Я использую Act_as_commentable_with_threading gem.
Мой _new.html.erb
<div class="adding_comment"> </div>
<%=form_for [commentable, Comment.new], :remote => false do |f|%>
<%=f.hidden_field :commentable_id, :value=> @post.id %><br/>
<%=f.label :title%> :<br/>
<%=f.text_field :title%><br/>
<%=f.label :subject%> :<br/>
<%=f.text_field :subject%><br/>
<%=f.label :body%><br/>
<%=f.text_area :body, :style=>"width:320;height:80px"%><br/><br/>
<%=f.submit "Add comment"%>
<%end%>
Контроллер комментариев:
class CommentsController < ApplicationController
def create
@post = Post.find(params[:comment][:commentable_id])
@user_who_commented = current_user
@comment = Comment.build_from(@post, @user_who_commented.id, "Comment!" )
end
end
В моей модели поста ядобавлено:
acts_as_commentable
В моей записи show.html.erb:
<%= render :partial => "comments/new", :locals => { :commentable => @post }%><br/>
<h1>Comments</h1>
<div id="comments">
<%=render :partial => 'comments/index',:locals => {:commentable=> @post, :comments => @comments}%>
</div>
Но после нажатия кнопки «Отправить» я получаю сообщение об ошибке:
Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id
Request:
{"utf8"=>"✓",
"authenticity_token"=>"2GvCfaCB/qAxdh+1jJvcZ76jL9fdxP+h5qEIOClmNHk=",

"subject"=>"et",
"body"=>"ewt"},
"commit"=>"Add comment",
"post_id"=>"google-search-and-search-engine-spam"}
Пожалуйста, помогите мне.Благодаря.
