So I am trying to use autocomplete-light 3.1.8 and following this tutorial. Now I have a model called "Equipment" with a many-to-many field "used_for_tests". Following the tutorial, I set the following code up but had this no reverse match error. This happens when I tried to add a new equipment
in models.py:
class Equipment(models.Model):
asset_number = models.CharField(max_length = 200, null=True, unique = True)
used_for_test = models.ManyToManyField(Tests)
class EquipmentForm(ModelForm):
helper = FormHelper()
helper.layout = Layout(
Div(
Div('asset_number',
css_class='col-sm-4'),
Div(
'used_for_test',
ButtonHolder(
Submit('save', 'Save')
), css_class='col-sm-4'),
css_class='row-fluid'),
)
class Meta:
model = Equipment
fields = ['asset_number', 'used_for_test']
widgets = {'used_for_test': autocomplete.ModelSelect2Multiple(url='tests')
}
)
urls.py:
url(
r'^tests-autocomplete/$',
TestsAutocomplete.as_view(),
name='tests',
),
views.py:
class TestsAutocomplete(autocomplete.Select2QuerySetView):
def get_queryset(self):
# Don't forget to filter out results depending on the visitor !
if not self.request.user.is_authenticated():
return Tests.objects.none()
qs = Tests.objects.all()
if self.q:
qs = qs.filter(name__istartswith=self.q)
return qs

Exception Type: NoReverseMatch at /calbase/equipment/new/
Exception Value: Reverse for 'tests' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []
But as showed here, in models it points to "tests" and that's right the name I gave in urls. Why there is a no reverse match problem?
Also, the "Using autocompletes outside the admin" part in the tutorial is confusing.
{% block footer %}

what are those for?
Thanks guys
