I have two custom models(not inheriting from Page) that are specific to the admin in a Wagtail CMS website. I can get this working in regular Django, but in Wagtail I can't get the inline model fields to appear. I get a key error. The code...
On model.py:
from django.db import models
from wagtail.admin.panels import (
FieldPanel,
MultiFieldPanel,
FieldRowPanel,
InlinePanel,
)
from author.models import Author
class Book(models.Model):
author = models.ForeignKey(Author, on_delete=models.CASCADE)
date = models.DateField("Date released")
panels = [
MultiFieldPanel([
InlinePanel('book_review'),
], heading="Book reviews"),
]
class BookReview(models.Model):
book = models.ForeignKey(
Book, on_delete=models.CASCADE, related_name='book_review')
title = models.CharField(max_length=250)
content = models.TextField()
panels = [
FieldRowPanel([
FieldPanel('title'),
FieldPanel('content'),
])
]
and wagtail_hooks.py:
from wagtail.contrib.modeladmin.options import (
ModelAdmin,
modeladmin_register,
)
from .models import Book, BookReview
class BookAdmin(ModelAdmin):
model = Book
add_to_settings_menu = False
add_to_admin_menu = True
inlines = [BookReview] # only added this after key error, but it didn't help
modeladmin_register(BookAdmin)
How can I get the InlinePanel('book_review'), line to show up in the admin. It all works until I try add the inline model fields.
I looked around online and it was mentioning a third party Django modelcluster package. Is this still required? Those post were quite old(5 years or so). Or instead of using ForeignKey use ParentalKey, but that's only if inheriting from Page model.
