DualSelector

[SaarWolf]

I want to use the DualSelector-Widget with a many-to-many relation.

Model:

class Tag(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    tag = models.CharField(
        max_length=20,
        verbose_name=_("Tag"),
    )

class Page(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    description = models.CharField(
        _("description"), max_length=80, unique=True, blank=False
    )
    tags = models.ManyToManyField(Tag)
    ...

Form:

...
tags = forms.ModelMultipleChoiceField(
        label=_("tags"),
        queryset=Tag.objects.all(),
        widget=DualSelector(search_lookup="tags__icontains"),
    )
...

I get the widget - but no entries. The value is in the html but not shown in the widget.

...
 <select is="django-dual-selector" name="tags"  required form="id_pageform" id="id_tags" multiple>
                    <option value="5a8067b7-9555-4e58-b55e-7bddbf82a0ee">System</option>
 </select>
...

Btw: I tried the RichTextarea but there wasn't a connection between the control elements and the text area.

Any tip, what I've done wrong?

Please add a full example to the testapp and point me onto your fork. Take one of the provided examples as starting point.

does this have anything to do with the main question?

I tried to use the testapp. First installed the requirements.

As I tried npm install django-formset, I got the following output:

npm warn deprecated [email protected]: Modern JS already guarantees Array#sort() is a stable sort, so this library is deprecated. See the compatibility table on MDN: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort#browser_compatibility
npm warn deprecated [email protected]: See https://github.com/lydell/source-map-resolve#deprecated
npm warn deprecated @types/[email protected]: This is a stub types definition. cssnano provides its own type definitions, so you do not need this installed.

In the output of collectstatic i got:

It looks like that in the browser:

Btw: I tried the RichTextarea but there wasn't a connection between the control elements and the text area.

does this have anything to do with the main question?

No. I thought that maybe could be a hint.
