dreizwo's sandbox: cttree

This module provides the opportunity to order content types in parent-child relations. You can create a simple structure of content-types (like menu-links) calling /admin/structure/ctree.
Steps for configuration:
1. Enable the Auto Menu D7 Port Module ( I will commit this as a own project soon)
2. Enable the ContentTree Module
3. Goto /admin/structure/cttree and add enable checkbox 'Enable autochildnode creation'
4. Add some content-types by calling /admin/structure/cttree/add (you can add them several times considering some contraints explained later)
5. Build you structure
6. Ensure Auto-Menu settings have been configured correctly for all first level entries of you structures
7. Save configurations
8. Create new content of a first level element.

=> the complete structure will be created at once.

A simple (poorly conceived) example:
You got the content-types : 'store', 'articles', 'address', 'staff', 'shoes', 'pants', 'shirt'
You can create the structure with ContentTree module:
-store
--address
--staff
---address
--articles
---shoes
---pants
---shirts
Let's say you have a custom menu, too, called menu-stores. You have configured content-type 'store' as a auto-menu child for menu-stores before. If you now create a new 'store' all others content-types will be created and linked in the correct order and parent-child relation, too: one 'address' as child for the 'store', one 'staff' as a child of 'store', one 'address' as child for 'staff' a.s.o.

Additionally there's a possiblility to set a count for each level and content-type. This count will be used to create each level (an from there all sublevel) several times. According to the sample above ....
-store (1)
--address (1)
--staff (3)
---address (2)
--articles (1)
---shoes (10)
---pants (5)
---shirts (4)
.... these count settings would create 1 store, 1 address as child of store 3 times staff with two times address each, 1 articles, 10 shoes, 5 pants and 4 shirts - all with one click!

Additionally you can enable one more feature: Check 'Enable node validation' - but handle with care. This option will:
> disable the possiblity to create new nodes if they are not in the correct structure
>> if you still want to be able to create e.g. a new 'page' and you have checked this option, you have to add it on first level, too, otherwise a error message will appear...
> enable usage of max count setting
>> max count represents the maximum number of content-types that can be created manually.
>>> 0 = unlimeted creation allowed (the default)
>>> n = it can only be created once (e.g. setting 'address' max to 1 as child of 'store' implicates that you no longer can create additional addresses as child of stores if there's still one.)

This module depends on the Auto Menu D7-Port see #1138946: Auto Menu - D7 Port.

Addtional descriptions will follow if needed.

personal note:
This module contains a couple of small manageable and clear interfaces and classes. I tried (and hope managed as well) to prevent from unsightly code in one large php file - as is unfortunately a common practice in many other modules. But's it's a first draft - improvements will be done - suggestions are naturally welcome.
