        return "%s -> %s" % (self.From, self.to)

    def __unicode__(self): # __str__ on Python 3

Answer 1

当您查看查询字典（例如request.POST）时，您会看到列表，因为HTML表单可以为同一个键提交多个值。

但是，手动构建数据字典时，应使用字符串而不是列表。

a = {u'From': 'Bangalore', u'userid': '50', u'choice':'(4,)', u'to':'Goa', u'from_date':'2016-10-20', u'to_date':'2016-10-23'}
abc = SaveTripForm(a)

Answer 2

实际上是request.POST数据的问题。 表格未验证，因为帖子数据值在LIST中。 对于这个问题，我们可以这样做 abc = SaveTripForm(a.dict())
