Submit redirection to incorrect URL

Hi,

I'm new to rails and I'm building a small app. I have an album model
that can have many comments. Albums belong to families, laid out in
routes.rb. I want to be able to add comments in my /albums/
show.html.erb. I currently have this in the album controller:

def post_comment
    @comment = Comment.new(params[:comment])
    respond_to do |format|
    if Comment.save
    flash[:notice] = "Comment added"
    format.html { redirect_to(@family, @album) }
  end
end
end

and in the show.html.erb

<div id="comments">
<center>
<% if @album.has_comments? %>
<% for comment in @album.comments %>
  <%= comment.user.login %> on <%= comment.created_at %>
  <%=h comment.text %>
<% end %>
<% end %>
</center>
</div>

<%= link_to_function "Add another comment" do |page|
  page.insert_html :bottom, :comments, :partial => 'comments' end %>

and the _comments.html.erb looks like:

<% form_for(:comment, :url => {:action => "post_comment"}) do |f| %>
...
<% end %>

routes.rb:

  map.resources :families do |families|
    families.resources :albums
  end

The problem is that whenever I hit submit in the Albums show view, it
re-directs me to /albums/post_comment, which doesn't work because it
can't find a family.id - I would like to remain on the /family/id/
album/id page. Is there something else I need to do here because the
Album controller is a nested resource?

Thanks,
Ryan

Still having trouble on this one - anyone have any ideas?

Here's the log entry:

"comment"=>{"text"=>"test", "album_id"=>"1", "user_id"=>"1"}}

ActiveRecord::RecordNotFound (Couldn't find Family without an ID):

So, I believe that the action in the album controller is working
correctly, since it is being processed, and all of the data is passing
through correctly in the parameters, but it is still directing me back
to /album/post_comments instead of /families/id/albums/id - any ideas?

Thanks,

in your post_comment method

def post_comment
    @comment = Comment.new(params[:comment])
    respond_to do |format|
    if Comment.save
    flash[:notice] = "Comment added"
    format.html { redirect_to(@family, @album) }
  end
end
end

change the arguments in redirect_to
@album to @comment.album
and
@family to @comment.album.family

OR

change the whole line
format.html { redirect_to(@family, @album) }
to
format.html { redirect_to(family_album_path(@comment.album.family,
@comment.album)) }

whichever is easier for you.
