尝试连接到django服务器时，我在终端上看到“ GET / emp HTTP / 1.1” 404 2159 ...我收到未找到的404页面

Question

由于某些url配置问题，我觉得服务器无法很好地呈现视图。它总是呈现消息Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/emp

这是我的项目结构

|--hrdjango
 |--employee
   |--migrations folder
   |--admin.py
   |--urls.py
    ...
   |views.py

|--hrdjango
  ...
 |--settings.py
 |--urls.py

views.py

from django.shortcuts import render, redirect  
from .forms import EmployeeForm  
from .models import Employee  
# Create your views here.  
def emp(request):  
    if request.method == "POST":  
        form = EmployeeForm(request.POST)  
        if form.is_valid():  
            try:  
                form.save()  
                return redirect('/show')  
            except:  
                pass  
    else:  
        form = EmployeeForm()  
    return render(request,'index.html',{'form':form}) 
def show(request):  
    employees = Employee.objects.all()  
    return render(request,"show.html",{'employees':employees})  
def edit(request, id):  
    employee = Employee.objects.get(id=id)  
    return render(request,'edit.html', {'employee':employee})  
def update(request, id):  
    employee = Employee.objects.get(id=id)  
    form = EmployeeForm(request.POST, instance = employee)  
    if form.is_valid():  
        form.save()  
        return redirect("/show")  
    return render(request, 'edit.html', {'employee': employee})  
def destroy(request, id):  
    employee = Employee.objects.get(id=id)  
    employee.delete()  
    return redirect("/show")  

employee / urls.py

from .import views  
from django.contrib import admin  
from django.urls import path, include
app_name = 'employee'
urlpatterns = [  
    path('', views.emp, name='emp'),  
    path('show',views.show, name='show'),  
    path('edit/<int:id>', views.edit, name='edit'),  
    path('update/<int:id>', views.update, name='update'),  
    path('delete/<int:id>', views.destroy, name='destroy'),
    ]  

hrdjango /网址

from django.contrib import admin  
from django.urls import include, path
from employee import views  

urlpatterns = [  
path('admin/', admin.site.urls),
path('employee/', include('employee.urls')),
path('', views.emp),
]

我希望看到根据我的urls配置渲染的视图，但是似乎无法渲染我的视图，因为它没有看到它。

Answer 1

您没有使用此网址格式为http://127.0.0.1:8000/emp的任何url，而是尝试了例如：

1. http://127.0.0.1:8000/
2. http://127.0.0.1:8000/show

或 employee / urls.py

中定义的其他URL

Answer 2

如果要访问emp(request)视图。

hrdjango / urls

from django.contrib import admin  
from django.urls import include, path
from employee import views  

urlpatterns = [  
    path('admin/', admin.site.urls),
    path('employee/', include('employee.urls')),
    # path('', views.emp), - remove this line
]

然后，例如，您可以发出GET这样的请求。

URI下方将调用emp(request)方法

http://127.0.0.1/employee/

此外，在您的ModelForm Meta类中，您应该指定Employee类而不是Employee类实例。

forms.py

from django import forms 
from .models import Employee 
class EmployeeForm(forms.ModelForm):

    class Meta: 
        model = Employee
        fields = '__all__'

希望对您有帮助。
