    views.py

def deepsearch(request):
if request.method == 'POST':    
    deepsearchForm = DeepSearchForm(request.POST)

    if deepsearchForm.is_valid():

问题： forms定义控件，在HTML显示正常。 多选框的值，如果不选择，则 is_valid 返回的是True 有任一个选择后，views.py里绑定值出现问题。is_valid 返回的是False

把 request.POST打印出来，发现：根本没有checkbox选项和值在里面。 如下： <QueryDict: {u'search': [u'\u641c\u7d22'], u'select_level': [u'1'], u'log_level': [u''], u'end_date_0': [u'2019-09-09'], u'select_start': [u'1'], u'end_date_1': [u'19:39:29'], u'select_end': [u'1'], u'start_date_0': [u'2019-09-09'], u'start_date_1': [u'19:39:29'], u'select_type': [u'1'], u'csrfmiddlewaretoken': [u'dJO0EeSvsdqwxaJEvqWhv9OWJwkFa6t6'], u'select_ip': [u'1']}>

后来采用：request.POST.getlist('server_ip_name') 这样去获取，是可以取到的。 由于forms里的取值，我需要多次访问与响应间带回原来的值。所以需要直接把request.POST的值绑定给forms，请问哪里处理得有问题。

谢谢！
