问题是图像没有保存当我选择图像并上传所有代码工作正常但图像不保存 django

如何解决问题是图像没有保存当我选择图像并上传所有代码工作正常但图像不保存 django

问题是图像没有保存。当我选择一个图像并上传所有正常工作的代码但图像没有保存时​​。我逐行检查了所有代码我不明白是什么问题。我还看到媒体文件是否保存了任何图像，但图像未保存。

这是这个文件中的models.py 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)

解决方法

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，并且子文件夹的名称是否正确。

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)
