按照错误提示信息，找到以下代码

    def render(self, name, value, attrs=None):
        if DJANGO_11:
            input_html = [ht for ht in super(AdminSplitDateTime, self).render(name, value, attrs).split('
') if ht != '']
            # return input_html
            
            return mark_safe('<div class="datetime clearfix"><div class="input-group date bootstrap-datepicker"><span class="input-group-addon"><i class="fa fa-calendar"></i></span>%s'
                             '<span class="input-group-btn"><button class="btn btn-default" type="button">%s</button></span></div>'
                             '<div class="input-group time bootstrap-clockpicker"><span class="input-group-addon"><i class="fa fa-clock-o">'
                             '</i></span>%s<span class="input-group-btn"><button class="btn btn-default" type="button">%s</button></span></div></div>' % (input_html[0], _(u'Today'), input_html[1], _(u'Now')))
        else:
            return super(AdminSplitDateTime, self).render(name, value, attrs)

    def format_output(self, rendered_widgets):
        return mark_safe(u'<div class="datetime clearfix">%s%s</div>' %
                         (rendered_widgets[0], rendered_widgets[1]))

input_html就是报错的代码，因为input_html里只有一个元素，从报错信息里也能找到input_html的值如下：

input_html = [ht for ht in super(AdminSplitDateTime, self).render(name, value, attrs).split('
') if ht != '']

修改后代码：

input_html = [ht for ht in super(AdminSplitDateTime, self).render(name, value, attrs).split('/><') if ht != '']
input_html[0] = input_html[0] + "/>"
input_html[1] = "<" + input_html[1]

即可。
