Question

我试图在模型上上传图像，然后在模板上显示。

Forms.py：

False

Models.py：

x = "a" if a else ("b" if b else ("c" if c else None))

views.py

class ClanakForma(forms.ModelForm):
    class Meta:
        model = Clanak
        fields = '__all__'

urls.py：

class Clanak(models.Model):
    naslov = models.CharField(null=False, blank=True, max_length=120)
    datumObjave = models.DateField(null=False, blank=False)
    autor = models.ForeignKey(Autor, on_delete=models.CASCADE, null=True)   
    videofile= models.FileField(upload_to='images/', null=True, verbose_name="")

    def __str__(self):
        return str(self.naslov) + ', ' + str(self.datumObjave) + ', ' + str(self.autor) + ', ' + str(self.videofile)

justadded.html：

def dodajClanak(request):
    if request.method == 'GET':
        forma = ClanakForma()
    elif request.method == 'POST':
        forma = ClanakForma(request.POST)
        if forma.is_valid():
            data = Clanak()
            data.naslov = forma.cleaned_data['naslov']
            data.datumObjave = forma.cleaned_data['datumObjave']
            data.autor = forma.cleaned_data['autor']
            data.videofile = forma.cleaned_data['videofile']
            #data.email = forma.cleaned_data['email']
            data.save()
            return redirect('readAllNew')
    return render(request, 'justadded.html', {'forma':forma})

def readAllNew(request):
    data = list(Clanak.objects.all())
    return render(request, 'readAllNew.html', {'data':data})

readAllNew.html

urlpatterns = [
    path('dodajClanak/',views.dodajClanak, name='dodajClanak'),
    path('readAllNew/',views.readAllNew, name='readAllNew'),
] + static(settings.MEDIA_URL, document_root= settings.MEDIA_ROOT)

我的问题是，当我转到http://127.0.0.1:8000/dodajClanak/并尝试上传出现错误的图像时：

用英语说：“您没有选择任何图像”。

当我进入链接http://127.0.0.1:8000/readAllNew/时，我看不到任何图像：

我可以通过管理站点上传它，但仍然看不到。

Answer 1

将表单更改为

<form action="{% url 'dodajClanak' %}" method="post" enctype=multipart/form-data>

并从中查看

 forma = ClanakForma(request.POST)
    if forma.is_valid():
        data = Clanak()
        data.naslov = forma.cleaned_data['naslov']
        data.datumObjave = forma.cleaned_data['datumObjave']
        data.autor = forma.cleaned_data['autor']
        data.videofile = forma.cleaned_data['videofile']
        #data.email = forma.cleaned_data['email']
        data.save()
        return redirect('readAllNew')

到

 forma = ClanakForma(request.POST,request.FILES)
    if forma.is_valid():

        forma.save()
        return redirect('readAllNew')

在使用ModelForm时，无需写所有这些行

尝试显示图片

    <td><img src='{{media_url}}{{ i.videofile.url }}'></td>

希望有帮助

无法上传并查看来自Django模型的图像
