    ('Not any day', 'None'),
       )

closingDay = MultiSelectField(choices=DAYS)

Answer 1

当您指定默认= DAYS [7] [7] 时，您正在指定第8行的第8列的值，这显然不存在。你应该分配 默认= DAYS [7] [0]

Answer 2

实际上很容易，MultiSelectField 接受字符串数组或单个字符串作为 default。

本示例中的一些有效值是。

#Using choice value
closingDay = MultiSelectField(choices=DAYS, default=DAYS[7][0])
#Multiple value default
closingDay = MultiSelectField(choices=DAYS, default=['sunday', 'tuesday', 'wednesday', 'thursday'])
#Direct String
closingDay = MultiSelectField(choices=DAYS, default='thursday')
