I’m running the following code in my show() method:
@articles = Article.find(:all, :conditions => ["issue_id = ?",
@issue.id], :order => ‘
if (params[:article_id]) @article_id = params[:article_id].to_i c = 0 total = @articles.count while (c < total) if @article_id == @articles[c].id if c == 0 @article_prev = @articles.last.id else @article_prev = @articles[(c-1)].id end if ((c+1) == total) @article_next = @articles.first.id else @article_next = @articles[(c+1)].id end end end else @article_id = 0 @article_main = @articles.first.id @article_prev = @articles.last.id @article_next = @articles.id end
Now to be honest this code is already a bit odd for me but I have no
idea how else to approach this in Ruby on Rails. So I’ve attempted to do
it PHP-style. But I’m being told that I can’t do @articles.count
Why? I have a user model and a user has a one to many relationship with
articles so I know that: @user.articles.count works. Hence I’m guessing
there’s something big I’m missing here.
So, how am I going to do this? How do I easily cycle through my list of
articles and get the previous and next ones?
Any help greatly appreciated. I’ve been going back and forth over my
books and forums but I can’t seem to formulate the question to be able
to ask it.
