Question

UPDATE3

我通过再次阅读教程后添加更多代码解决了问题，但得到错误'WSGIRequest'对象在按下按钮

后没有属性'电子邮件'

按下保存按钮后链接没有查询字符串

def post_new(request):

    #post = get_object_or_404(Post)

    #form = PostForm()

    #return render_to_response(request, 'registration.html', {'pk': 12})

    #return render(request, 'registration.html', {'form': form})
    if request.method == "POST":
        form = PostForm(request.POST)
        if form.is_valid():
            post = form.save(commit=False)

            #post.author = request.user

            post.Email = request.Email

            post.ProjectName = request.ProjectName

            post.UserName = request.UserName

            post.UserType = request.UserType

            post.BusinessType = request.BusinessType

            post.published_date = timezone.now()

            post.publish()
            #self.published_date = timezone.now()
            return redirect('post_detail', pk=post.pk)

            #with open('/home/martin/Downloads/site1/site1/reg/newusers.csv', 'a') as csvfile:

             #fieldnames = ['name','email address','project','initial password','userType','contact','businessType','company']

             #writer = csv.DictWriter(csvfile, fieldnames=fieldnames)

             #if isexist == 0:

            return redirect('hello.html', pk=post.pk)
    else:
        form = PostForm()
    return render(request, 'registration.html', {'form': form})

UPDATE2

尝试了很多方法后，仍有错误，请下载 https://drive.google.com/file/d/0Bxs_ao6uuBDUdHFQalFmQmY3U2c/view?usp=sharing

UPDATE1

<form method={% url 'post_detail' %}" method="post"" class="post-form">{% csrf_token %}

在上述更新后，它仍然无法运行post_detail

只有

[25/May/2016 04:07:39] "GET /reg/?csrfmiddlewaretoken=uwMaoReQGeVFVdVdJKmsNWApxVIjyDna&Email=a&ProjectName=a&UserName=a&Company=a&Contact=a&InitialPassword=234&UserType=Cyberport+Tenant&BusinessType=Building HTTP/1.1" 200 2276

它没有转到hello.html，所以我猜它还没有运行post_detail 我不明白为什么它在url使用函数名称时传递

def post_detail(request, pk):

    post = get_object_or_404(Post, pk=pk)

    if request.method == "POST":

        form = PostForm(request.POST, instance=post)

        if form.is_valid():

            post = form.save(commit=False)

            post.author = request.user
            post.Email = request.Email

            post.ProjectName = request.ProjectName

            post.UserName = request.UserName

            post.Company = request.Company

            post.Contact = request.Contact

            post.InitialPassword = request.InitialPassword

            post.UserType = request.UserType

            post.BusinessType = request.BusinessType

            post.published_date = timezone.now()

            self.published_date = timezone.now()

            #isexist = os.path.isfile('newusers.csv') 

            #with open('/home/martin/Downloads/site1/site1/reg/newusers.csv', 'a') as csvfile:

             #fieldnames = ['name','email address','project','initial password','userType','contact','businessType','company']

            #writer = csv.DictWriter(csvfile, fieldnames=fieldnames)

            #if isexist == false:

             #writer.writeheader()

            #writer.writerow({'name': request.user, 'email address': request.Email, 'project': request.ProjectName, 'initial password': request.InitialPassword,'userType': request.UserType, 'contact': request.Contact, 'businessType': request.BusinessType, 'company': request.Company,})


            return redirect('hello.html', pk=post.pk)

    else:
    render(request, 'hello.html', {'form': form})

        #form = PostForm(instance=post)



    return render(request, 'hello.html', {'form': form})

我跟随django女孩网并感觉非常困难，期望去/ reg填写表格并按保存按钮然后转到网络/reg/<a number>

只需按下保存按钮

即可触发功能

它有错误

使用参数'（）'和关键字反转'reg / {{post.pk}} /' 没有找到参数“{}”。尝试了0种模式：[]

然后尝试主键pk，又得到了另一个错误

Answer 1

这不是有效的语法：

<form method={% url 'post_detail' %}" method="post"" class="post-form">

您要将表单发布到的网址应位于action属性中：

<form action="{% url 'post_detail' %}" method="post"" class="post-form">

Answer 2

urls.py

from django.conf.urls import url
from views import post_detail
urlpatterns = [
   url(r'^reg/(?P<pk>[0-9A-Za-z]+)/$',
       post_detail,
       name='post_detail'),
]

template.html
从视图传递“pk”值

<form action="{% url 'post_detail' pk=pk %}" method="post" class="post-form">

模板中的url结构是 {％url'命名空间：名称'args，kwargs在这里％}}

Answer 3

我使用post而不是request 并在post_new中添加更多代码

def post_new(request):

    #post = get_object_or_404(Post)

    #form = PostForm()

    #return render_to_response(request, 'registration.html', {'pk': 12})

    #return render(request, 'registration.html', {'form': form})

    if request.method == "POST":

        form = PostForm(request.POST)

        if form.is_valid():

            post = form.save(commit=False)

            #post.author = request.user

            #post.Email = request.Email

            #post.ProjectName = request.ProjectName

            #post.UserName = request.UserName

            #post.Company = request.Company

            #post.Contact = request.Contact

            #post.InitialPassword = request.InitialPassword

            #post.UserType = request.UserType

            #post.BusinessType = request.BusinessType

            #post.published_date = timezone.now()

            #post.publish()

            #self.published_date = timezone.now()

            #return redirect('post_detail', pk=post.pk)

            isexist = os.path.isfile('/home/martin/Downloads/site1/site1/reg/newusers.csv') 

            with open('/home/martin/Downloads/site1/site1/reg/newusers.csv', 'a') as csvfile:

             fieldnames = ['name','email address','project','initial password','userType','contact','businessType','company']

             writer = csv.DictWriter(csvfile, fieldnames=fieldnames)

             print "isexist"

             print isexist

             if isexist == 0:

              writer.writeheader()

             writer.writerow({'name': post.UserName, 'email address': post.Email, 'project': post.ProjectName, 'initial password': post.InitialPassword,'userType': post.UserType, 'contact': post.Contact, 'businessType': post.BusinessType, 'company': post.Company,})



            return render(request, 'approval.html', {'form': form})

    else:

        form = PostForm()

    return render(request, 'registration.html', {'form': form})

'WSGIRequest'对象没有属性'Email'
