python - 使用会话的 Django 视图中的“def”处的语法错误

Question

这是在 Django 项目的应用程序中，在该应用程序的视图文件中。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”处收到一个错误，它说这是一个 SyntaxError，但我无法找到问题所在。urlconf 仅引用 manageCoupons 函数。提前感谢您的帮助！

视图.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>")

Answer 1

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

Answer 2

您)在这一行缺少：

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

应该：

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