问题是图像没有保存。当我 select 图片并上传所有代码正常工作但图片不保存 django

Question

问题是图像没有保存。当我 select 一张图片并上传所有正常工作的代码但图片没有保存时。我逐行检查了所有代码我不明白是什么问题。我也看到媒体文件任何图像是否保存，但图像没有保存。

这是 models.py 在这个文件中我使用图像字段 models.py

class Answer (models.Model):
  question=models.ForeignKey(Question,on_delete=models.CASCADE)
  user=models.ForeignKey(User,on_delete=models.CASCADE, null=True)
  img=models.ImageField(null=True,blank=True,upload_to='Answer_Img')
  detail=RichTextUploadingField()
  add_time=models.DateTimeField(auto_now_add=True)


  def __str__(self):
    return self.detail

forms.py

 class AnswerForm(ModelForm):
    class Meta:
            model=Answer
            fields=('detail','img')
            labels={'img':'Upload Image'}

views.py

def answer(request,pk,slug):
    try:
        trend=Question.objects.get(pk=pk,slug=slug)
    except:
        raise Http404("Post Does Not Exist")
    tags=trend.tags.split(',')  
    ans=Answer.objects.filter(question=trend)
    answerform=AnswerForm
    if request.method=='POST':
        answerData=AnswerForm(request.POST)
        if answerData.is_valid():
            answer=answerData.save(commit=False)
            answer.question=trend
            answer.user=request.user
            answer.save()
            p=messages.success(request,'Answer has been submitted.')
        return HttpResponseRedirect(trend.slug)
    
    return render(request,"ask/answer.html" ,{
        'trends':trend,
        'tags':tags,
        'answer':ans,
        'form':answerform,
        
        })

answer.html

{% if user.is_authenticated %}
    <div class="container">
      <div class="py-5 text-center bg-secondary text-white">
      <h1 class="mb-3">Upload Image</h1>
      <form action="" method="post" enctype="multipart/form-data">
        {% csrf_token %}
        {{form}} 
        <input type="submit" class="btn btn-danger" value="Upload">
      </form>
      </div>
      {% else %}
    <h3><P>Sign In/Sign Up before posting answers</P></h3>
    <h4><li><a href="{% url 'account_login' %}" class=" text-left text-info">Sign In</a></li><h4>
    <h4> <li><a href="{% url 'account_signup' %}" class=" text-left text-info">Sign Up</a></li><h4>

{% endif %}

settings.py

    STATIC_URL = '/static/'

    MEDIA_URL = '/media/'

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

urls.py

urlpatterns = [
   # my url patterns here
]
if settings.DEBUG:
   urlpatterns += static(settings.STATIC_URL, document_root = settings.STATIC_ROOT)
   urlpatterns += static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT)

使用request.files获取img。请检查媒体文件夹是否在您的基本目录中以及子文件夹是否命名正确。

if request.method == "POST":
    
    answer_form = Answer_form(data=request.POST)

    if(answer_form.is_valid()):
        ans = answer_form.save(commit=False)
        #ans.user = user

                
        if 'img' in request.FILES:
            ans.img = request.FILES['img']
        
        ans.save()
    
    else:
        print(answer_form.errors)
