Question

我要使用django来创建待办事项列表...我做了一些代码...但是它抛出了一个multivaluekeyerror

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

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'),
]

我没有期待任何错误...但是它引发了一个multivaluekeyerror

提高MultiValueDictKeyError（key） django.utils.datastructures.MultiValueDictKeyError：'内容'

Answer 1

您需要首先提交代码中包含<form>的{{1}}，以便在<input name="content">中可以使用view`。试试这个：

request.POST["conten"] to get value of

MultiValueDictKeyError：'内容'
