视图(也包括表格)

from dal import autocomplete

       # if not self.request.user.is_authenticated():
        #    return Country.objects.none()

        qs = Country.objects.all()

        if self.q:
            qs = qs.filter(name__istartswith=self.q)

        return qs

class Form_country(forms.ModelForm):
    class Meta:
       model = Country
       fields = ('name', 'code2l')
       widgets = {
          'name': autocomplete.ModelSelect2Multiple(
            'country-autocomplete'
           )
       }

class UpdateView(generic.UpdateView):
    model = Country
    form_class = Form_country
    template_name = 'fr/public/monformulaire.html'
    success_url = reverse_lazy('select')


    def get_object(self):
        return Country.objects.first() 

推荐答案

我遇到了同样的问题.这里的问题是小部件.试图将其修复很长时间.对我有用的唯一方法是更改​​表单的小部件.

I had the same issue. The problem here is with the widget. Tried to fix it for very long. The only way in worked for me was changing form's widget.

如果没关系，您可以改用autocomplete.ListSelect2，它对我有用.

If it doesn't matter that much you can use autocomplete.ListSelect2 instead, it worked for me.

所以尝试一下:

class Form_country(forms.ModelForm):
    class Meta:
       model = Country
       fields = ('name', 'code2l')
       widgets = {
          'name': autocomplete.ListSelect2(
            'country-autocomplete'
           )
       }

实际上，您可以尝试使用其他任何自动填充小部件，并查看其是否有效

Actually you can just try any other autocomplete widget and see weather it works
