Question

我正尝试将我的应用程序的URL包含到项目的URL中，如下所述，但似乎有问题，请帮助我找出问题所在。我的项目名称是trydjango，其中是urls.py文件

urlpatterns = [
    path('teacher/', include('teacher.urls')),
    path('admin/', admin.site.urls),
    path('', homeView, name='home'),
]

这是teacher.urls文件

from django.urls import path
from .views import addTeacherView, listTeacherView, teacherIndexView, deleteTeacherView, editTeacherView

app_name = "teacher"
urlpatterns = [
    path('addTeacher/', addTeacherView, name='add-teacher'),
    path('listTeacher/', listTeacherView, name='list-teacher'),
    path('teacherIndex/<int:my_id>/', teacherIndexView, name='teacher-index'),
    path('deleteTeacher/<int:my_id>/',
         deleteTeacherView, name='delete-teacher-view'),
    path('editTeacher/<int:my_id>/', editTeacherView, name='edit-teacher'),
]

在models.py中，我以相反的方式添加了应用名称

class Teacher(models.Model):
    firstName = models.CharField(max_length=72)
    email = models.EmailField()
    salary = models.DecimalField(max_digits=100000, decimal_places=2)

    def get_absolute_url(self):
        return reverse('teacher:edit-teacher', kwargs={'my_id': self.id})

请帮助我发现问题预先感谢！

Answer 1

我相信您缺少一些url调用的名称空间。在模板中，您有{% url 'add-teacher' %}。那应该是{% url 'teacher:add-teacher' %}。寻找老师网址的其他情况。

Answer 2

我您的模板使用的地址是这样的：

<a href="{% url 'add-teacher' %}">Add Teacher</a>

您必须将这种寻址方式更改为此（由于应用teacher）：

<a href="{% url 'teacher:add-teacher' %}">Add Teacher</a>

Django-应用程式内网址无法正常运作
