如何使用Django表单存储图像？

Question

我是Django的新手。我已经被困了一段时间了。我相信一切都正确配置了。但是，当创建我的对象时，它不会创建媒体目录或存储文件/图像。我已经完成了设置文件，URL，视图，模型，形成所有内容。

这是相关文件：

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

// models.py
class Trip(models.Model):
    city = models.CharField(max_length= 255)
    country = models.CharField(max_length= 255)
    description = models.CharField(max_length= 255)
    creator = models.ForeignKey(User, related_name = 'trips_uploaded',on_delete= CASCADE, null=True)
    favoriter = models.ManyToManyField(User, related_name= 'fav_trips')
    photo = models.ImageField(null=True, blank =True, upload_to='trips/')

// urls.py ( there were 2 ways to write media according to tutorial)
from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('travelsiteapp.urls'))
]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) 

# urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) 

// views.py (lastly)
def tripAdd(request):
    form = TripForm()
    if request.method == 'POST':
        form = TripForm(request.POST, request.FILES)
        if form.is_valid():
            form.photo = form.cleaned_data["photo"]
            form.save()

    context = { 'form': form}
    return render(request, 'tripAdd.html', context)

// html/ form

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

// forms.py 

from django import forms
from django.forms import ModelForm
from .models import Trip
from django import forms

class TripForm(ModelForm):
    class Meta:
        model = Trip
        fields = ['city', 'country', 'description', 'photo']


// I have hit all the steps not sure whats wrong? & and installed pip pillow

哪个URL服务tripadd（）视图？如果它是/createTrip，如您的表单中，请在这样的操作中添加一个trailling slash：/createTrip/。当您发布到URL时，Django默认情况下会拖延斜线。您可以自定义如果您愿意的话。另外，不要忘记声明此URL（因为它不是您提供的示例）。
