"Key 'current' not found in 'InputForm'. Choices are: ." 在 Django 表单中

Question

我有一个模型，我正在用它制作 Django 表单。我的模型有所有的领域但形式没有？不知道哪里出错了？ models.py:

from django.db import models

class flightInfo(models.Model):

    airCode=models.CharField(max_length=20)
    aircraft_departure=models.CharField(max_length=20)
    departure_time=models.TimeField(auto_now=False, auto_now_add=False)
    aircraft_destination=models.CharField(max_length=20)
    arrivale_time=models.TimeField(auto_now=False, auto_now_add=False)


    airCode2=models.CharField(max_length=20)
    aircraft_departure2=models.CharField(max_length=20)
    departure_time2=models.TimeField(auto_now=False, auto_now_add=False)
    aircraft_destination2=models.CharField(max_length=20)
    arrivale_time2=models.TimeField(auto_now=False, auto_now_add=False)

    airCode3=models.CharField(max_length=20)
    aircraft_departure3=models.CharField(max_length=20)
    departure_time3=models.TimeField(auto_now=False, auto_now_add=False)
    aircraft_destination3=models.CharField(max_length=20)
    arrivale_time3=models.TimeField(auto_now=False, auto_now_add=False)

    start_date=models.DateField()
    end_date=models.DateField()
    current =models.DateField()
    day1=models.BooleanField(default=False)
    day2=models.BooleanField(default=False)
    day3=models.BooleanField(default=False)
    day4=models.BooleanField(default=False)
    day5=models.BooleanField(default=False)
    day6=models.BooleanField(default=False)
    day7=models.BooleanField(default=False)
   
    def __str__(self):
        return self.airCode

forms.py:

from django import forms
from . models import *


class InputForm(forms.Form):

    class Meta:
        model = flightInfo
        
        fields = ['airCode', 'start_date', 'day7', 'current']

views.py:

from django.shortcuts import render
from . models import *
from django.http import HttpResponseRedirect, HttpResponse

from .forms import InputForm


def detail(request):
    print(request.GET)
    print(request.POST)
    if request.method == 'POST':
        print( request.POST.get('current'))

        form = InputForm(request.POST)

        print (form['current'].value())
        print (form.data['current'])

        if form.is_valid():

            print( form.cleaned_data['current'])
            print( form.instance.my_field)

            form.save()
        return HttpResponse('<h1>Hello World</h1>')

和urls.py：

from django.urls import path , include
from . import views
urlpatterns = [

    path('', views.detail),
   
    
]

请帮助我。是的，我正在从表单中获取日期以创建 django 表单的实例，而不是从 django 表单中获取 html 表单。

如果您尝试基于模型创建表单，则 InputForm 应该扩展 ModelForm。您可以了解有关模型表单的更多信息here

from django.forms import ModelForm
from .models import *

class InputForm(ModelForm):

    class Meta:
        model = flightInfo
        
        fields = ['airCode', 'start_date', 'day7', 'current']

"Key 'current' not found in 'InputForm'. Choices are: ." 在 Django 表单中

"Key 'current' not found in 'InputForm'. Choices are: ." in Djangoforms

python

django
