Question

在开发环境中我可以加载表单并更新任何文本字段，django会自动处理静态图像。

在webservice处理的生产静态图像中，它在表单更新视图中加载图像，但它再次要求在每次更新中选择图像。它无法识别现有的图像，我知道我必须在视图中处理它，但不确定它是如何完成的。请帮助解决它。

models.py

 class Shop(models.Model):

name        = models.CharField('Shop Name', max_length=200)
    address     = models.CharField('Door numb, Building',        max_length=100    )
    street      = models.CharField('Street Name',        max_length=100                        )
    sublocal    = models.CharField('Area (if any)',        max_length=100,blank=True,null=True )
    location    = models.CharField('Locality',        max_length=100                        )
    //
    landmark    = models.CharField('Landmark/Complex/Mall (If any, )', max_length=500, null=True, blank=True)

    phone        = models.CharField('Phone Number', max_length=100)
    //
    pfimage        =    models.ImageField('Profile Photo', upload_to='shop/%Y',)

    pfimage_thumb        =   ImageSpecField(source='pfimage',
                                            processors=[Transpose(),ResizeToFill(200, 150), Adjust(contrast=1.2, sharpness=1.1)],
                                            format='JPEG',
                                        options={'quality': 95})

    uid         =models.CharField('Shop URL (optional) - shopmapy.com/< pincode>/', max_length=100, blank=True)

views.py

@csrf_protect
@login_required
def shopreregister(request, qs):
    vshop = Shop.objects.filter(user__username=request.user) 
    shop =    get_object_or_404(vshop, pk=qs)
    print shop
    form = ShopForm(data = request.POST or None, instance=shop)
    form.fields['name'].widget.attrs['readonly'] = True
    form.fields['uid'].widget.attrs['editable'] = True
    if request.method == 'POST':        
        if form.is_valid():
            #form['user'] = request.user
            f = form.save(commit=False)
            f.user = request.user
            f.company = Company.objects.get(name='Common')
            f.save()
            form.save_m2m()

            shopid = form.instance.id
            name = form.cleaned_data['name']

            return redirect('vendor-shop' , shopid) #thing='%s Registered' %name)

    return render(request, 'shopregister.html', {'form':form})

{% block content %}
<form method="post" action="." enctype="multipart/form-data">{% csrf_token %}
    <table border="0">
        {{ form }}
    </table>
    <input type="submit" value="Submit" />
