Livepreview is removing all the script tags in the generated HTML. (https://github.com/KalobTaulien/wagtail-livepreview/blob/master/livepreview/static/livepreview/js/livepreview_fe.js#L4)

Javascript could be used to position elements, to apply CSS styles, to add lazy loading, etc. Removing all the scripts from the page could greatly affect the view of the page (even for simple sites that don't use any JS framework).

It would be great to stop removing all the script tags in the HTML, as this can affect the preview of the pages.

Maybe the stripScripts function should only remove the scripts inside the div with the class js-livepreview-script?

Wagtail 2.10 will have lots of template changes and might not be compatible with this package.

I'd LOVE if someone could test this out with 2.10 and report back (may need to work on #15 first).

Nice package, @KalobTaulien !

Opening this "issue" so as to not forget:

https://github.com/torchbox/wagtail-headless-preview has live preview capabilities. I did not get a chance to test the two together, but think there is scope for them to work in tandem.

Will try to get some time to investigate. Will report back with the findings and any tweaks we may need to make.

In wagtail 2.9 and later, request.site will not be available (or deprecated).

Creating a translated page using wagtailtrans is always showing the language as the user wagtail language (in this case 'en') instead of the real page locale in the livepreview window

Even when we set LIVEPREVIEW_USE_FILE_RENDERING=False application tries to make a folder to store rendered page. It could be easily fixed by changing this code

in views.py line 123

        file_name = self.get_live_preview_file_name(page_id, request.user.id)
        use_file_rendering = getattr(settings, "LIVEPREVIEW_USE_FILE_RENDERING", True)
        if use_file_rendering and os.path.isfile(file_name):
            with open(file_name, 'r') as file:
                page_content = file.read()
                return HttpResponse(page_content)

to

        use_file_rendering = getattr(settings, "LIVEPREVIEW_USE_FILE_RENDERING", True)
        if use_file_rendering:
            file_name = self.get_live_preview_file_name(page_id, request.user.id)
            if os.path.isfile(file_name):
                with open(file_name, 'r') as file:
                    page_content = file.read()
                    return HttpResponse(page_content)

Hey.

This app is a nice idea and i'd like to use it in my project (and maybe contribute in a future with some improvements) but currently i have a problem with page in "live preview" mode.

The problem is than in template {{ request.site }} returns None when page is rendered by live_preview endpoint. I have no idea where to find a problem.

Wagtail's vanilla "preview" endpoint works well. Do you have any clues?

Hi Kalob, i have a bug with the live preview the panel shows up but its empty with the below message:
The message says the connection is blocked.

There is a Toggle live preview button that shows and hides the livepreview window, but when you load a page it always shows the window by default. It would be great to have an option in settings HIDE_LIVEPREVIEW to hide the window by default when someone is editing a page.

Also, sometimes you want to show livepreview in some environments (Staging and Dev) and hide it in others (Production). It would be very useful to have another option in settings DISABLE_LIVEPREVIEW to disable livepreview globally.

File "/Users/andy/projects/po-website/.venv/lib/python3.8/site-packages/livepreview/wagtail_hooks.py", line 9, in

from django.contrib.staticfiles.templatetags.staticfiles import static

ModuleNotFoundError: No module named 'django.contrib.staticfiles.templatetags'

When i click "live preview" button it opens a new window with page preview. It refreshes in "real time" when i modify my page form so this works OK - but it stops working when i "hide" the iframe on right side of page form. If i show it again the separate full windows refreshes again.

// EDIT
OK i see that when i turn off iframe form does not make POST to live_preview thats why this separate full windows does not see changes when refreshes body.

Do you have any idea why it happens and how to fix it?
