Django UpdateView 方法不允许（POST）

Question

当我在更新页面 (http://127.0.0.1:8000/account/15/update) 上单击“保存”时，我得到了

[19/Mar/2021 13:47:18] "GET /account/15/update HTTP/1.1" 200 2311
Method Not Allowed (POST): /account/15/
Method Not Allowed: /account/15/
[19/Mar/2021 13:47:24] "POST /account/15/ HTTP/1.1" 405 0

数据库记录没有得到更新，所以看起来有些事情默默地失败了。查看错误消息，我们似乎最终尝试在“帐户详细信息”页面而不是“帐户更新”页面上进行 POST - 这是怎么发生的？

这是我的帐户\urls.py

from django.urls import path
from .views import (
AccountCreateView,
AccountListView,
AccountDetailView,
AccountUpdateView,
AccountDeleteView
)

app_name = 'account'
urlpatterns = [
path('', AccountListView.as_view(), name='account-list'),
path('create/', AccountCreateView.as_view(), name='account-create'),
path('<int:pk>/', AccountDetailView.as_view(), name='account-detail'),
path('<int:pk>/update', AccountUpdateView.as_view(), name='account-update'),
path('<int:pk>/delete', AccountDeleteView.as_view(), name='account-delete'),
]

这是我的 Accounts\views.py

from django.shortcuts import render, get_object_or_404, redirect

from django.views.generic import (
    CreateView,
    DetailView,
    ListView,
    UpdateView,
    DeleteView
)

from .forms import AccountForm
from .models import Account

class AccountCreateView(CreateView):
    form_class = AccountForm
    template_name = 'Accounts/account_create.html'
    queryset = Account.objects.all().order_by("-pk")

    def form_valid (self, form):
        return super().form_valid(form)

class AccountDetailView(DetailView):

    def get_object(self):
        account_id = self.kwargs.get("pk")
        return get_object_or_404(Account, account_id=account_id)

class AccountUpdateView(UpdateView):
    form_class = AccountForm
    template_name = 'Accounts/account_create.html'

    def get_object(self):
        account_id = self.kwargs.get("pk")
        return get_object_or_404(Account, account_id=account_id)

    def form_valid (self, form):
        return super().form_valid(form)

这是我的 Accounts\account_create.html（我将其用于创建和更新）

{% extends 'base.html' %}
{% block content %}
    <h1>Account Create/Update Page for {{ request.user }} </h1>
    This is the InApp Account Create/Update Page<p/>
    <form action="." method='POST' enctype="multipart/form-data"> {% csrf_token %}
        <table id="accountdetail">
            {{ form.as_table }}
        </table>
        <p/>
        <input type="submit" value="Save"/> &nbsp;&nbsp;
        <button onclick="location.href='/account'" type="button">Cancel</button>
    </form>
{% endblock %}

我错过了什么？谢谢。

HTML 中的表单明确将 POST 数据发送到“.”：

<form action="." method='POST' enctype="multipart/form-data">

所以我相信/account/15/update 会变成/account/15，就像向上移动一个目录一样。如果您真的想使用相同的模板，您可以尝试以下方法：

{% if "update" in request.get_full_path %}
 <form action="{% url 'account-update' account.id %}" method="PUT">
{% else %}
 <form action="{% url 'account-create' account.id %}" method="POST" enctype="multipart/form-data">

另外，请注意 enctype 属性只能与 method="POST" 一起使用
