Contact
*******

.. highlight:: python

The new version of the contact app (branch ``2953-ember``) stores multiple email
addresses, phone numbers and postal addresses for each contact.

.. note:: The ``email`` address in the ``User`` is not indexed by ElasticSearch.
          All email addresses should be stored in the ``ContactEmail`` model
          (migration 0006_auto_20180417_0736_ handles this automatically).

Model
=====

Define the contact model in ``settings/base.py`` (or in ``example_app/base.py``
for an app)::

  CONTACT_MODEL = "contact.Contact"

To get the actual contact model, create a ``get_contact_model`` function
(perhaps in ``models.py``) e.g::

  from django.apps import apps
  from django.conf import settings

  def get_contact_model():
      return apps.get_model(settings.CONTACT_MODEL)

Templates and Mixins
====================

.. tip:: All projects which use the ``contact`` app should provide a *detail*
         URL named ``contact.detail``.

``ContactDetailMixin``
----------------------

::

  from braces.views import LoginRequiredMixin, StaffuserRequiredMixin
  from django.views.generic import DetailView, TemplateView

  from contact.views import ContactDetailMixin

  class ContactDetailView(
      LoginRequiredMixin,
      StaffuserRequiredMixin,
      ContactDetailMixin,
      BaseMixin,
      DetailView,
  ):
      pass

::

  from .views import ContactDetailView

  re_path(
      r"^contact/(?P<pk>\d+)/$",
      view=ContactDetailView.as_view(),
      name="contact.detail",
  ),

``test_view_perm.py``::

  from contact.tests.factories import UserContactFactory

  @pytest.mark.django_db
  def test_contact_detail(perm_check):
      user_contact = UserContactFactory()
      url = reverse("contact.detail", args=[user_contact.contact.pk])
      perm_check.staff(url)


.. tip:: The ``example_contact/templates/example/contact_detail.html`` example
         template shows an example of how to use the two contact detail views::

           {% include 'contact/contact_detail.html' %}
           {% include 'contact/contact_detail_multi.html' %}

``ContactListMixin``
--------------------

::

  from contact.views import ContactListMixin

  class ContactListView(
      LoginRequiredMixin,
      StaffuserRequiredMixin,
      ContactListMixin,
      BaseMixin,
      ListView,
  ):
      template_name = "example/contact_list.html"

.. tip:: We also have a ``contact/templates/contact/_contact_list.html`` which
         can be included in your own templates if required::

           {% include 'contact/_contact_list.html' %}

::

  re_path(
      r"^contact/$",
      view=ContactListView.as_view(),
      name="contact.list"
  ),

::

  @pytest.mark.django_db
  def test_contact_list(perm_check):
      url = reverse("contact.list")
      perm_check.staff(url)

.. _user_contact_redirect_view:

``UserContactRedirectView``
---------------------------

This is a standard view which redirects from a user ``pk`` to a contact detail
view.  It is used by the ``app-gdpr``.

::

  from django.views.generic import RedirectView

  class UserContactRedirectView(RedirectView):

      permanent = False

      def get_redirect_url(self, *args, **kwargs):
          pk = kwargs["user_pk"]
          contact = Contact.objects.get(user__pk=pk)
          return reverse("contact.detail", args=[contact.pk])

::

  from .views import UserContactRedirectView

  re_path(
      r"^user/(?P<user_pk>\d+)/redirect/$",
      view=UserContactRedirectView.as_view(),
      name="user.redirect.contact",
  ),


Search
======

To create a simple contact search::

  from contact.search import ContactIndex
  from search.views import SearchViewMixin

  class SearchView(LoginRequiredMixin, StaffuserRequiredMixin, SearchViewMixin):

      INDEX_CHOICES = (("contact", "Contact"),)
      INDEX_CLASSES = {"contact": ContactIndex}

::

  re_path(
      r"^example/search/$",
      view=SearchView.as_view(),
      name="project.search",
  ),

.. tip:: This is using the standard URL name for a site wide search i.e.
         ``project.search``.
