CreateView - 尝试保存图像上传时出现 TypeError

Question

我正在努力思考图像和 Form handling with class-based views。所以我正在玩这个简单的模型。使用 CreateView 时，我是否必须使用 form_class 用自定义表单覆盖它才能成功 upload/save 和图像？

我不明白为什么我会收到这个：

Exception Type:     TypeError
Exception Value:    expected str, bytes or os.PathLike object, not tuple

整件都是准系统，缺货。

models.py

class Post(models.Model):
    headline = models.CharField(max_length=80, blank=True, null=True)
    cover_image = models.ImageField('hero image', upload_to='images/', blank=True, null=True)
    slug = models.SlugField(max_length=80, blank=True, null=True, unique=True)

    def get_absolute_url(self):
        return reverse('details', args=[str(self.slug)])

views.py

from django.contrib.auth.mixins import LoginRequiredMixin
from django.views.generic import CreateView

class PostCreateView(LoginRequiredMixin, CreateView):
    model = Post
    fields = ['headline', 'cover_image', 'slug']

news/templates/news/post_form.py

<form enctype="multipart/form-data" method="post" action="">
    {% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Save"/>
  </form>

谁能帮我理解一下？

根据要求

# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/2.0/howto/static-files/

STATIC_URL = '/static/'

STATICFILES_DIRS = (os.path.join(BASE_DIR, 'static'),)

MEDIA_ROOT = (os.path.join(BASE_DIR, 'media'),)
MEDIA_URL = '/media/'

LOGIN_REDIRECT_URL = 'home'

Answer 1

您已将 MEDIA_ROOT 设置为一个元组，但它应该是一个字符串。

MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
