<p>I am new to RESTful stuff.  But, I want to use it in my rails app.  When I add this to my routes.rb <code>map.resources :notes</code> I get routes to these methods created:</p>

<ul>
<li>index</li>
<li>create</li>
<li>new</li>
<li>edit</li>
<li>show</li>
<li>update</li>
<li>destroy</li>
</ul>

<p>What I am wondering is what is the difference between edit/update and create/new?  Is there any standard definitions of how these method pairs vary and what each one does?</p>

When you use the scaffold generator in Rails 2
```
create
```
is the action called when the form from the
```
new
```
action is submitted.  Likewise,
```
update
```
is the action called when the form from the
```
edit
```
action is submitted.
As far as I know, you can blow that away and define them to do whatever you want depending on what
```
create/new/edit/update
```
means to your application.
