So i am trying to make a way to list the previous articles in a list format not by date or month but simply by order published, also be able to break that up into multiple pages (page one is 12 articles page 2 is 12 and so on) in a dynamic fashion. I have tried to modify the \ tag to accept a passed variable that tells it what the current offset is but that has been to no avail i dont care if its by passing a variable or by using tags or making a new behavior i just want a simple page that lists all my articles in order dynamically allocating how many articles can be viewed per page ---

The easiest way I’ve found to do what you’re saying is to create virtual pages. For one page type I constructed for kckcc.edu, I mimiced the find\_page\_by\_url functionality of the ArchivePage, then returned a virtual subpage that was capable of handling the request. I used this to handle a custom model, but the same could be done for pages. Here’s the URL: [http://www.kckcc.edu/academics/course-descriptions](http://www.kckcc.edu/academics/course-descriptions) Each of the apparent child pages of that page are actually a single virtual page that uses the passed URL to determine which collection of models to display.

I am going to my other computer in a few hours and i will try to use this, if you have a version of this that definitely works for trunk id love you even more im pretty noob overall when it comes to ruby but im starting to get the hang of it. Thanks everyone for trying to help me out with this i have to say i will stick by radiant and do what i can to help indefinitely!
