Question

我正在尝试使用DateField创建SearchForm，但是当我发送data method =“post”时，表单看不到属性'get'。哪里出错？

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

的index.html

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

但是我得到了这个日志，并且不明白哪里出错：

Environment:


Request Method: POST

Django Version: 2.0.5
Python Version: 3.6.3

Django视图应该返回httpresponse对象。但是您的搜索视图会返回表单对象。您可以将serch视图重写为类似的内容以修复错误：

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不应该有get，post或其他dispatch ed动词匹配方法，因为它代表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 - 即除了验证和清理之外的任务 - 委托给底层基础架构），而不是满足HTTP请求 - 后者是视图的责任。

当search视图必须返回SearchForm兼容对象时，HttpResponse视图会返回if response.get('X-Frame-Options') is not None:个实例，这就是错误发生的地方（注意return render(request, 'name/index.html', {'form': search_form})）

要解决此问题，请务必search视图中的function checkIsNull(obj){ let isNull=true; for(let key in obj){ if (obj[key] && typeof obj[key] !== 'function') { isNull = false; } } return isNull; } var objectWithFunctionEmpty={ "name":undefined, "surname":null, "fun": function (){ alert('ciao'); } } var objectWithFunctionFull={ "name":undefined, "surname":"bla bla", "fun": function (){ alert('ciao'); } } checkIsNull(objectWithFunctionEmpty); //true checkIsNull(objectWithFunctionFull); //false。

'SearchForm'对象没有'get'属性
