个人资料图片未显示

我可以上传一张个人资料图片并将其放入数据库。我的views.py中有一个“print(profile.profile_picture)”,当我保存时,它将正确打印控制台中的当前配置文件图片。由于某种原因,个人资料图片将不会显示,但我的个人资料.html中的“{%if profile.profile_picture%}”甚至没有拾取任何内容。 [ ]

意见。PY=

@login_required
def profile(request):
    profile, created = Profile.objects.get_or_create(user=request.user)
    print(profile.profile_picture)
    if request.method == 'POST':
        form = ProfileForm(request.POST, request.FILES, instance=profile)
        if form.is_valid():
            form.instance.user = request.user
            form.save()
            return redirect('base:profile')  # Redirect to the home page after form submission
    else:
        form = ProfileForm(instance=profile)
    
    return render(request, 'profile.html', {'form': form})

轮廓。HTML=

    <div class="ProfilePage">
        <form method="POST" enctype="multipart/form-data" class="profile-form">
            {% csrf_token %}
            
            <div class="form-group">
                <label for="id_username">Username:</label>
                <input type="text" id="id_username" value="{{ request.user.username }}" readonly>
            </div>

            <div class="form-group">
                <label for="id_bio">Bio:</label>
                <textarea id="id_bio" name="bio" rows="4" cols="50" required>{{ form.bio.value }} </textarea>
            </div>

            <div class="form-group">

            </div>
            
            {% if profile.profile_picture %}
                <div class="form-group">
                    <label>Profile Picture Preview:</label><br>
                    <img src="{{ profile.profile_picture.url }}" alt="Profile Picture" style="max-width:     500px;">
                </div>
            {% endif %}
    
            <button type="submit" class="btn-submit">Save</button>
            
            
        </form>
    </div>                                                                                                      

形式。PY=

     from django import forms
     from .models import Profile

     class ProfileForm(forms.ModelForm):
       class Meta:
         model = Profile
         fields = ['bio', 'profile_picture'] 

url。PY=

    from django.contrib import admin
    from django.urls import path, include
    from django.conf import settings
    from django.conf.urls.static import static
    from base import views  # Import views from the base app

    urlpatterns = [
    path('admin/', admin.site.urls),
    path("", include(("base.urls", "base"), namespace="base")),  # Include     
 app-level URLs with a namespace
    path('profile/settings/', views.profile_settings, name='profile_settings'),
    path('profile/<str:username>/', views.public_profile, name='public_profile'),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

模型。PY=

    from django.db import models
    from django.contrib.auth.models import User
    from django.contrib.auth import get_user_model
    import uuid
      from datetime import datetime

    User = get_user_model()

    class Profile(models.Model):
          user = models.OneToOneField(User, on_delete=models.CASCADE)
          bio = models.TextField(blank=True)
          profile_picture = models.ImageField(upload_to='profile_pics',       
 blank=True)

     class Post(models.Model):
          id = models.UUIDField(primary_key=True, default=uuid.uuid4)

          created_at = models.DateTimeField(default=datetime.now)
          no_of_likes = models.IntegerField(default=0)

          def __str__(self):  
              return self.user

我可以提供更多信息,我有点困惑为什么这不起作用。
