mutiple arugment with date range in filter with object query set in django?

Question

I'm passing multiple argument in a filter, but when I try to pass date range it's not working, and showing an error : I wrote the following code for that:

where_con = {}
for k in model_k_j:
    type_val = type(model_k_j[k])
    if type_val== dict:
        print "dictonary type"
        where_con[k] =  medical_home_last_visit__range=["2012-1-1","2013-11-21" ]
    else:
        col_name.append(k)
        where_con[k] =  model_k_j[k] 

# **where_con {unpack tuple}
print where_con
qs_new = model_obj.objects.filter(**where_con)

Can you suggest what is wrong in that?

范围应该是日期时间对象的元组而不是字符串，请检查引用： https : //docs.djangoproject.com/en/1.6/ref/models/querysets/#range
