Question

嗨stackoverflow人，

在我的项目中，我尝试编写一个视图，它将管理外部api，它将用于获取某些数据，呈现它们并将它们存储在数据库中。

当我尝试访问我的视图时，遇到以下错误

Exception Type: AttributeError at /commande/recherche
Exception Value: 'Commande' object has no attribute '__name__'

我的 models.py：

from django.db import models


class Client(models.Model):
    client = models.IntegerField(null=True)


class Commandes(models.Model):
    date_debut = models.DateField()
    date_fin = models.DateField()
    id_groups = models.CharField(max_length=100)
    id_client = models.ForeignKey(Client)


class Commande(models.Model):
    id_flux = models.CharField(max_length=100, null=True, blank=True)
    id_commande = models.CharField(max_length=100, null=True, blank=True)
    id_client = models.ForeignKey(Client)

我的 views.py ：

from django.shortcuts import render
from http.client import HTTPConnection
from urllib.parse import urlparse, urlunparse
from .form import CommandesForm, CommandeForm
import requests

def resultat(request):
    return render(request, 'commands/resultat.html')


def recherche(request):
    if request.method == 'POST':
        if 'Commandes' in request.POST:
            pass

        if 'Commande' in request.POST:
            pass
    else:
        formCommandes = CommandesForm()
       formCommande = CommandeForm()

    return render(request, 'commands/recherche.html', {'formCommandes': formCommandes })

我的 form.py ：

from django import forms
from .models import Commande, Commandes


class CommandesForm(forms.ModelForm):
    class Meta:
        model = Commandes()
        fields = ('date_debut', 'date_fin', 'id_groups')


class CommandeForm(forms.ModelForm):
    class Meta:
        model = Commande()
        fields = ('date_debut', 'date_fin', 'id_groups', 'id_client', 'id_flux',
                  'id_commande')

这是我需要管理的以下异常：＆＃39; COMMANDE＆＃39;对象没有属性＆＃39; 名称＆＃39;

我知道＆＃39; 名称＆＃39;属性在类中而不是实例中。我无法弄清楚的事实是，为什么例外情况会随着Commande＆＃39;而提出。对象而不是＆＃39;命令＆＃39;对象

django＆＃39; Commande＆＃39;对象没有属性＆＃39; __ name_
