Also removing the SortableInlineAdminMixin from WorkflowStepInline loads the admin view correctly in line https://github.com/django-cms/djangocms-moderation/blob/master/djangocms_moderation/admin.py#L1003

This comment might support your finding @vipulnarang95: https://django-admin-sortable2.readthedocs.io/en/latest/installation.html#upgrading-from-version-1

• Remove SortableInlineAdminMixin from WorkflowStepInline
• Ensure it is added to all admin classes using WorkflowStepInline, such as WorkflowAdmin

@joshyu Can you confirm @vipulnarang95's finding and that it solves the problem?

[joshyu]

@fsbraun , I removed both SortableAdminMixin and SortableInlineAdminMixin from inline admin and its parent class, It seems that the list rendered correctly, but I got an error while saving a new workflow.

We need to modify forms at https://github.com/django-cms/djangocms-moderation/blob/master/djangocms_moderation/forms.py#L26 It would work fine then

@vipulnarang95 , how to update this form? Can you share more detail?

@fsbraun,

I found that the error I mentioned was ever mentioned by Sergi of What.digital and he raised a PR for it.https://github.com/jrief/django-admin-sortable2/pull/371

[vipulnarang95]

Hi @fsbraun @joshyu I have removed the dependency of django admin sortable2 from djangocms moderation. We have tested this internally and it works fine as expected, just the sort feature in inline is removed which is not used.

[joshyu]

Hi @fsbraun / @vipulnarang95,

From my understanding, the sorting functionality might be in the requirements list, so I think it's not a best solution only to remove the dependencies of django-admin-sortable2.

Whether can we create a new branch without/adminsortable based on master branch, this temporary solution to remove the dependency of adminsortable2 will be put there.

How do you think?

[vipulnarang95]

From the authoring perspective this functionality of Sort is available just drag and drop feature is not available. If the problem is there in the dependent addon and for our release target we can get a dev release and fix it in later stage as this is not a blocker and the feature is also not used at all. @fsbraun please suggest the best possible way to deliver this.

[fsbraun]

I'd appreciate if we could keep the drag-and-drop sorting capability.

@jrief Can you give https://github.com/jrief/django-admin-sortable2/pull/371 a second look?

@vipulnarang95 @joshyu Is there a way of making a default_order_field not None in djangocms-moderation? And would this also fix the issue?

[vipulnarang95]

@fsbraun I checked and used this change in django admin sortable2 in my local and it still doesn't resolves the issue. The issue still exists

Also the getattr error josh mentioned was coming after removing the SortableAdmin and SortableAdminMixin class. I am debugging django admin sortable2 now and will share my findings.

Hi @fsbraun , This was not a issue for default_order_field, as there is a init method called _get_default_ordering(), this will return and set the default_order_field and default_order_direction 's value as 'name'. The problem was on the get_list_display() method they just replace the name column with _reorder_, which I believe should be append to the original list_display list.

And I believe we should add attribute enable_sorting to desired Admin and set its value as True if we want to enable sorting function or False if we don't need this.
