Définir l'interface utilisateur avec des vues

=============================================

`LAX` provides out-of-the-box a web interface that is generated from

the schema definition: entities can be created, displayed, updated and

deleted. As display views are not very fancy, it is usually necessary

to develop your own.

With `LAX`, views are defined by Python classes. A view includes :

- an identifier (all objects in `LAX` are entered in a registry

  and this identifier will be used as a key)

- a filter to select the resulsets it can be applied to

`LAX` provides a lot of standard views, for a complete list, you

will have to read the code in directory views (XXX improve doc).

For example, the view named ``primary`` is the one used to display

a single entity.

If you want to change the way a ``BlogEntry`` is displayed, just

override the view ``primary`` in ``BlogDemo/views.py`` ::

  from ginco.web.views import baseviews

  class BlogEntryPrimaryView(baseviews.PrimaryView):

      accepts = ('BlogEntry',)

      def cell_call(self, row, col):

          entity = self.entity(row, col)

          self.w(u'<h1>%s</h1>' % entity.title)

          self.w(u'<div>%s</div>' % entity.publish_date)

          self.w(u'<div>%s</div>' % entity.category)

          self.w(u'<div>%s</div>' entity.content)
