Django錯誤---索引（）缺少1所需的位置參數：'pk'

我嘗試打開路徑時出現此錯誤。它需要一個PK在我的def，我插入它，但問題仍然存在。如果有人能幫忙，我會很多欠你的！Django錯誤---索引（）缺少1所需的位置參數：'pk'

這是錯誤我在瀏覽器：

我分批

from django.conf.urls import url 
from . import views 

urlpatterns = [ 
    # /batches/ 
    url(r'^$', views.index, name='index'), 

    # /batches/2 
    url(r'^(?P<batches_id>[0-9]+)/$',views.detail, name="detail"), 

    # businessname/1 
    url(r'^(?P<businessname_id>[0-9]+)/$',views.index_businessname, name="detail_businessname"), 

    # individuals/1 
    url(r'^(?P<individuals_id>[0-9]+)/$', views.index_individuals, name="detail_individuals"), 
]

URL和意見：

# -*- coding: utf-8 -*- 
from __future__ import unicode_literals 
from .models import BusinessName 
from .models import Individuals 
from .models import Batches 

from django.shortcuts import render 
from django.http import HttpResponse 

# Create your views here. 
def index(request, pk): 
    all_Batches = Batches.objects.all() 
    html = '' 
    for batch in all_Batches: 
     url = '/batches/' + str(batch.id) + '/' 
     html += '<a href="#"' + url + '">' + str(batch.BatchNumber)+ '</a><br>' 
    return HttpResponse(html) 

def detail(request, batch_id): 
    return HttpResponse("<h2>Details for Batches ID:" + str(batch_id) + "</h2") 


def index_businessname(request): 
    all_BusinessNames = BusinessName.objects.all() 
    html = '' 
    for bn in all_BusinessNames: 
     url = '/businessname/' + str(bn.id) + '/' 
     html += '<a href="#"' + url + '">' + bn.FullName + '</a><br>' 
    return HttpResponse(html) 

def detail_businessnames(request, bn_id): 
    return HttpResponse("<h2>Details for Business Names ID:" + str(bn_id) + "</h2") 

def index_individuals(request): 
    all_individuals = Individuals.objects.all() 
    html = '' 
    for i in all_individuals: 
     url = '/individuals/' + str(i.id) + '/' 
     html += '<a href="#"' + url + '">' + i.FullName + '</a><br>' 
    return HttpResponse(html) 


def detail_individuals(request, i_id): 
    return HttpResponse("<h2>Details for Individual Names ID:" + str(i_id)+ "</h2")

謝謝你在前進，科恩

查看預計'pk'從url傳遞，但你的url模式不包括'pk'。 – anuragal

索引視圖有兩個參數。您只寫的網址爲request。您必須給pk作爲輸入，就像detail URL

謝謝Ananthu！ – Cohen

您的網址/批次/沒有參數。所以，你的索引視圖應

def index(request): 
    # ......

謝謝哈倫！ – Cohen

在您的網址包含pk。

更改您的網址是這樣，

url(r'(?P<pk>\d+)/$', views.index, name='index'),

代替，

# /batches/ 

url(r'^$', views.index, name='index'),

OR，

，如果你不及格pk到的意見，然後從index視圖刪除pk在下面顯示。

def index(request): 
    all_Batches = Batches.objects.all() 
    html = '' 
    for batch in all_Batches: 
     url = '/batches/' + str(batch.id) + '/' 
     html += '<a href="#"' + url + '">' + str(batch.BatchNumber)+ '</a><br>' 
    return HttpResponse(html)
