I have updated the version of Django to 2.0 in an existing project, and I have followed all the steps necessary for the project to be compatible.

but I'm having problems in the administrator when creating or editing a model that uses attributes from this django-markdownx library

the error is caused in this file

File "/usr/local/lib/python3.6/site-packages/django/forms/widgets.py", line 114, in merge

...
        combined_list = list(list_1)
        last_insert_index = len(list_1)
        # Walk list_2 in reverse, inserting each element into combined_list if
        # it doesn't already exist.
        for path in reversed(list_2):

TypeError: 'set' object is not reversible
...

Local variables in frame

last_insert_index	0
combined_list	[]
list_2	                set(['markdownx/js/markdownx.js'])
list_1	                []

the variable list_2 is a list of set type

the simple solution that I think

is to convert that variable to a list
