使用会话的Django视图中“ def”处的语法错误

Question

它位于Django项目中的某个应用程序中，位于该应用程序的views文件中。该应用程序安装在settings.py中，但在调用视图之前会引发错误。

我在CouponForm的“ def”中的“ f”处遇到错误，它说这是一个SyntaxError，但我无法解决问题。urlconf仅引用manageCoupons函数。在此先感谢您的帮助！

views.py：

from models import Coupon

from django.shortcuts import render

from django.http import HttpResponse

def CouponList(req):

    c = Coupon.objects.all()

    return render(req,'coupon_list.html',{'title':'Coupons','coupons':c}

def CouponForm(req1):

    if 'name' in req1.GET and 'desc' in req1.GET:

        name1 = req1.GET['cname']

        desc = req1.GET['desc']

        c = Coupon(name=name1, description=desc)

        c.save()

        success = True

    else:

        success = False

    return render(req1,'coupon.html',{'title':'New Coupon','success':success,})

def CouponDelete(req2):

    if 'name' in req2.GET:

        name1 = req2.GET['name']

        c = Coupon.objects.filter(name=name1)

        c.delete()

        success = True

    else:

        success = False

    return render(req2,'coupon_delete.html',{'title':'Delete Coupon','success':success}

def manageCoupons(request):

    if 'passwrd' in request.GET:

        psswrd = request.GET['passwrd']

        if psswrd == 'password0':

            return CouponList(request)

        elif psswrd == 'password1':

            request.session["function"] = 'cform'

            return CouponForm(request)

        elif psswrd == 'password2':

            request.session["function"] = 'cdelete'

            return CouponDelete(request)

    elif "function" in request.session:

        if request.session["function"] == 'cdelete':

            return CouponDelete(request)

        elif request.session["function"] == 'cform':

            return CouponForm(request)

    else:

        return HttpResponse("<a href='/'>Home</a>")

def CouponList(req):&nbsp; &nbsp; c = Coupon.objects.all()&nbsp; &nbsp; return render(req,'coupon_list.html',{'title':'Coupons','coupons':c})&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ^&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; |&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; You are missing this bracket

Answer 2

您)在此行不见了：render(req2,'coupon_delete.html',{'title':'Delete&nbsp;Coupon','success':success}应该：render(req2,'coupon_delete.html',{'title':'Delete&nbsp;Coupon','success':success})
