'SearchForm' 对象没有属性 'get'

Question

我正在尝试使用 DateField 创建 SearchForm，但是当我发送数据 method="post" 时，表单看不到属性 'get'。错误在哪里？

forms.py

class SearchForm(forms.Form):

datee = forms.DateField(input_formats=['%Y-%m-%d'],
    widget=forms.widgets.DateInput(format="%Y-%m-%d"))

views.py

def index(request):
    search_form = search(request)
    context = {'search_form': search_form}
    return render(request, 'name/index.html', context)

def search(request):
    if request.method == 'POST':
        form = SearchForm(data=request.POST)
        if form.is_valid():
            #Do something for examlpe
            HttpResponseRedirect(reverse("name:second"))
    else:
        form = SearchForm()
    search_form = form
    return search_form

index.html

<form method="post" action="{% url 'name:search' %}">
    {% csrf_token %}
    {{ search_form.as_p }}
    <button name="submit">Search</button>
</form>

但我得到这个 log 并且不明白错误在哪里：

Environment:

Answer 1

Django 视图应该 return httpresponse 对象。但是您的搜索视图 return 表单对象代替了。您可以将 serch 视图重写为类似这样的内容以修复错误：

def search(request):
    if request.method == 'POST':
        form = SearchForm(data=request.POST)
        if form.is_valid():
            #Do something for examlpe
            HttpResponseRedirect(reverse("name:second"))
    else:
        form = SearchForm()
    context = {} 
    context['search_form'] = form
    return render(request, 'name/index.html', context)

Form 不应具有 get、post 或其他 dispatched HTTP 动词匹配方法，因为它用于表示数据并对其进行操作（更具体地说，方便地将任何有意义的操作——即除验证和清理之外的任何操作——委托给底层基础设施），不满足 HTTP 请求——后者是视图的责任。

你的 search 视图 return 是一个 SearchForm 实例，而它必须 return 一个 HttpResponse 兼容的对象，这就是错误的来源来自（注意 if response.get('X-Frame-Options') is not None:）。

要解决此问题，请确保从 search 视图 return render(request, 'name/index.html', {'form': search_form})。
