Question

 # models.py

from django.db import models
from . import constants

class Photos(models.Model):
    band_member = models.ForeignKey(BandMember,on_delete=models.CASCADE)
    photo = models.ImageField(upload_to='media/')
    photo_description = models.TextField(max_length=400)

class Photos(models.Model):
    band_member = models.ForeignKey(BandMember,on_delete=models.CASCADE)
    photo = models.ImageField(upload_to='media/')
    photo_description = models.TextField(max_length=400)

    @property
    def photo_url(self):
        if self.photo and hasattr(self.photo, 'url'):
            return self.photo.url

#  views.py

def member_photos(request,member_id):
    current_member = BandMember.objects.get(pk=member_id)
    photos = current_member.photos_set.all()
    context = {
        'all_photos': photos,
        'current_member': current_member,
              }
    return render(request,'band_members/member_photos.html', context)

html文件：

{% if all_photos %}
   {% for foto in all_photos %}
        <img class"" src="{{ foto.photo_url }}"  
        alt = {{foto.photo_url }}">
        <h5>{{ foto.photo_description }}</h5>
   {% endfor %}

尽管未显示图像，但alt显示了文件的正确路径

我在做什么错？我要达到的目的是，当用户单击页面上的“ SHOW PHOTOS”按钮时，该页面包含有关特定乐队成员的信息

（此处为site / band_member / member_id），将加载另一个页面（site / band_member / member_id / photos），显示当前成员的所有照片。

DJANGO的新手！！！谢谢！对不起，我的英语不好：)

Answer 1

循环中的html不正确。尝试像这样修复它。

 <img src="{{ foto.photo_url }}" alt ="{{foto.photo_url }}">
 <h5>{{ foto.photo_description }}</h5>

Django ImageField无法在<img/>标签HTML呈现
