Hello folks,
I have models called Address and Cart and both have their needed RESTful actions in place. Now there's a third model called Despatch which assigns the Cart's contents to a chosen Address.
Ideally then, to keep DRY, I'd like to rely on my Address and Cart controllers for:
1. choosing an Address as a recipient 2. displaying the Cart and allowing the user to make any modifications to its contents
before having my Despatch controller create the despatch.
My plan is to:
1. have the Despatch controller set a session variable to indicate that a despatch is being done
2. have the Address and Cart actions check that variable and alter their displays accordingly, ie Address index will display a select as recipient link in addition to the usual CRUD links.
3. have each step in the process point to my Despatch controller's new action, with a params variable to indicate which step the user is at, ie choosing recipient (redirect_to addresses_path), modifying cart (redirect_to cart_path).
4. the last step will then be a link to Despatch's create action, which will create the Despatch, empty the Cart and clear the session variable.
Does anyone know of a cleaner way of pulling this off?
Thanks in advance.
Franz
