? You can pass  
that in the URL or similar. I’ll try to check how I did this last time  
I had to…

please, guys, can somebody just throw me some theory/suggestions.

I have the comment models  
event.rb which has\_many :comments

and comment.rb which belongs\_to :event and acts\_as\_nested\_set (awasome  
one)

how do i manage the comments?
