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

[Adam Summers]

Hi!

Thanks very much for your help!

So now for reference, my class now looks like
> mytemplate = grok.PageTemplateFile(filename='...')
>> class showData(grok.Form):
>>        grok.context(Restaurant)
>>        grok.name('vlh')
>>
>>        form_fields = grok.Fields( f_date = schema.Date 
>> (title=u'Date'),
>>                 f_daycount = schema.Int(title=u'Number of Days'))
>>
>>        @grok.action('Calculate!')
>>         def calc(self, **data):
>>                 self.mylist =  self.context.getStats(data 
>> ['f_date'],'BREAKFAST',2)
>> 		return(mytemplate.render(self))
[...]

Regards,
Adam
