Question

我在基于类的视图（创建，更新，删除视图）中使用django-select2 在CreateView中，我在窗体视图中使用form_class。在这种形式下，我使用小部件来选择相关对象。而且我需要通过created_user（所有者）过滤这些对象。如何将方案中的当前用户传递给小部件ModelSelect2MultipleWidget类？

forms.py：

class AccountSearchFieldMixin(object):
    search_fields = [
        'login__icontains',
        'password__icontains',
        'phone__icontains',
    ]


class AccountSelect2TagWidget(AccountSearchFieldMixin, ModelSelect2MultipleWidget):
    model = VkAccount
    queryset = VkAccount.objects.exclude(proxy__isnull=True)

    def create_value(self, value):
        self.get_queryset().create(name=value)


class TaskVkInvitationsFriendsSearchForm(forms.ModelForm):
    # country = ModelChoiceField(Countries.objects.all(), empty_label=None, label='Страна')f

    class Meta:
        model = TaskVkInvitationsFriendsSearch
        exclude = ['type', 'date_creation', 'date_update', 'maintask', 'invited_friends']
        widgets = {
            'accounts': AccountSelect2TagWidget,
            'cities': CitiesSelect2TagWidget,
            'scheduler_data': forms.HiddenInput,
            # 'country': CountrySelect2TagWidget
        }

    def __init__(self, *args, **kwargs):
        self.owner = kwargs.pop('owner')
        super(TaskVkInvitationsFriendsSearchForm, self).__init__(*args, **kwargs)

views.py：

class BaseTaskMixin:
    model = TaskVkInvitationsFriendsSearch
    form_class = TaskVkInvitationsFriendsSearchForm
    success_url = reverse_lazy('vk_bot_tasks_list')
    template_name = 'vk_bot/create_task.html'


class TaskCreateView(BaseTaskMixin, CreateView):

    def form_valid(self, form):
        model = form.save(commit=False)
        t = Task()
        t.save()
        model.maintask = t
        model.save()
        form.instance.owner = self.request.user
        return super(TaskCreateView, self).form_valid(form)

我需要使用search_fields更改mixin并将其推送到data_view参数：

forms.py：

class AccountSearchFieldMixin(object):
    search_fields = [
        'login__icontains',
        'password__icontains',
        'phone__icontains',
    ]

    def __init__(self, *args, **kwargs):
        kwargs['data_view'] = 'account_json'
        super(AccountSearchFieldMixin, self).__init__(*args, **kwargs)

创建带有select2的json答案请求的视图。

views.py：

class AccountJsonView(AutoResponseView):

    def get_queryset(self):
        qs = super().get_queryset()
        return qs.filter(owner=self.request.user)

最后一次更改urls.py：

path('fields/account.json', login_required(views.AccountJsonView.as_view()), name="account_json"),

Django-select2按所有者（相关用户）过滤窗口小部件数据
