Question

我在views.py中有以下代码，我希望获得完整的人员列表。

def all_json_persons(request, state):
    print "current_state--" + str(state)
    current_state = State.objects.get(id=state)
    print "current_state--" + str(current_state)
    districts = District.objects.all().filter(state=state)
    print "districts--" + str(districts)
    personsList = []
    for current_district in districts:
       villages = Address.objects.all().filter(district=current_district) 
       for current_village in villages:
          persons = Person.objects.all().filter(address=current_village)
          print "persons--" + str(persons)
          personsList.append(persons)  
    print "personsList--" + str(personsList)
    json_persons = serializers.serialize("json", personsList)
    print "json_persons--" + json_persons
    return HttpResponse(json_persons, mimetype="application/javascript")

它在终端上返回以下结果：

current_state--2
current_state--Odisha
districts--[<District: Jagatsighpur>, <District: Koraput>]
persons--[<Person: Annnn Ppppp>, <Person: Rrrrr Jeeee>, <Person: Raaaaa Jennn>, <Person: Annnnn Saaaa>]
persons--[<Person: Laaaa Sikaka>, <Person: Lingram  Azzzzz>]
personsList--[[<Person: Annnn Ppppp>, <Person: Rrrrr Jeeee>, <Person: Raaaaa Jennn>, <Person: Annnnn Saaaa>], [<Person: Laaaa Sikaka>, <Person: Lingram  Azzzzz>]]
**[15/Dec/2012 21:05:42] "GET /state/2/all_json_persons/ HTTP/1.1" 500 75201**

我无法弄清楚为什么以下代码行无法在上述情况下工作：

json_persons = serializers.serialize("json", personsList)

但是，如果我将上述行中的personsList替换为人。它运作良好。但我想要一个州的整个人员名单。请帮忙。

Django的序列化程序用于序列化查询集。如果要序列化其他内容，请将其转换为基本类型，例如values()或values_list()然后使用普通的JSON机制来序列化它。

Django - JSON serializers.serialize无效
