:mod:`waeup.university.department` -- Departments
*************************************************

.. module:: waeup.university.department

Components that represent university departments.

:Test-Layer: unit

Before we can create departments, we have to grok the :mod:`waeup`
package. This happens automatically in real-world use:

    >>> import grok
    >>> grok.testing.grok('waeup')


Content Classes (models and containers)
=======================================


:class:`Department`
-------------------

.. class:: Department(title=u'Unnamed Department'[, title_prefix=u'department' [, code=u"NA"]])

   Create a representation of a university department:

     >>> from waeup.university.department import Department
     >>> mydept = Department()
     >>> mydept
     <waeup.university.department.Department object at 0x...>

   Another way to create :class:`Department` instances is by asking
   for a factory called ``waeup.Department``. This way we can create a
   department without importing a class:

     >>> from zope.component import createObject
     >>> mydept = createObject(u'waeup.Department')
     >>> mydept
     <waeup.university.department.Department object at 0x...>

   :class:`Department` instances have the attributes required by the
   `IDepartment` interface:

     >>> from waeup.interfaces import IDepartment
     >>> IDepartment.providedBy(mydept)
     True

     >>> from zope.interface.verify import verifyObject
     >>> verifyObject(IDepartment, mydept)
     True


   .. attribute:: title

      (string) The title of a department.

      Each department has a title:

        >>> mydept.title
        u'Unnamed Department'


   .. attribute:: title_prefix

      (string) The prefix of a department.

      Each department has a title prefix, which specifies the kind of
      institution:

        >>> mydept.title_prefix
        u'department'


   .. attribute:: code

      (string) An internally used unique code string.

      Each department holds a code, which might be a shortcut or
      abbreviation of the real department name. By default the code is
      ``NA`` (=not assigned):

        >>> mydept.code
        u'NA'


   .. attribute:: courses

      (ICourseContainer instance) A container for courses.

      Each department has a courses container:

        >>> mydept.courses
        <waeup.university.coursecontainer.CourseContainer object at 0x...>
