Question

我创建了一个带有django-selectable小部件的ModelForm：

class SomeRequestForm(forms.ModelForm):

created_by = selectable.AutoCompleteSelectMultipleField(lookup_class=SomeGroupUser,
    label='',
    required=True,
    widget=selectable.AutoCompleteSelectMultipleWidget)

我的查询：

class SomeGroupUser(ModelLookup):
model = User
search_fields = (
    'username__icontains',
    'first_name__icontains',
    'last_name__icontains',
)
filters = {'is_active': True,  }

def get_item_label(self, item):
    # Display for choice listings
    return u"%s, gebruikersnaam: %s" % (item.get_full_name(), item.username)

在我看来：

 if request.method == "POST":
           some_request_form = SomeRequestForm(request.POST, current_user=request.user, 
            , prefix="peer", )
 else:
        some_request_form = SomeRequestForm(current_user=request.user,prefix="peer")

这给出了以下错误：

Cannot assign "[<User: Test Test>]": "Some.created_by" must be a "User" instance.

然后我尝试循环request.POST列表，并为每个用户创建一个表单并获取用户对象：

if request.method == "POST":
        post_values = request.POST.copy()

        created_by_users = request.POST.getlist('peer-created_by_1')

        for created_by_user in created_by_users:

            created_by_user = User.objects.get(pk=5)
            post_values['peer-created_by_1'] = created_by_user

            peerassessment_form = PeerassessmentRequestForm(post_values, current_user=request.user, prefix="peer", )

但后来我收到了这个错误：

int() argument must be a string or a number, not 'User'

然后我尝试将post值更改为用户的pk并收到此错误：

Cannot assign "[<User: Test Test>]": "Some.created_by" must be a "User" instance.
