NestedTabularInline drag-and-drop?

[globophobe]

Thanks for the great library! NestedStackedInline drag-and-drop works great.

NestedTabularInline drag-and-drop doesn't seem to work. The first level is fine. However, subsequent levels of nesting don't respond.

Hmm. We have extensive unit tests for drag-and-drop on NestedTabularInline, and those run on all django versions from 1.8 to 2.0. Is there anything unusual about your django admin setup? Additional admin extensions, ModelAdmin class mixins, or custom templates?

[globophobe]

I disabled everything possible to see if there was a conflict. There are no custom templates. Django==2.0.4

However, I have a base class:

class TabularBase(nested_admin.NestedTabularInline):
    sortable_field_name = 'order'
    extra = 0

The problem seems to be with extra = 0. When extra = 1 (or greater), drag-and-drop works normally.

@globophobe can you check if the dj20-fix-tabular-inlines branch fixes your issue?

[globophobe]

There was no change. There were no errors in the javascript console.

I tried a few browsers, and cleared the cache. I had cloned the branch, and installed with "python setup.py develop"

pip freeze:

-e git+https://github.com/theatlantic/django-nested-admin.git@3a75b938ca0b802c180df822d2cdc5e58b321aa1#egg=django_nested_admin

I looked at 58b4c98

However, I'm not familiar with the code base.

Maybe, I'll look more on the weekend.

@globophobe did you ever get to the bottom of this?

[globophobe]

Sorry, not yet.
