Question

const url = 'http://example.com/'; final response = await http.get(url); final decodedResponse = json.decode(response); final yourObject = Class.fromJSON(decodedResponse);：

urls.py

我有urlpatterns = [ path('employee/add_employee/', views.add_employee, name='add-employee'), path('employee/add_employee/add/', views.add_employee_action, name='add-employee-action'), ]页和一些表格可以填写。

add-employee：

views.py

模板：

def add_employee(request):
    personal_form = PersonalEmployeeForm()
    history_form = EmployeeHistoryForm()
    return render(
        request,
        'sections/add_employee.html',
        context={
            'personal_form': personal_form,
            'history_form': history_form,
            }
    )

def add_employee_action(request):
    if request.method == "POST":
        personal_form = PersonalEmployeeForm(request.POST)
        history_form = EmployeeHistoryForm(request.POST)
        if personal_form.is_valid() and history_form.is_valid():
            # here is some logic with models
            return redirect('add-employee')
    else:
        personal_form = PersonalEmployeeForm()
        history_form = EmployeeHistoryForm()
    return render(
        request,
        'sections/add_employee.html',
        context={
            'personal_form': personal_form,
            'history_form': history_form,
        }
    )

按元素提交已经过测试，并且可以与jQuery脚本一起很好地工作。

问题在于，提交无效的表单后，我的页面带有<form id="a-submit-form" action="add/" method="POST"> {% csrf_token %} <div class="column-wrapper"> <div class="column"> <div class="form-wrapper"> {% for field in personal_form.visible_fields %} {% include "elements/forms/form_line.html" %} <br> {% endfor %} </div> </div> <div class="column"> <div class="form-wrapper"> {% for field in history_form.visible_fields %} {% include "elements/forms/form_line.html" %} <br> {% endfor %} </div> </div> </div> <div class="button-bar-wrapper"> <div class="button_bar"> <a class="a-button positive" id="submit">Добавить</a> <a class="a-button" href="{% url 'employee' %}">Сотрудники</a> <a class="a-button" href="{% url 'index' %}">На главуную</a> </div> </div> </form> URL。而且，如果我尝试再次提交表单，则我的页面带有blah-blah/employee/add_employee/add/ URL，这是不正确的。如何使用blah-blah/employee/add_employee/add/add/ URL呈现页面并显示所有错误消息？

Answer 1

这可能是因为您在<form>模板的sections/add_employee.html标记中写了 relative URL。因此，模板包含以下内容：

<form method="post" action="add/">
    ...
</form>

您可以将网址与https://www.vagrantup.com/一起使用：

<form method="post" action="{% url 'add-employee-action' %}">
    ...
</form>

此外，通常使用 same 路径来处理GET和POST请求。因此，实际上您可能只是删除了'add-employee'路径。

表单验证失败后如何呈现模板？
