Some basic concepts

  • Drupal
  • Core and Contrib modules

All nodes of any type are visible to users with “access content”. Node access and content access modules are necessary for fine- grained control on a node type and per node basis to hide various functionality you need hidden.

You get everything. Hiding interfaces that aren’t necessary in your use case is a non-trivial amount of time.

What is an entity?

  • An entity is an abstract object.
  • node, taxonomy, comment, user.
  • An entity type may do all of what a node did in

Drupal 5 and Drupal 6.

  • Revisions
  • Fields
  • Bundles
  • Access, URI, Theming,

View Modes

Entity controller classes can have public methods such as load() and delete(). Additionally, most entities define global methods using their standard Drupal namespace (module name) to allow

  • ther modules to use something not-object based:

node_save(), node_load().

You can define your own revision table for your custom entity, which you would need to save data in as well when you call your entity’s save method.

The Drupal 5 and 6 concept of “CCK” or custom fields was pushed into Drupal core, which means that all entities may contain fields. Good bye, Content Profile. Hello, Profile2!

Drupal Site Architecture

  • Entities will change how you architect,

engineer, and build Drupal web sites.

  • Architect - plan flexible and unique data

types.

  • Engineer - develop re-usable code.
  • Builder - utilize the tools that Entity API and

the developer provides to make quick changes to Views, Rules, Themes, etc...
