Having multiple relations in edit/create form
In my app user can create something called Package. Package has to have following
- Model
- Books(which in turn belong to Model. When selecting Model, user can also select multiple Books for Model)
- Contact
First thought was having wizard, i.e. having 3 steps:
- Select Model
- Select Books for each Model
- Select Contacts
But afaik this doesn't work well if user can not only create an entity, but also edit it.
Is there some pattern or examples of how to manage this kind of complex relationships and dependent entities in a form?
Attached are mockups for current iteration I came up with. So far creation of Package is split in to two different screens. On one Models and Books are selected, and Contacts + additional data on another. But I don't really see how a user can easily edit data in this screen configuration, i.e. clicking on "Edit Package" in Package list will probably open first screen, and won't give full overview.
