python - Django 模型无法识别 MarkdownxFormField 字段

问题描述

我正在尝试为markdownx我的模型添加支持，这将允许从管理面板进行预览编辑。但是，一旦我将我的content字段从django 更改models.FileField为MarkdownXFromField()迁移时删除内容字段并忽略它，就好像它根本不是模型的一部分。

我完全遵循了这些文档，但它不起作用。

我也跑了collectstatic。

# models.py

from os.path import splitext
from uuid import uuid4
from django.db import models
from markdownx.fields import MarkdownxFormField

def hashImageFilename(instance, name):
    ext = splitext(name)[1]
    return "images/{}{}".format(uuid4(), ext)


class Article(models.Model):
    title = models.CharField(("title"), max_length=100)
    content = MarkdownxFormField()
    description = models.TextField(("description"), default='')
    uploadDate = models.DateTimeField(("uploadDate"), auto_now=True)
    lastModified = models.DateTimeField(("uploadDate"), auto_now=True)
    publicationDate = models.DateField("publicationDate")
    image = models.ImageField("image", upload_to=hashImageFilename)

    def __str__(self):
        return self.title

# urls.py

from django.contrib import admin
from django.urls import path, include
from django.conf.urls.static import static
from django.conf.urls import url
from django.conf import settings
from markdownx import urls as markdownx

urlpatterns = [
    path('admin/', admin.site.urls),
    path('api-auth/', include('rest_framework.urls')),
    path('api/articles/', include('articles.api.urls')),
    url(r'^markdownx/', include('markdownx.urls')),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

# admin.py

from django.contrib import admin

# Register your models here.
from markdownx.admin import MarkdownxModelAdmin
from .models import Article

admin.site.register(Article, MarkdownxModelAdmin)

# settings.py

INSTALLED_APPS = [
  #...
  'markdownx'
]

解决方案

您将表单字段与模型字段混淆了。您应该将模型重写为：MarkdownxFormField MarkdownxField

# models.py

from os.path import splitext
from uuid import uuid4
from django.db import models
from markdownx.models import MarkdownxField

def hashImageFilename(instance, name):
    ext = splitext(name)[1]
    return "images/{}{}".format(uuid4(), ext)


class Article(models.Model):
    title = models.CharField(("title"), max_length=100)
    content = MarkdownxFormField()
    description = models.TextField(("description"), default='')
    uploadDate = models.DateTimeField(("uploadDate"), auto_now=True)
    lastModified = models.DateTimeField(("uploadDate"), auto_now=True)
    publicationDate = models.DateField("publicationDate")
    image = models.ImageField("image", upload_to=hashImageFilename)

    def __str__(self):
        return self.title

MarkdownxFormField用于表单，因此它将使用特定的小部件等呈现。为了将内容存储在数据库中，您需要一个模型字段。
