Django錯誤 - SyntaxError：無效的語法

Question

看來我被卡住了。我需要你的幫助才能解決這個錯誤。 我認爲URL上的正則表達式是爛的。任何幫助都感激不盡。

這是錯誤：

File "/Users/cohen/Documents/project/sanctions/batches/urls.py", line 2, in from . import views File "/Users/cohen/Documents/project/sanctions/batches/views.py", line 23 def detail_businessname(request): ^SyntaxError: invalid syntax

這是我的模型：

# -*- coding: utf-8 -*- 
from __future__ import unicode_literals 

from django.db import models 


class Batches(models.Model): 
    BatchNumber = models.IntegerField(null=True) 
    FileName= models.CharField(max_length=250)

    UploadedBy = models.CharField(max_length=250)

class Individuals(models.Model):

    class Meta: 
     verbose_name_plural = "Individuals" 

    def __str__(self): 
     return self.FullName + '-' + self.Address + '-' + self.City + '-' + '-' + self.State + '-' + self.Country 

這是我的看法：

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

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


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


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

而這些網址：

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.detail_businessname, name="detail_businessname"), 

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

謝謝了很多， 科恩

你錯過封閉託槽

return HttpResponse("<h2>Details for Batches ID:" + str(BatchNumber + "</h2"))
