我有以下功能，def facebooktest(request): fb_value = ast.literal_eval(request.body) fb_foodies = Foodie.objects.filter(facebook_id__in = fb_value.values()) for fb_foodie in fb_foodies: state = request.user.relationships.following().filter(username = fb_foodie.user.username).exists() userData = { 'fbid': fb_foodie.facebook_id, 'followState': int(state), }基本上我正在檢查我的django應(yīng)用程序上有哪些用戶的Facebook朋友。如果是，則返回followState。followState基本上返回1或0。如果用戶已經(jīng)在我的Django應(yīng)用程序上關(guān)注他們，則返回1；如果用戶在我的Django應(yīng)用程序上未關(guān)注其Facebook朋友，則返回0。我想將json類型字典返回給該用戶，如下所示：[{fbid:222222222222, followState: 0}, {fbid:111111111111, followState: 1}, {fbid:435433434534, followState:1}]

def facebooktest(request):
fb_value = ast.literal_eval(request.body)
fb_foodies = Foodie.objects.filter(facebook_id__in = fb_value.values())
response = []
for fb_foodie in fb_foodies:
state = request.user.relationships.following().filter(username = fb_foodie.user.username).exists()
userData = {
'fbid': fb_foodie.facebook_id,
'followState': int(state),
}
response.append(userData)
return json.dumps(response)

我認(rèn)為您正在尋找這個：
return HttpResponse(simplejson.dumps(response_dict), mimetype='application/json')
其中“ response_dict”將是您的字典。

django.forms.models包中有一個用于該功能的模型：model_to_dict
from django.forms.models import model_to_dict
model_to_dict(your_model, fields=[], exclude=[])
從幫助中：
model_to_dict(instance, fields=None, exclude=None)
Returns a dict containing the data in ``instance`` suitable for passing as
a Form's ``initial`` keyword argument.
``fields`` is an optional list of field names. If provided, only the named
fields will be included in the returned dict.
``exclude`` is an optional list of field names. If provided, the named
fields will be excluded from the returned dict, even if they are listed in
the ``fields`` argument.
