Django：找不到页面，提出者：django.views.static.serve

Question

我正在尝试在 django 中显示 static 图像。 当我使用 django 管理门户的 select 图像时，它工作正常。 它正在显示图像。 But when I select image from my front-end page, I get: Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/media/destination-2.jpg Raised by: django.意见.static.server

这是我的代码：urls.py

from django.urls import path,include
from django.conf import settings
from django.conf.urls.static import static
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
from mainapp import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('mainapp.urls')),
]

admin.site.site_header = "Login to our web Portal"
admin.site.site_title = "This is Admin Portal"
admin.site.index_title = "Welcome to Amnet"

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

设置.py

STATICFILES_DIRS=[os.path.join(BASE_DIR,'static')
]

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

模型.py

from django.db import models

# Create your models here.
class Amnet(models.Model):
    imagee = models.FileField(default='bg_2.jpg')

视图.py

from django.shortcuts import render
from mainapp.models import Amnet
# Create your views here.
def index(request):
    if(request.method == "POST"):
        imagee= request.POST.get('imagee')
        am = Amnet(imagee=imagee)
        am.save()
        return render(request,'image-main.html')
    else:
        return render(request,'image-main.html')

html页面

<form action="" method="POST">
    {% csrf_token %} 
    <td><input type="file" name="imagee" id="file"></td>
    <td><img src="" id="profile-img-tag" width="200px" /></td>
</tr>

</table>
<input type="Submit" value="Submit" id="btn"><br>  
</form>

Answer 1

使用 enctype="multipart/form-data" 处理文件上传。 在 HTML 的表单标签中添加此属性
