help with final project

Hi,

I am kinda new to ruby but i know how to do the basic stuff but this has me really stumped. 

I want to create a page were a user can create a shipment with a customizable supply chain. For example: a user makes a new shipment so it starts at the origin and then it goes to point A for packaging then to point B then to point A again then to point C then to point D then to B then to the destination. 

Every shipment starts with an origin and ends with a destination, and every point should have a page. points can repeat and the user creates the points.

                                         

	New Supply chain page
	origin
Create new shipment page	point A
previously created  supply chains list	point B
create new supply chain	point A
	point  C
	point D
	point B
	destination

Origin	point  A	Destination
title	title	title
text	text	text
upload attachment	upload attachment	upload attachment

Does this make sense? How can I go about doing this? what is this called? Is there a tutorial I can watch that is similar? 

any help will be appreciated. 

Thanks

My approach in this situation would be to first consider how to store the data, then later work out how to display and enter it.  So you need to decide on the models (possibly User,  Shipment, Location), the relationships between them (has_many, belongs_to etc), and the attributes for each object.  Think about that first and come back to discuss your ideas if you are not sure.
