[Grok-dev] Using templates on forms with multiple actions?

[Souheil CHELFOUH]

you can define templates and call them:

mytemplate = grok.PageTemplateFile(filename='...')

and to call it :

mytemplate.render(self)
the form will then be the "view" of the template
you can set your lists before calling the template

self.mylist = self.context.getVLHData(data['f_date'], 'BREAKFAST',
data['f_daycount'])
mytemplate.render(self)

and in your template:
<tal:loop repeat="line view/mylist">...</tal:loop>
