django模型表单不保存数据

如何解决django模型表单不保存数据

我想用Django创建一个待办事项应用程序。 我为列表模型创建了一个表单，但是当用户单击“提交”以提交列表时，该表单没有保存，为什么？

这是views.py 我已经创建了表单的实例并将其设置为用户字段，然后保存实例，但事实并非如此

def index(request):
    if request.user.is_authenticated:
        user_ = User.objects.get(username=request.user.username)
        lists = user_.user.all()
        form = listForm()
        if request.method == "POST":
            form = listForm(request.POST)
            if form.is_valid():
                instance = form.save(commit=False)
                instance.user = request.user
                instance.save()
            return HttpResponseRedirect(reverse("index"))
        context = {'lists':lists,'form':form}   
        return render(request,'todolists/index.html',context)
    else:
        return render(request,'todolists/login.html')   

这是索引模板

{% extends "todolists/layout.html" %}
{% block body %}
{% if user.is_authenticated %}
    <div class="center-column">
        <form method="POST" action="{% url 'index' %}"> 
            {% csrf_token %}
            {{form.title}}
            <input type="submit" class="btn btn-info">
        </form>
        <div class="todo-list">
            {% for list in lists %}
                <div class="item-row">
                    <a class="btn btn-sm btn-info" href="{% url 'update' list.id %}">update</a>
                    <a class="btn btn-sm btn-danger" href="{% url 'update' list.id %}">delete</a>
                    <span>{{list}}</span>
                </div>
            {% endfor %}
        </div>
    </div>
{% endif %} 
{% endblock %}

这是urls.py

from django.urls import path
from .import views

urlpatterns = [
   path('',views.index,name='index'),path('update/<str:id>/',views.update,name='update'),path("login",views.login_view,name="login"),path("logout",views.logout_view,name="logout"),path("register",views.register,name="register"),]

这是models.py

from django.db import models
from django.contrib.auth.models import AbstractUser

# Create your models here.
class User(AbstractUser):
    pass

    
class list(models.Model):
    title = models.CharField(max_length=200)
    finished = models.BooleanField(default=False)
    timestamps = models.DateTimeField(auto_now_add=True)
    user = models.ForeignKey(User,on_delete=models.CASCADE,related_name="user")
        
    def __str__(self):
        return self.title

这是表格代码

class listForm(forms.ModelForm):
    title= forms.CharField(label=mark_safe("<span style='color:white;'>Title:</span>"),widget= forms.TextInput(attrs={'placeholder':'Add new task...','class':'form-control'}))
    finished= forms.BooleanField(label=mark_safe("<span style='color:white;'>Finished:</span>"),widget= forms.CheckboxInput(attrs={'style':'width:25px;'}))

    class Meta:
        model = list
        fields = '__all__'

解决方法

尝试将模板文件react-select更新为AsyncSelect，如django docs中所述，这里是link

如果只需要HTML中的loadWorkers(inputValue,callback) { if (inputValue == null || inputValue.length < 3) { // not executing with less than 3 characters callback([]); return; } this.props.actions.getWorkersByName(inputValue,includeLeft).then(response => { let workers = []; if (response && !response.error) workers = getResponseData(response); else { // error,get data from global state. workers = this.props.quickSearchResults; } callback(workers); }); } 字段，请更新forms.py文件

{{ form.title }}
