在Flask中将表单POST对象转换为适合mongodb的表示形式

>>> from werkzeug.datastructures import ImmutableMultiDict>>> imd = ImmutableMultiDict([('default', u''), ('required', u'on'), ('name', u'short_text'), ('name', u'another'), ('submit', u'Submit')])>>> imd.to_dict(flat=False)>>> {'default': [''], 'name': ['short_text', 'another'],'required': ['on'],'submit': ['Submit']}

.to_dict(flat=False)
