If you're new to the world of web development, it might help to have a bit
of context on what Camping's models actually are. ActiveRecord is an
abstraction of a database that's primarily developed for use in the Ruby on
Rails framework, which you could argue Camping is to some extent a
rebellion against.
In early web apps, people would manually embed SQL query strings in scripts
and templates written for PHP, Perl, Python, etc. This approach has several
problems, possibly most importantly: it's difficult to scale the
functionality of a web app or make it more interactive, and it's vulnerable
to attacks like SQL injection, where malicious input can have an
undesirable effect on server-side behaviour.
Most popular web frameworks use something called an ORM, which is what
ActiveRecord is - the data in the database is represented via classes and
native objects in the code. Camping is somewhat uncommon as a lightweight,
beginner-friendly framework that has a built-in ORM (though there's nothing
forcing you from using its neat rendering and routing features without
bothering with the Models, or from implementing your own Models atop
files or a noSQL database.

Hi Cj
I don't think anyone answered your question, so here's a quick reply.
Since you said I'm not sure I understand what models do I presume you're
a beginner, so this states what may already be obvious! I'm still a noob at
heart too.
You don't really need a models module to do what your little app does -
there's not enough data to warrant it. Here's the Camping intro to models:
http://camping.io/Book/-Getting-Started#Modeling-the-world
Basically, you'd use models when constructing an app that needs a database
- take a look at the models module in the Camping blog example (
https://github.com/camping/camping/blob/master/examples/blog.rb)
By default, models use ActiveRecord (with a Ruby-friendly syntax) to
create and manage the database (SQLite is the Camping default).

Hello,
I'm new to ruby and camping. I'm learning ralis along with camping. I like
camping because the MVC is all on one page.
So, I'm wondering if you can help.
Here's my code. https://gist.github.com/3562873
I'm writing a little app that displays a random quote when you refresh the
page.
On line 30 and 31 I have an array and show the index page and sample the
array.
So, guide me on how to put this in the model module. But I'm not sure I
understand what models do. Told you I'm a noob!
Thanks in advance for your help.
Cj.
