Question

我创建了一个应用程序，允许注册用户使用表单创建产品。每个注册用户都有一个显示其产品的个人资料页面，只有他们在登录时才能看到。我想创建一个视图，允许未注册的用户通过点击用户名查看任何用户的产品。我怎么做？

以下是产品形式：

class ProductForm(forms.ModelForm):
    class Meta:
        model = Product
        fields = ['name', 'description', 'url', 'product_type', 'price', 'image', 'image_url']
        labels = {
            'name': 'Product Name',
            'url': 'Product URL',
            'product_type': 'Product Type',
            'description': 'Product Description',
            'image': 'Product Image',
            'image_url': 'Product Image URL',
            'price': 'Product Price'
        }
        widgets = {
            'description': Textarea(attrs={'rows': 5}),
        }

产品视图很简单：

    def products(request):
    products = Product.objects.all()
    form = ProductForm()
    return render(request, 'products.html', {'products': products, 'form':form})


def post_product(request):
    # if this is a POST request we need to process the form data
    if request.method == 'POST':
        # create a form instance and populate it with data from the request:
        form = ProductForm(data = request.POST, files = request.FILES)
        # check whether it's valid:
        if form.is_valid():
            # process the data in form.cleaned_data as required
            product = form.save(commit = False)
            product.user = request.user
            product.likes = 0
            product.save()
        # redirect to a new URL:
        return HttpResponseRedirect('/products')

如果我需要展示其他任何内容，请告诉我。

class ProductListView(ListView):
    template_name = 'products.html'
    context_object_name = 'product_list'
    paginate_by = None

    def get_queryset(self):
        username = self.request.GET.get('username',None)
        user = None
        if username:
            try:
                user = User.objects.get(username=username)
            except (User.DoesNotExist, User.MultipleObjectsReturned):
                pass
        if user:
            return Product.objects.filter(user=user)
        return Product.objects.none()

urls.py：

url(r'^product/$', ProductListView.as_view(), name='product_list'),

访问www.example.com/product?username=testuser

等页面

根据你的编辑：

def products(request):
    username = request.GET.get('username',None)
    user = None
    if username:
        try:
            user = User.objects.get(username=username)
        except (User.DoesNotExist, User.MultipleObjectsReturned):
            pass
    if user:
        return Product.objects.filter(user=user)
    else:
        products = Product.objects.all()
    form = ProductForm()
    return render(request, 'products.html', {'products': products, 'form':form})

Django视图用户向访问者显示对象
