I was trying to build a blog webpage. I followed the steps of cookbook2. Now I want to add some new functions to my blog system.That is, I want to show all blogs that belongs to one category when I click the category's name on category/list.rhtml.Also, I want to add a new link to view all the categories from blog/list.rhtml. But I have trouble with how to do it. I want to call the category's list action from blog/list.rhtml but I don't know how to do it.
I hope I have explained my question clearly.
