Partial rendering one time too many for collection
Creating a simple blog application,
I have this partial
.comment
%p
%b
Namn:
= comment.name
%p
%b
kommentar:
= comment.content
%p
= link_to 'Destroy Comment', [comment.post, comment],
:confirm => 'Are you sure?',
:method => :delete
and its called from
= render :partial => 'comment', :collection => @post.comments
it always renders the partial one time to many?
edit:
It has this form
= form_for ([@post,@post.commen开发者_高级运维ts.build])
As depicted in the comments of your question, the @post.comments.build
is the culprit. Change it to
= form_for ([@post, @post.comments.new])
and the additional item when rendering the collection should be gone.
There is a good post about the difference of build and new here: Build vs new in Rails 3
