Django_filters with django-autocomplete-light

Question

I am using django-autocomplete-light with django_filters. I looked django-filter with django autocomplete-light, but my autocomplete doesn't work.

Models.py:

class ProfessionalDevelopment(models.Model):
   Name = models.CharField("Professional Development", max_length=20,default = "None")
   ProfessionalExperience = models.ManyToManyField(Person, through='PersonToProfessionalDevelopment')

class PersonToProfessionalDevelopment(models.Model):
   PersonID = models.ForeignKey(Person,  on_delete=models.CASCADE)
   ProfID = models.ForeignKey(ProfessionalDevelopment,  on_delete=models.CASCADE)
   Desc = models.CharField("Professional Development Description", max_length=30, default="None")

Views.py:

class ProfessionalDevelopmentAutocomplete(autocomplete.Select2QuerySetView):
 def get_queryset(self):
    qs = ProfessionalDevelopment.objects.all()
    if self.q:
        qs = qs.filter(name__istartswith=self.q)
    return qs

urls.py

urlpatterns = [url(r'^search/ProfessionalDevelopment-autocomplete/$', ProfessionalDevelopmentAutocomplete.as_view(),
    name='ProfessionalDevelopment-autocomplete']

Filters.py:

ProfessionalDevelopment = django_filters.CharFilter(name='professionaldevelopment__Name', lookup_expr='icontains',
                                                    widget=autocomplete.ModelSelect2(url='RSR:ProfessionalDevelopment-autocomplete'))

I got an error says 'list' object has no attribute 'queryset'. Then I changed the code to autocomplete.Select2 instead of autocomplete.ModelSelect2 (according to https://github.com/yourlabs/django-autocomplete-light/issues/763). Although no error, but I can not type in the text input box. Could someone help me? Thanks

You wan to filter model ProfessionalDevelopment against it's name. You need to modify in these steps:

1. Complete str or Unicode on model ProfessionalDevelopment otherwise the option shows on filter will be id.

   class ProfessionalDevelopment(models.Model):
      Name = models.CharField("Professional Development", 
      max_length=20,default = "None")
      ProfessionalExperience = models.ManyToManyField(Person, 
      through='PersonToProfessionalDevelopment')
   
      def __unicode__(self):
          return self.name
   

2. Change filter field of ProfessionalDevelopment:

   ProfessionalDevelopment = django_filters.ModelChoiceFilter(
       queryset=ProfessionalDevelopment.objects.all(), 
       widget=autocomplete.ModelSelect2(url="yourcompleteurl")
   )
   

these steps should address you problem. Don't forget add {{ form.media }} in your template.
