CreateView - 尝试保存图像上载时获取TypeError

标签: python django forms django-class-based-views

我试图围绕图像和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使用自定义表单覆盖它,以便成功上传/保存和映像?

我无法弄清楚为什么我会这样做:

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

整个事情都是准系统,没有库存。

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']

新闻/模板/消息/ post_form.py

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

任何人都可以帮助我理解吗?

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'

答案 0 :(得分:0)

您已将MEDIA_ROOT设置为元组,但它应该是一个字符串。

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