I have a Post model. Posts have many Comments. I want to generate a <ul> element for post.comments using content_tag_for.
Ideally, it'd produce
<ul id="comments_post_7" class="comments">
...
</ul>
where 7 is the ID of the Post.
The closest I can get uses
<% content-tag-for :ul post, :comments do %>
which produces
<ul id="comments_post_7" class="post">
...
</ul>
which is pretty close, except for the class="post". Using :class => :comments in the content_tag_for yields class="post comments", but I just want class="comments".
It seems logical that I'd be able to use something like
<% content_tag_for :ul post.comments do %>
but, sadly, that yields
<ul id="array_2181653100" class="array">
...
</ul>
I've searched far and wide. I feel like I'
m missing some elegant way to do this. Am I? Because, seriously, <ul id="comments_post_<%= post.id %>" class="comments"> is painful.
