I am trying to add comments to my blog.
comments_controller.rb:
def create
@blog = Blog.find(params[:blog_id])
@comment = @blog.comments.create(params[:comment])
redirect_to blog_path(@blog)
end
In my blog’s index view:
<% form_for([ @blog, @comment ]) do |f| %>
…
<% end %>
blog.rb:
has_many :comments
comment.rb:
belongs_to :blog
routes.rb:
map.resources :blogs, :has_many => :comments
The error I get is:
undefined method ‘nil_class_path’
and it points to the form_for line
I can add comments from the console, but if I attempt to view them by
adding “@comments = Blog.comments.all” to my blog_controller’s index
action, then "<% @comments.each do |comment| %> " into the
corresponding view, I get an “undefined method ‘comments’” error
Any assistance would be awesome. And I am only using rails 2 because
my host does not support rails 3. I do not have any trouble getting
the above to work in rails 3, but i don’t know what I am doing wrong
now.
Thanks.
