django-autocomplete-light error = 'list' object has no attribute 'queryset'

Question

i am new on django and i need your help, trying since many days to understand django-autocomplete-light, after setup my test, http://192.168.0.108:8000/country-autocomplete/

Answer 1

Here is my implementation, where I used it to suggest similar names that are already present in a model

IMPORTANT: After you must have done all these, don't forget to run python manage.py collectstatic. Also note that you wish to include a placeholder in your form field you have to do it with data-placeholder in the widget autocomplete widget.

When you run it, you'll see this message

Found another file with the destination path 'admin/js/jquery.init.js'. It will be ignored since only the first encountered file is collected. If this is not what you want, make sure every static file has a unique path.

This is the reason the documentation states here that you must place dal and dal_select2 before django.contrib.admin in your INSTALLED_APPS

models.py

from django.db import models

class Patient(models.Model):
    name = models.CharField(max_length=100)
    stable = models.BooleanField(default=False)

views.py

from django.db.models import Q
from dal import autocomplete

class NewName(autocomplete.Select2QuerySetView):
    """Suggest similar names in form"""
    def get_queryset(self):
        qs = People.objects.filter(stable=True)
        if self.q:
            query = Q(name__contains=self.q.title()) | Q(name__contains=self.q.lower()) | Q(name__contains=self.q.upper())
            qs = qs.filter(query)
        return qs

urls.py

from django.urls import path
from . import views
urlpatterns = [
    path('new-name/', views.NewName.as_view(), name='new_name_autocomplete'),
]

forms.py

class PatientForm(forms.ModelForm):
    class Meta:
        model = Patient
        fields = ["stable", "name"]

        widgets = {
            "name" : autocomplete.ModelSelect2(url=reverse_lazy('new_name_autocomplete'), attrs={'class' : 'form-control', 'data-placeholder' : "Name"}),

I had to modify dal/widgets.py and comment out the queryset filtering as shown below. It seems to be a bug or something. The issue has been raised here. But if you're using autocomplete.ListSelect2() as your widget, then there's no need for that.

class QuerySetSelectMixin(WidgetMixin):
    """QuerySet support for choices."""

    def filter_choices_to_render(self, selected_choices):
        """Filter out un-selected choices if choices is a QuerySet."""
        # self.choices.queryset = self.choices.queryset.filter(
        #     pk__in=[c for c in selected_choices if c]
        # )

Answer 2

I you create the widget in __init__(), then this work-around of issue #790 helps:

form.fields['name'].widget.choices = form.fields['name'].choices

Answer 3

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.

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

So try this:

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

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