Question

我是Django的新手。我需要帮助。我想显示图像。在这里，我将图像路径保存到数据库，将图像保存到文件夹。请帮助我显示这些图像。

views.py ：

def uploadfile(request):
   print('inside upload logic')
   if request.method == 'POST':
      form = FileUploadForm(request.POST, request.FILES)
      if form.is_valid():
        # ImageUpload(request.FILES['File_Name'])  
         myfile = request.FILES['File_Name']

         fs = FileSystemStorage()
         filename = fs.save(myfile.name, myfile)
         uploaded_file_url = fs.url(filename)
         newdoc = FileUpload(File_Name=myfile.name, File_path=uploaded_file_url,  Description=request.POST['Description'])
         newdoc.save()
         #return HttpResponse("File uploaded successfuly")  
         return render(request, 'Login/fileupload.html')   
   else:
      form = FileUploadForm()
      return render(request, 'Login/fileupload.html', {
      'form': form
   }) 

def dataretrive(request):
   newdoc=FileUpload.objects.all()
   return render(request,'Login/displayimage.html',{'FileUpload':FileUpload})

我的模型：

 class FileUpload(models.Model):
    File_Name = models.CharField(max_length=255, blank=True)
    File_path = models.FileField(upload_to='')
    Description = models.CharField(max_length=255, blank=True)
    Upload_Date = models.DateTimeField(auto_now_add=True)

Check this

将此添加到您的模型中：

 class FileUpload(models.Model):
    File_Name = models.CharField(max_length=255, blank=True)
    File_path = models.FileField(upload_to='')
    Description = models.CharField(max_length=255, blank=True)
    Image = models.ImageField(upload_to=upload_location)
    Upload_Date = models.DateTimeField(auto_now_add=True)

def upload_location(instance, filename):
    filebase, extension = filename.split(".")
    return "%s/%s" % (instance.id, filename)

在您的settings.py文件中，请确保设置MEDIA_URL和MEDIA_ROOT：

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

要访问模板中的MEDIA_URL，必须将django.template.context_processors.media添加到TEMPLATES配置中的context_processeors中。

将此添加到您的模板：

{% if instance.image %}
  <img src="{{ instance.image.url }}" class='img-responsive' />
{% endif %}

将路径保存到数据库并将图像保存到Django中的文件夹时如何查看图像？
