无法在管理站点中访问和添加产品？-Django

Question

i get this error in the browser

 Using the URLconf defined in myshop.urls, Django tried these URL patterns, in this order:
       ^admin/ ^$ [name='index']
            ^admin/ ^login/$ [name='login']
            ^admin/ ^logout/$ [name='logout']
            ^admin/ ^password_change/$ [name='password_change']
            ^admin/ ^password_change/done/$ [name='password_change_done']
            ^admin/ ^jsi18n/$ [name='jsi18n']
            ^admin/ ^r/(?P<content_type_id>\d+)/(?P<object_id>.+)/$ [name='view_on_site']
            ^admin/ ^auth/group/
            ^admin/ ^auth/user/
            ^admin/ ^sites/site/
            ^admin/ ^(?P<app_label>auth|sites)/$ [name='app_list']
        The current path, admin/myshop/Product/add/, didn't match any of these.

i am basically a beginner to django and creating my django shop app. i get this error by typing the url http://127.0.0.1:8000/admin/myshop/Product/add/ My admin.py looks like this

from django.contrib import admin
from .models import Category, Product

class CategoryAdmin(admin.ModelAdmin):
list_display=['name','slug']
prepopulated_fields={'slug':('name',)}
admin.site.register(Category, CategoryAdmin)

class ProductAdmin(admin.modelAdmin):
list_display=['name','slug','category','price','stock','avialable','created','updated']
list_filter=['available','created','updated','category']
list_editable=['price','stock','available']
prepopulated_fields=['slug':('name',)}
admin.site.register(Product, ProductAdmin)

This is my models.py file

from django.db import models

# Create your models here.
from django.core.urlresolvers import reverse


class Category(models.Model):
name = models.Charfield(max_length=200, db_index=True)
slug = models.Slugfield(max_length=200, db_index=True, unique=True)

class Meta:
ordering = ('name',)
verbose_name = 'category'
verbose_name_plural = 'categories'

def__str__(self):
return self.name

def get_absolute_url(self):
return reverse('shop:product_list_by_category', args=[self.slug])

class product(models.Model):
category=models.ForeignKey(Category, related_name='products')
name=models.CharField(max_length=200, db_index=True)
slug=models.SlugField(max_length=200, db_index=True)
image=models.ImageField(upload_to'product/%Y/%m/%d',blank=True)
description=models.TextField(blank=True)
price=models.DecimalField(max_digits=10, decimal_places=2)
stock=models.PositiveIntegerField()
available=models.BooleanField(default=True)
created=models.Datetimefield(auto_now_add=True)
updated=models.DatetimeField(auto_now=True)

class Meta:
ordering=('-created',)
index_togetther=(('id','slug'),)

def__str__(self):
return self.name

def get_absolute_url(self):
return reverse('shop:product_detail', args=[self.id,self.slug)

url.py

from django.conf.urls import url
from django.contrib import admin
admin.autodiscover()

urlpatterns = [
    url(r'^admin/', admin.site.urls),

]

I tried to check everything but everything looks ok to me

Answer 1

The problem is with your admin.py file your model from the code you posted is having lowercase product class but in admin you took capital Product, so change the Product to product

from django.contrib import admin
from .models import Category, product

class CategoryAdmin(admin.ModelAdmin):
list_display=['name','slug']
prepopulated_fields={'slug':('name',)}
admin.site.register(Category, CategoryAdmin)

class ProductAdmin(admin.modelAdmin):
list_display=['name','slug','category','price','stock','avialable','created','updated']
list_filter=['available','created','updated','category']
list_editable=['price','stock','available']
prepopulated_fields=['slug':('name',)}
admin.site.register(product, ProductAdmin)

Answer 2

Use these commands for migrating files:

python manage.py makemigrations
python manage.py migrate

Answer 3

You need to use [ or { , that is:

prepopulated_fields***`=['`***slug':('name',)}

or

prepopulated_fields={'slug':('name',)}
