Thanks for your hint, I have tried the problem and please check this
whether it is correct or not
Models requires:
class Article < ActiveRecord::Base
has_many :related_articles, :dependent => :destroy
has_many :info, :dependent => :destroy
has_many :comments, :dependent => :destroy
end
class RelatedArticle < ActiveRecord::Base
belongs_to :article
end
class Info < ActiveRecord::Base
belongs_to :article
end
class Comment < ActiveRecord::Base
belongs_to :article
end
Each article can be related to many articles (or none). -- YES
Cleaning up the code:
class ArticleController < ApplicationController
def show
@article = Article.find(params[:id])
if current_user.roles.map {|r| r.to_s}.include?('admin')
@info = @article.info.first
else
@info = nil
end
if params[:show_comments] && params[:show_comments] != ''
@comments = @article.comments.first
end
if !(params[:hide_related] && params[:hide_related] != '')
@related_articles = @article.related_articles
end
end
end
