simple output string
Hi!
I am new to Rails and wanted to know how I can print an easy
string-line.
I wanted to generate a dynamic title for my blog articles made with
"typo":
The first part of the html-title stays the same:
<title>softrockcookie</title>
if it is not the mainpage ("softrockcookie") it shall add the
page_title, so:
<title>softrockcookie <%= page_title

user authentification (not implemente yet), and then allow the user to
manage the Dicts objects. I have a

variables in layouts
I have a layout that provides the basic outline of each page in my app.
It has a title, footer and a navigation bar.
In the title I want to put the name of the current user that is logged

Is there a way I can create a sub-layout with ERB?
I have 2 pages that have almost the same content except for stuff in
the middle. I''d basically like to have a sub-layout that wraps the
content that is different - exactly the way a normal layout file
would.
