Missing SuluAdminBundle Documentation

[alexander-schranz]

The SuluAdminBundle configuration is currently missing (bundles/admin/index.rst):

There is already internal ticket on our side but we want to create the following 3 pages (including subpages) around the AdminBundle

1. Admin Class (bundles/admin/admin-class.rst)

• Creating a Admin Class
• Add Navigation Context
• Basic Docs what ViewBuilders are (list of ViewBuilders)
• 1.1 ViewBuilders (list to own docs bundles/admin/view-builders/*)
  • Docs for Every ViewBuilder and its special options. Always a simple and complex example
• Security Contexts
• Config & Config Keys
• Override & Extend existing Admin classes (ViewBuilder, Navigation, ...)

2. List (bundles/admin/list.rst)

• List Path Configuration (how to add a new directory containing forms)
• Documentation List.xml simple property list (completly without any entity)
• 1.1 Transformers (list to own docs bundles/admin/list-transformers/*)
• Documentation List.xml usage as a query builder with an entity
• Listmetadatavisitor

3. Form (bundles/admin/form.rst)

• Form Path Configuration (how to add a new directory containing forms)
• Form xml documentation equivalant to current template documentation in the book.
• FormMetadataVisitor

3.1 Field Types (list to own docs bundles/admin/field-types/*)

- Documentation for every FieldType (simple example, complex example with all parameters, JSON format e.g. `{"ids": [1,2,3], "displayOption":"left"}`. Example of serialization on an entity. Add crosslink between content type and field type. Document field type specific parameters `request_parameters`, `resource_store_properties_to_request`, ... only in field type not in content type.Focus content type documentation on website development with real world examples
