包含的URLconf'Project.urls'似乎没有任何模式。创建视图

Question

在我尝试添加基于类的视图以创建对象之前，一切都很好：

urls.py

apps / combustible / urls.py

from django.conf.urls import url, include
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^', include('apps.combustible.urls', namespace='combustible')),
]

apps / combustible / forms.py

from django.conf.urls import url, include
from apps.combustible import views

app_name='comustible'
urlpatterns = [
    #url(r'^consulta_pagos/$', views.consulta_pagos, name='consulta_pagos'),
    url(r'^$', views.index, name='index'),
    url(r'^crear_transaccion/$', views.TransaccionCreate.as_view(), name='crear_transaccion'),
]

apps / combustible / views.py

from django import forms
from apps.combustible.models import Transaccion

class TransaccionForm(forms.ModelForm):
    class Meta:
        model = Transaccion
        fields = '__all__'

        widgets = {
            'empresa': forms.Select(attrs={'class': 'form-control'}),
            'gas': forms.Select(attrs={'class': 'form-control'}),
            'fechaT': forms.DateInput(attrs={'class': 'form-control'}),
            'monto': forms.NumberInput(attrs={'class': 'form-control'}),
            'galones': forms.NumberInput(min_value=0.01,attrs={'class': 'form-control'}),
            'efectuado': forms.CheckboxInput(attrs={'class': 'form-control'}),
        }

我想基于类创建视图，因为在执行manage.py runserver时出现此错误：django.core.exceptions.ImproperlyConfigured：包含的URLconf'HDP_Combustible.urls'似乎没有任何模式。如果您在文件中看到有效的模式，则说明问题可能是由循环导入引起的。
