我将使用django制作待办事项列表...我做了一些code...but，它抛出了一个multiplevaluekeyerror

我尝试了c= request.POST.get('content'，False)，但它总是给出假的值

views.py

from django.shortcuts import render
from django.http import HttpResponseRedirect
from .models import TodoItem

# Create your views here.

def home(request):
    return render(request, 'home.html')

def work(request):
    all_todo_items = TodoItem.objects.all()
    return render(request, 'work.html', {'all_items': all_todo_items})

def addTodo(request):
    c = request.POST['content']
    new_item = TodoItem(content = c)
    new_item.save()
    return HttpResponseRedirect('/work/')

def deleteTodo(request, todo_id):
    item_to_delete = TodoItem.objects.get(id=todo_id)
    item_to_delete.delete()
    return HttpResponseRedirect('/work/')

work.html

{% load static %}

urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('', views.home, name='home'),
    path('work/', views.work, name = 'work'),
    path('addTodo/', views.addTodo, name = 'work'),
    path('deleteTodo/<int:todo_id>/', views.deleteTodo, name = 'work'),
]

我没想到errors...but会抛出一个multiplevaluekeyerror

提升django.utils.datastructures.MultiValueDictKeyError：(MultiValueDictKeyError)内容'content‘

python

django

您需要首先提交代码中包含<input name="content">的<form>，以便在view中可以使用`request.POST“Conten值”来获取的值。试试这个：

<div class="container">
      <div class="row">
        <div class="col-sm-11">
          <form action="/addTodo/" method="post">
            {% csrf_token %}
            <div class="form-group">
              <input type="text" class="form-control" placeholder="write your task" name="content">
              <input type="submit" value="submit new task">
            </div>
          </form>
        </div>
      </div>
    </div>
