Multiple Selection, pre-populate choices

[apishark]

I have created a 'Custom Field' named 'Group' with a 'Type' of 'Multiple Selection' with a 'Content Types' of 'Circuits >provider'.

If I inspect the HTML in chrome, I can see:

I am trying to populate the choices.

I have the following receiver configured.

@receiver(models.signals.post_init, sender=Provider)
def my_group(sender, instance, **kwargs):
GROUP_CHOICES = [grp.name for grp in Group.objects.all()]
instance.custom_field_data['Group'] = SelectMultiple(choices=GROUP_CHOICES)

No choices appear at circuits/providers/add/ 'Custom Fields',' Group*'

What do I need to change in order to pre-populate the choices?

Please can you clarify:

• What is generating this form: a custom script, a plugin, or something else?
• Where are you putting this signal receiver code?
• Where does this "Group" model come from?

No choices appear at circuits/providers/add/ 'Custom Fields',' Group*'

Modifying the forms of built-in Netbox views is not supported.

As I understand it, Netbox 3.2 will let you create custom fields which reference other database objects. You might need to wait for that.

1. Plugin
2. plugin/models.py
3. Group.objects.all() is populated from the UI at admin/auth/group/

GROUP_CHOICES looks like this.

(I have covered providers names)

I have not modified the built-in Netbox form. I added the custom field at /extras/custom-fields/

Hope this helps.
