−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)
