Hey guys, I have a weird problem and I think you are able to solve it easy.
I have two models - "Posts" and "Comments". A post :has_many comments and a comment :belongs_to a post. I followed the guide on http://guides.rubyonrails.org/getting_started.html#adding-a-second-model so I added the following code to my Post-view: = form_for([@post, @post.comments.build]) do |f| = f.label :author = f.text_field :author = f.label :content = f.text_area :content = f.submit I added some validation to my Comments-model, so it looks like: class Comment < ActiveRecord::Base belongs_to :post validates_presence_of :author end My comments-controller looks like: class CommentsController < ApplicationController def create @post = Post.find(params[:post_id]) @comment = @post.comments.create(params[:comment]) redirect_to @post end end Creating new comments works fine, and if I leave "author" empty the comment will not be saved. That's good. But now I wanna show the validation-errors. Normally I would do that with adding something like - if @comment.errors.any? - @comment.errors.full_messages.each do |error| = error to the formular in the post-view, but of course @comment is undefine in that view. How can I show the errors there? Regards, Dennis -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
