ImageField url属性

Question

Django 3.0.6

models.py

class Image(models.Model):
    def image_tag(self):
        return mark_safe('<img src="{}" width="150" height="150" alt={} />'.format(self.image_300_webp_1.url, 
                                                                                   self.alt))

settings.py

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

测试：

>>> from image.models import Image
>>> i = Image.objects.first()
>>> i.image_tag()
'<img src="/media/home/michael/PycharmProjects/pcask/pcask/media/image/1/1_300_1x.webp" width="150" height="150" alt=asdf />'

问题：真实路径是/media/image/1/1_300_1x.webp。你能告诉我为什么是:媒体+图像的绝对路径吗？以及如何获得正确的路径？

Answer 1

向urls.py添加媒体url

from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    # ... the rest of your URLconf goes here ...
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
