We are trying to migrate our Wagtail site data from DEV to Staging environments

I have a Wagtail Forms implementation that uses AbstractEmailForm. I have the two required templates (for the form, and for landing), and they render fine in the preview mode and in the admin preview panel, but when I actually try to submit on the form, it accepts the submission, and then fails to do anything else. The landing page is not shown, but I can see it returned as an HTML response to the form’s POST request.

I have a Django/Wagtail project that continuously updates Page instances with data retrieved via an external API. I somehow failed to implement a check to update and publish the internal instance only if the external data has changed. Therefore, Wagtail has created a lot of Revision instances. I fixed this erroneous behavior and purged old revisions using the Wagtail purge_revisions management command. That worked. But I still have a lot of PageLogEntry instances in my database.

I have a model with an InlinePanel. Can I change the label that is shown to be a field of the model underneath it, in this case the title of the Artist field, instead of just “Artist 1”?

I have a model that looks, simplified like this:

When I create content, I have its equivalent in the languages ​​added to my site in the DB.
So how to display only the last 3 articles of a single language on the home page using “ojects.all().order_by(‘-date’)[:3]”

Is it possible to create a readonly list of models with a custom queryset through a ModelViewSet in Wagtail admin?

My Wagtail app is configured to managing documents, and I want to include document links via a RichTextField of my page model. The output of the {{ page.body|richtext }} tag is missing a href attribute for document links:

Wagtail rewrite handlers allows to expand internal links adding custom HTML attributes, but will not allow to change the closing </a> tag.

I am wondering if it is possible to add a colorpicker feature to the Wagtail editor. I would like to select a portion of the text and change its color.
I’ve researched and found that there is a feature in the draftail documentation but it is still unclear for me how can I add it to the wagtail.
