Bedrock: Upgrade Django to latest 1.11

[pmac]

1.11 is the next LTS release and we should move to it. This covers upgrading Django and all other libs required to be updated to support it.

Hi

I am interested in this issue. Please tell me how to proceed?

[pmac]

This is going to be a lot of work I'm afraid. If you're an experienced Django developer then feel free to give it a shot, but I expect it to be a rather large project as some 3rd party library updates will potentially require major changes.

Hi @pmac
What's the progress of this issue?

[delterr]

I think we should upgrade to 2.0, it makes life a lot easier with its new syntax

[NdagiStanley]

True. It's best we upgrade to version 2.0

[NdagiStanley]

@pmac could we create a branch for this upgrade to Django 2 so that we can collaboratively make this upgrade?

I'll shift the base of the PR I have raised to that branch.

The PR is broken. It's still WIP. I thought I could set the ball rolling.

Cheers.

I would advise against Django 2 for now, especially since it drops support for Python 3 (this repository is still using Python 2). Everything needs to be made Python 3-compatible first, which is, itself, a large challenge (e.g. some packages need to be updated (e.g. some of the current packages are Python 2-only, but have later versions that support Python 3), imports fixed (explicit relative imports, urllib/urlparse to urllib.request/urllib.parse), cStringIO.StringIO/StringIO.StringIO to io.BytesIO/io.StringIO (as appropriate), etc.

Thanks for the heads up

We do want to get to Django 2 eventually, but for now the best path forward is 1.11. @StephenOrJames is right that it will be quite a lot of work to get to Python 3. I think it's going to be a good bit of work to get to 1.11 even.

As a reminder, Django 1.8 LTS has ended a few days ago (1 April 2018) according to https://www.djangoproject.com/download/#supported-versions
Although this project isn't even on latest 1.8 version

If I understand correctly the plan is:

• Django 1.11 with Python 2.7
• Django 1.11 with Python 3+
• Django 2+

[NdagiStanley]

I guess @BojanKogoj. @pmac, right?

[pmac]

Looks like you are right. We'll be accellerating the move to 1.11 this quarter. Thanks for the reminder.

[NdagiStanley]

@pmac I'm curious. How did this go?

[pmac]

Still not done :( We're going to do kitsune first and then bedrock.

[NdagiStanley]

On this issue? https://github.com/mozilla/kitsune/issues/3177

[pmac]

We have finally completed this! It went live earlier this week. It was done in #7135
