Hi, wagtailmenus is still not compatible with Wagtail 3.0 unfortunately.

[basitiyidir]

I want to start a new project with Wagtail 3. When will this bug be fixed.

how can i fix it temporarily

Thank you.

[janbaykara]

Can someone who's familiar with Wagtail's panel system comment here with roughly what the problem seems to be? I poked around the code for 5 minutes but it didn't occur. Happy to put up a fix but I can't invest the debugging time right now.

• Going to guess that we need to run updatemodulepaths on this repo, at the least.
• Seems there have been quite a few changes to the panels / edit handlers API surface that we'll need to factor in.

I poked around with the code https://github.com/jazzband/wagtailmenus/blob/8be2790c01688dd3c9ef7298bdebe94575c0a76a/wagtailmenus/views.py#L50-L60 and I noticed that removing this condition stopped the error from showing.

        if hasattr(edit_handler, 'bind_to'):
            # For Wagtail>=2.5
            return edit_handler.bind_to(model=self.model)

Main menu was working fine but a temporary fix for wagtail 3.0.

@amajai nice sleuthing. Do you want to submit this as a PR to close this issue? While we're waiting for the maintainers to merge it in, we can point our package managers to your fork.

I'm waiting for someone to PR.

[amajai]

Alright, I'll make a PR.

[janbaykara]

Some of my end users are blocked by this issue, so I've gone ahead and posted a PR based on @amajai's suggestions here: https://github.com/jazzband/wagtailmenus/pull/422 It seems to work just enough for my purposes, for now, but it'd be good iron out any creases.

Happy to take the PR down if you want to post your PR @amajai.

[amajai]

@janbaykara I was actually going to post PR later today. Had to go over the code and documentation to make proper changes during my free time. Sorry that it took long.

[amajai]

Temporary fix to wagtail 3.0 for now until wagtailmenus gets updated: pip install -e git+https://github.com/amajai/wagtailmenus.git@resolve-wagtailmenus-compatibility-issue-wagtail-3.0#egg=wagtail

@basitiyidir Try updating your python version to 3.7 or above.
