python – 提交后的django clear form字段

2019-08-30 14:59:21 阅读：120 来源： 互联网

我有一个上传表单,在每个表单提交后,我想清除发布的数据,实际上表单是持有提交的数据.我知道,如果我将我的页面重定向到其他页面,这个问题可以解决,但我不知道我想重定向我的页面,因为在提交数据后,该页面中会显示成功消息.那么如何在不重定向页面的情况下清除表单？

这是我的views.py文件

def UserImageUpload(request):


    if request.method == 'POST':
            form = DocumentForm(request.POST,request.FILES)
            if form.is_valid():
                    messages.add_message(request, messages.SUCCESS, 'Your Image upload is waiting for Admin approval')


                    newdoc = Photo(photo = request.FILES['photo'],watermarked_image=request.FILES['photo'],user = request.user,name = request.POST['name'],description = request.POST['description'],keyword = request.POST['Image_Keyword'],uploaded_time=datetime.datetime.now(),Certified=request.POST['Certification'])

                    newdoc.save()
            else:
                    messages.add_message(request, messages.ERROR, 'Please Complete All Fields To Submit Your Image')



    else:
            form = DocumentForm()

    uploaded_image = Photo.objects.all()

    return render_to_response('myprofile/user_image_upload.html',{'uploaded_image':uploaded_image,'form':form},context_instance = RequestContext(request))

这是我的forms.py文件

from django import forms

class DocumentForm(forms.Form):
    photo = forms.ImageField( 
            label='Select A file',)
    name = forms.CharField(label='Image Name',max_length=50,widget=forms.TextInput(attrs={'class' : 'form-control',}))
    Certification = forms.BooleanField(label='I certify that this is my original work and I am atlest 18 years of age')
    description = forms.CharField(label='Image Description',max_length=500,widget=forms.TextInput(attrs={'class' : 'form-control',}))
    Image_Keyword = forms.CharField(label='Keywords',widget=forms.TextInput(attrs={'class' : 'form-control',}))

解决方法:

我已经解决了它.在views.py中,保存表单后只需指定空表单,就像那样

def UserImageUpload(request):

    if request.method == 'POST':
             form = DocumentForm(request.POST,request.FILES)
             if form.is_valid():
                     messages.add_message(request, messages.SUCCESS, 'Your Image upload is waiting for Admin approval')
                     newdoc = Photo(photo = request.FILES['photo'],watermarked_image=request.FILES['photo'],user = request.user,name = request.POST['name'],description = request.POST['description'],keyword = request.POST['Image_Keyword'],uploaded_time=datetime.datetime.now(),Certified=request.POST['Certification'])
                     newdoc.save()
                #Assign the empty form,it will empty the form after a successful form submission
                     form=DocumentForm()  
             else:
                   messages.add_message(request, messages.ERROR, 'Please Complete All Fields To Submit Your Image')
     else:
             form = DocumentForm()
     uploaded_image = Photo.objects.all()
     return render_to_response('myprofile/user_image_upload.html',{'uploaded_image':uploaded_image,'form':form},context_instance = RequestContext(request))

无需重定向您的页面.
