Question

如何将模板标签从models.TextField呈现为html。在我的django管理员中：

我打算用一些所见即所得的编辑器扩展内容。

在wiews.py中，我定义了如何将其呈现为html格式：

from django.shortcuts import render
from .models import Email

def EmailData(request, slug):

   email = Email.objects.get(slug=slug)

   return render(request, email.template.path,{
       "email": email
   })

HTML：

{% extends "baseEmail.html" %}
{% block emailContent %}

        <h1>{{ email.email }}</h1>
        <h2>{{ email.subject }}</h2>

        <h2>{{ email.content|safe }}</h2>

        <h2>{{ email.created }}</h2>
        <h2>{{ email.sendToAdmin }}</h2>
        <h2>{{ email.template.path }}</h2>
{% endblock %}

h1标签正确显示，但变量未正确显示。如何从文本字段呈现变量集？

这是结果：

    while Email.objects.filter(slug=unique_slug).exists():
        unique_slug = '{}-{}'.format(slug, num)
        num += 1
    return unique_slug

def save(self, *args, **kwargs):

    self.slug = self._get_unique_slug()

    super().save()
