# The models

Let's review what we want this app to do:

 * Track multiple projects
 * Each having a collection of stories
 * Stories are just a brief chunk of text
 * A story can be assigned a current status and a set of outstanding tasks
 * Tasks can be assigned to users
 * Users can get an easy heads up of the tasks they are assigned to

Sounds to me like we just sketched a first-cut of our models. We'll start with:

 * `Project` (with a name)
	has many stories
 * `Story` (with a title, description and status)
	belongs to a project
	has many tasks
 * `Task` (with a description)
	belongs to a story
	has many users (through task-assignments)
 * `User` (we'll stick with the standard fields provided by Hobo)
	has many tasks (through task-assignments)

Hopefully the connection between the goal and those models is clear. If not, you'll probably find it gets easier once you've done it a few times. Before long you'll be throwing models into your app without even stopping to write the names down. Of course -- chances are you've got something wrong, made a bad decision. So? Just throw them away and create some new ones when the time comes. We're sketching here!

Here's how we create these with a Hobo generator:

	$ ./script/generate hobo_model_resource project name:string
	$ ./script/generate hobo_model_resource story   title:string body:text status:string
	$ ./script/generate hobo_model_resource task    description:string

Task assignments are just a back-end model. They don't need a controller, so:

	$ ./script/generate hobo_model task_assignment
