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.rset.get_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)
