Unable to create root folder if the name is duplicated from a child folder

[bachvtuan]

Sample:
I have "RootFolder" and its child folder "SubFolder"
I can't create another root folder with name "SubFolder"

@bachvtuan I cannot reproduce this.

Which version are you using?
Do you have any filer-specific settings?

[bachvtuan]

Version: django-filer-3.3.1
@fsbraun I found out FILER_ENABLE_PERMISSIONS=True
Not sure that is a feature or a bug.

All right, setting FILER_ENABLE_PERMISSIONS = True seems to cause the issue. I'll have a look.

The culprit might be here. I need to find out why this is happening:

django-filer/filer/admin/folderadmin.py

Lines 89 to 107 in 7aa9b13

	folder_form = super().get_form(

	folders_with_same_name = self.get_queryset(request).filter(
	parent=form_obj.instance.parent,
	name=cleaned_data['name'])
