In django_select2, the field_id parameter is getting not passed in ajax url

Question

While I am using django_select2, the field_id parameter is not getting passed to get URL select2/fields/auto.json.

Due to this, it throws 404 error.

Is there any configuration I am missing?

python3.6, django2.1 and django_select2 LIB_VERSION = v4.0.5 django_select2-6.3.1.dist-info

All are latest versions only.

I am not sure where is the problem but I can see that GET URL select2/fields/auto.json is called without field_id. When I manually execute it with field_id with the key generated, I am getting the proper results.

Answer 1

Here is the maintainer of django-select2. Saldy we no longer maintain version 4. This is a really old version and in version 5 we did a complete rewrite. That solved a lot of issues. Maybe this one too. I highly suggest to update to the latest version. Especially if you are using Django 2.1 and Python 3.6.

You might be missing the JS that grabs the field ID and adds it to the request -- make sure you have {{ form.media.js }} in the view, or initialize the field manually using $('.django-select2').djangoSelect2();

See the docs here: https://django-select2.readthedocs.io/en/latest/django_select2.html#javascript
