IndexError about mezzanine2jekyll

[sjkingo]

Hi Ross Will definitely look into this for you. Django has changed their management commands significantly in recent versions, so perhaps that's where the problem lies. Do you know the specific version or commit hash of Mezzanine that you're using?

[rosslaird]

Thanks in advance for the help. I'm using Mezzanine 4.1.0.

Could you paste the output of pip freeze inside the virtualenv?

I can't seem to reproduce, but I believe it may have something to do with the change in arguments handling, given the traceback.

Can you paste the exact command you're trying to run?

[rosslaird]

python manage.py mezzanine2jekyll ~/jekyll

[sjkingo]

I've just pushed a fix to pypi as version 1.0.1 - could you update and see if the problem is resolved?

[rosslaird]

Thanks so much for helping me out with this. It's probably not the kind of thing you really want to be working on...

I've upgraded, and here is the result:

... File "/home/rosslaird/website/website/urls.py", line 55, in <module> url("^$", "mezzanine.pages.views.page", {"slug": "/"}, name="home"), File "/home/rosslaird/.virtualenvs/rosslaird/local/lib/python2.7/site-packages/django/conf/urls/__init__.py", line 85, in url TypeError('view must be a callable or a list/tuple in the case of include().') TypeError: view must be a callable or a list/tuple in the case of include().

I created a new instance of Mezzanine locally, imported the existing database into it, and ran the command. Here's what I get (slightly different):

...File "/home/ross/.virtualenvs/rosslaird/lib/python3.6/site-packages/mezzanine2jekyll/management/commands/mezzanine2jekyll.py", line 26, in handle content = post.content.encode('utf-8').replace('\r', '') TypeError: a bytes-like object is required, not 'str'

This error I recognize. It's a python 2 --> 3 version issue. Maybe it helps you to track down the root cause.
Also, in this new instance, the command actually runs for a bit before crashing. So, I think it is getting farther.

[rosslaird]

So, a development: the initial error ("view musty be a callable or a list...") does not happen on the local setup. It does happen on the remote setup, with the same database. I can reproduce it on the remote site with this command:

python manage.py dumpdata page --indent 2 > ~/pages.yaml

That command runs perfectly on the local setup. So, this means I can actually get the posts/pages into yaml locally, then use a utility such as html2text to strip the html and end up with pages/posts that can be brought into Jekyll. I can live with this workflow. So, no need to try to figure this out (unless you are driven to do it).

[rosslaird]

I realized I was running Python 3 in my local virtualenv, so I created another virtualenv with Python 2.7, and the script ran perfectly. Thanks so much for putting this out there.

Great to hear you've sorted it out. I should definitely add some tests and CI - this sort of version mismatch would be easily resolved then.

Be aware that some bits of Mezzanine/filebrowser don't yet play 100% well with Django 1.11 or Python 3.5+, in case you're getting some weird errors.
