Duplicated select2 input when rendering

See original GitHub issue

Issue Description

Looking at so many uncommented issues makes me not very hoping of fixing it anytime soon, but I’m facing a problem that I can’t seem to figure out. The select2 input is rendered twice, I get two search fields, specifically two of these:

<span class="select2-selection select2-selection--single" role="combobox" aria-haspopup="true" aria-expanded="false" tabindex="-1" aria-disabled="false" aria-labelledby="select2-id_form-0-producto-container">Busque productos

Captura de pantalla de 2020-10-30 11-14-35

This is my django code:

models.py
class Producto(models.Model):

    nombre_amistoso = models.CharField(
        max_length=40,
        help_text=_('Nombre amigable del producto.')
    )
    nombre_fabricante = models.CharField(
        max_length=60,
        help_text=_(
            'Nombre real del producto, tal como lo conoce el fabricante.'
        )
    )
    fabricante = models.ForeignKey(
        'Fabricante',
        on_delete=models.SET_NULL,
        blank=True,
        null=True
    )
    referencia = models.CharField(
        max_length=25,
        help_text=_('Referencia del fabricante.')
    )

forms.py
class ProductoWidget(s2forms.ModelSelect2Widget):
    """ Widget especial creado con libreria django-select2.
    Busca según los campos especificados en serach_fields. """

    search_fields = [
        "nombre_amistoso__icontains",
        "nombre_fabricante__icontains",
        "referencia__icontains",
    ]


class ArticuloForm(forms.ModelForm):
    """ Este formulario se utiliza para agregar articulos a la pizarra. """

    class Meta:
        model = Articulo
        fields = ['producto', 'unidades']
        widgets = {
            "producto": ProductoWidget(
                {'data-language': 'es',
                 'data-placeholder': 'Busque productos',
                 'data-width': '100%',
                 }
            ),
        }

views.py

def NuevaNota(request):
    ArticuloFormset = formset_factory(ArticuloForm)
    if request.method == "POST":
    # bunch of code

    else:
        articulos = ArticuloFormset()
        nota = NotaForm()
        context = {
            'articulos': articulos,
            'nota': nota
        }
        return render(request, "gestion/anotar.html", context)

The inputs work perfectly, they search in the fields they have to. Only they render in duplicate. Also, the data-language attribute seems to not be taking any effect (still in english).

I hope @codingjoe can take a look at the open issues anytime soon. Thanks a lot for taking over, let me know If I can be helpful in any manner, I’d love to. J.

update: I add also the html template.

Wow, cool, thanks @CleitonDeLima for sorting this out. I love it when problems solve themselves, still I am sorry took me so long to answer. I kind of got married this weekend, and therefore was preoccupied.

In case this helps someone: obviously it was my fault. I opened a block before closing the previous one in the django template. I basically nested by mistake one block inside another (which is not how django works). Big thanks to @CleitonDeLima who reviewed my code and pointed it out 🎉
