問題描述

為什麼 RichText 不能在 wagtail 管理員中為帖子工作？這是發生的事情的類型：

嘗試 post.content|richtext

Trying post.content|richtext

Wagtail 在現有 Django 站點上實現。我已經包含了最有可能包含錯誤的代碼部分。如果您還想要其他任何東西，請隨時提出要求。代碼如下：models.py

from django.conf import settings
from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
from django.urls import reverse
from django.utils.text import slugify

from wagtail.core.models import Page
from wagtail.core.fields import RichTextField
from wagtail.admin.edit_handlers import FieldPanel

class Subject(models.Model):
    subject = models.CharField(max_length=200)
    subject_slug = models.SlugField(editable=True, max_length=200, null=False, unique=True)
    def get_absolute_url(self):
        kwargs = {
            'slug': self.slug
        }
        return reverse('subject', kwargs=kwargs)
    def save(self, *args, **kwargs):
        value = self.subject
        self.slug = slugify(value, allow_unicode=True)
        super().save(*args, **kwargs)

    panels = [
        FieldPanel('subject'),
        FieldPanel('subject_slug')
    ]

    class Meta:
        # Gives the proper plural name for class called subject
        verbose_name_plural = "Subjects"

    def __str__(self):
        return self.subject

class Post(models.Model):
    author = models.ForeignKey(User, default=1, on_delete=models.SET_DEFAULT, related_name='blog_posts')
    date_added = models.DateTimeField(auto_now_add=True)
    subject = models.ForeignKey(Subject, verbose_name='Subject', default=1, on_delete=models.SET_DEFAULT)   
    title = models.CharField(max_length=200, unique=True)
    slug = models.SlugField(editable=True, max_length=200, null=False, unique=True)
    content = RichTextField()
    def get_absolute_url(self):
        kwargs = {
            'slug': self.slug
        }
        return reverse('post_detail', kwargs=kwargs)
    def save(self, *args, **kwargs):
        value = self.title
        self.slug = slugify(value, allow_unicode=True)
        super().save(*args, **kwargs)

    content_panels = Page.content_panels + [
        FieldPanel('author'),
        FieldPanel('subject'),
        FieldPanel('title'),
        FieldPanel('slug'),
        FieldPanel('content')
    ]

    class Meta:
        ordering = ['‑date_added']

    def __str__(self):
        return self.title

class Comment(models.Model):
    post = models.ForeignKey(Post, default=1, on_delete=models.SET_DEFAULT, related_name='comments')
    name = models.CharField(max_length=80)
    email = models.EmailField()
    body = models.TextField()
    made_on = models.DateTimeField(auto_now_add=True)
    active = models.BooleanField(default=False)

    class Meta:
        ordering = ['made_on']

    def __str__(self):
        return 'Comment {} by {}'.format(self.body, self.name)

    prepopulated_fields = {'slug': ['title'],}

modeladmin_register(SubjectAdmin)
modeladmin_register(PostAdmin)

機器需要更多細節。除了我不想在我的帖子中說的以外，我不確定我還能說什麼：

Heading H2

Bold 而不是粗體

H3 粗體和斜體很有趣

參考解法

方法 1:

Thanks gasman, the way I fixed it was I implemented post.content|richtext and loaded wagtailcore_tags in templates and it works!
