AttributeError at /admin/documents/document/

[goose-ws]

When I pull up my /admin/documents/document/ I get the following error message:

Request Method: GET  
http://192.168.1.100:7412/admin/documents/document/  
1.11.13  
AttributeError

Here is the traceback it provides:
http://dpaste.com/3ABY9YA.txt

I checked out issue #414 and #415 -- However, I don't believe it's a dates issue, as I originally had no documents at all and was getting the error. After processing in 3 documents, I see the dates as:

goose@eddard:~/bin/paperless/src$ echo "SELECT created, modified, added FROM  documents_document ORDER BY added" | ./manage.py dbshell  
2018-01-08 00:00:00|2018-10-03 15:56:34.695460|2018-10-03 15:56:34.695273

Would thoroughly appreciate any help :)

Exception Type: AttributeError at /admin/documents/document/
Exception Value: 'DocumentAdmin' object has no attribute 'get_changelist_instance'

This happened after upgrading to the current version with git pull and ./manage.py migrate. The webserver starts without any problems and all links apart from Documents work fine.

I do not have any invalid dates in the database and before the update it worked just fine.

The line in question references commit fb6f2e0

If I uncomment the following lines (215-217), the server is working normally:

if request.method == "GET":
       cl = self.get_changelist_instance(request)
       self.document_queue = [doc.id for doc in cl.queryset]

It looks like you're both running the wrong version of Django. Paperless upgraded to 2.x some time ago. Remember that part of the upgrade process is to update project dependencies with pipenv or pip:

pipenv

cd /path/to/paperless/root
pipenv install

pip

pip install -r /path/to/paperless/root/requirements.txt

If you do that, restart the webserver, and there's still a problem, let me know, and if not, please close this issue.

[danielquinn]

Update: I just realised that the migration docs didn't actually include a line about updating Python depdendencies, so yeah, this was my bad, sorry.

Anyway, I've added a note for them now, so if you remember to do the update, I'm reasonably sure you should be ok.

Ah perfect, thank you very much. That did indeed fix the issue
