URL 使用 PK 的重定向问题

Question

大家好，我遇到了以下错误的主键问题：django.urls.exceptions.NoReverseMatch：找不到 'addteam' 的反向。 'addteam' 不是有效的视图函数或模式名称。

我的应用程序很简单：用户创建一个项目，然后使用按钮到达详细信息页面中的一个页面，以便使用邮件邀请用户...问题是我在创建项目后收到错误

这是我的代码：

urls.py:

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

app_name = 'website'
urlpatterns = [
    url(r'^candidateIndex/$', views.CandidateIndex.as_view(), name='candidate_index'),
    url(r'^HRcreate/$', views.ProjectCreate.as_view(), name='HR_create'),
    url(r'^project/(?P<pk>[0-9]+)/$',views.ProjectDetailView.as_view(), name='ProjectDetails'),
    url(r'^project/(?P<pk>[0-9]+)/invite/$',views.create_invite, name='addteam'),
]

views.py:

from django.shortcuts import render
from django.views import generic
from django.views.generic import TemplateView
from django.views.generic.edit import CreateView, UpdateView, DeleteView
from .forms import InviteForm
from invitations.models import Invitation
from .models import project
from django.core.urlresolvers import reverse

# Create your views here.

class HomePage(TemplateView):
    template_name= 'index.html'

class CandidateIndex(TemplateView):
    template_name= 'candidateIndex.html'

class HRIndex(TemplateView):
    template_name= 'HRindex.html'

class ProjectDetailView(generic.DetailView):
    model = project
    template_name = 'project_details.html'

class ProjectCreate(CreateView):
    model = project
    fields = ['project_name']
    template_name = 'project_form.html'


def create_invite(request, pk):
    if request.method == "POST":
        invite_form = InviteForm(data=request.POST)
        if invite_form.is_valid():
            email1 = invite_form.cleaned_data['email1']
            email2 = invite_form.cleaned_data['email2']
            email3 = invite_form.cleaned_data['email3']
            email4 = invite_form.cleaned_data['email4']
            email5 = invite_form.cleaned_data['email5']
            for i in invite_form.cleaned_data:
                invite = Invitation.create(i)
                invite.send_invitation(request)
            print("The mail was went")
            #return reverse('website:ProjectDetails', kwargs = {'pk' : self.pk} )
        else:
            print("Your form is not valid")
    else:
        invite_form = InviteForm()
    return render(request, 'team_invite.html', {'invite_form': invite_form})

models.py:

from django.db import models
from django.core.urlresolvers import reverse

class project(models.Model):
    project_name = models.CharField(max_length=150)
    created_at = models.DateTimeField(auto_now_add=True)

    def get_absolute_url(self):
        return reverse('website:ProjectDetails', kwargs = {'pk' : self.pk})

    def __str__(self):
        return self.project_name


class Team(models.Model):
    project = models.ForeignKey(project)
    team_name = models.CharField(max_length=150)

    def __str__(self):
        return self.team_name

project_details.html:

{% extends 'base.html' %}
{% block body %}
<div class="container">
  <div class="jumbotron">
    <h2>Welcome to your Project {{project.project_name}} Detail page</h2>
  </div>
  <div class="invite-team">
      <a href="{% url 'website:addteam'%}">GOGO</a>
  </div>
</div>




{% endblock%}

错误：在模板 /Users/raphaelbendenoun/Documents/SoftScores_project_Final/templates/base.html 中，第 8 行出错找不到 'addteam' 的反向。 'addteam' 不是有效的视图函数或模式名称。

--> 第 8 行是引导程序 link ...

Answer 1

下面的行表示您的视图正在接受项目模型的主键。

url(r'^project/(?P<pk>[0-9]+)/invite/$',views.create_invite, name='addteam'),

但是您在下面的视图中并未表明您使用了其中的项目模型。

def create_invite(request, pk):

所以改变

 def create_invite(request, pk):

到

 def create_invite(request):

和

url(r'^project/(?P<pk>[0-9]+)/invite/$',views.create_invite, name='addteam')

到

url(r'^project/invite/$',views.create_invite, name='addteam')

希望你的模板能正常工作。

如果您需要将主键传递给视图，您需要在模板中执行

<a href="{% url 'website:addteam' pk_key_value %}">GOGO</a>

其中pk_key_value应该是一个带有模型对象主键的变量。

下面 link 会让您更清楚。 https://docs.djangoproject.com/en/1.11/topics/http/urls/

发送邮件也请参考 https://docs.djangoproject.com/en/1.11/topics/email/

你好像没有 'imported from django.core.mail'
