I understand your skeptism, but eventually looping through the database records *is* the right way: Froglet.find(:all).each do |froglet| # ... end Looping through the fixtures only is not possible. Even though it was, it would be a bad idea since some of the records might have changed, new records might have been added and so on. You should always be sure to use the latest state of the database. :) -- Best regards, David Knorr http://twitter.com/perplect --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Well, you do use "simple text files", just like in PHP. The difference between PHP and Rails, though, is that the only thing you need to do in PHP is to download a package like xampp (e.g.) and just put your files in the right directory. In Rails, there is a predefined directory structure, so you'll need to generate Rails projects *in the shell*. And you have to actively start the server *in the shell* to view your application in the browser. Also when you generate models and controllers you go to *the shell* and type the respective commands. As you can see, Rails uses the shell to stop you from repeating yourself and thereby it speeds up your development process. The reason why no one has explained this to you, could be because most Rails developers works in operating systems like Ubuntu (Linux) or Mac OS where the shell/terminal/command line is a completely natural place to be, in contrast to on Windows systems where most things are done via graphical interfaces. I hope you understand, and I also hope you'll come to appreciate the power of the shell. -- Best regards, David Knorr http://twitter.com/perplect --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You can easily make a back button like this: <%= button_to "Back", :back %> button_to will pass the second argument (:back) on to url_for, and as you can see in the documentation (http://api.rubyonrails.org/classes/ ActionView/Helpers/UrlHelper.html#M001564), :back will be translated to request.env["HTTP_REFERER"] or javascript:history.back() if referer is blank.

You are trying to call an undefined method 'feed_url' on an Array. To make this work you should call the method on each of the items in the Array individually. Like this: @feeds = [] @urls.each do |url| @feeds << SimpleRSS.parse open(url.feed_url) end You need to know, that whenever you're asking ActiveRecord for multiple records in the database, they will always come back as an Array with each item representing a record or model. But when you're asking for just a single record (Model.find(:first) or Model.find (:last)) you simply get the record/model back. -- Best regards, David Knorr http://twitter.com/rubyguy --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
