Passing a parameter via URL

[Pixelateur]

Hi there,

I want to pass a parameter with a method invoked from an .rthml file. How can I do that?

The method is called list_by(category) and is located in an ordinary .rhtml page. The category parameter changes depending on the context. But it can never be invoked because URLs can't display brackets. Do you get what I mean? Can anybody help?

Do you mean something like:

url_for(:param => list_by(category)

I'm not sure what you mean.
