보기를 호출해야 할 때 PK를 관리하는 방법

Question

안녕 내 개인 키에 문제가 있습니다. 누군가가 나에게 손을 댈 수 있다면 큰 문제가 될지 모르겠다.

내가 얻을 errror은 다음과 같습니다

class Team(models.Model): 
    team_name = models.CharField(max_length=100, default = '') 
    team_hr_admin = models.ForeignKey(MyUser, blank=True, null=True) 
    members = models.ManyToManyField(MyUser, related_name="members") 

    def __str__(self): 
     return self.team_name 


class Project(models.Model): 
    name = models.CharField(max_length=250) 
    team_id = models.ForeignKey(Team, blank=True, null=True) 
    project_hr_admin = models.ForeignKey('registration.MyUser', blank=True, null=True) 
    candidat_answers = models.ManyToManyField('survey.response') 

    def get_absolute_url(self): 
     return reverse('website:ProjectDetails', kwargs = {'pk1' : self.pk}) 

    def __str__(self): 
     return self.name

내 모델은 다음과 같습니다 객체 PK 또는 슬러그 중 하나를 호출해야

내 URL을 :

urlpatterns = [ 
    url(r'^hr_index/$', views.HRIndex.as_view(), name='hr_index'), 
    url(r'^candidate_index/$', views.CandidateIndex.as_view(),name='candidate_index'), 
    url(r'^employee_index/$', views.EmployeeIndex.as_view(),name='employee_index'), 
    url(r'^addproject/$', views.ProjectCreate.as_view(), name='add_project'), 
    url(r'^project/(?P<pk1>[0-9]+)/addteam/$', views.TeamCreate.as_view(), name='add_team'), 
    url(r'^project/(?P<pk1>[0-9]+)/linkteam/$', views.LinkTeam.as_view(), name='link_team'), 
    url(r'^project/(?P<pk1>[0-9]+)/linkteam2/$', views.TeamSelect, name='team_select'), 
    url(r'^project/(?P<pk1>[0-9]+)/$',views.ProjectDetailView.as_view(), name='ProjectDetails'), 
    url(r'^project/(?P<pk1>[0-9]+)/api/chart/data2/$',views.TeamChartData.as_view(), name='TeamChartData'), 
    url(r'^project/(?P<pk1>[0-9]+)/(?P<pk2>[0-9]+)/$',views.EmployeeDetailView.as_view(), name='EmployeDetails'), 
    url(r'^project/(?P<pk1>[0-9]+)/(?P<pk2>[0-9]+)/api/chart/data/$',views.EmployeeChartData.as_view(), name='EmployeeChartData'), 

나는 무엇을 여기에서 엉망 이냐?

Answer 1

DetailView 님의 get_object 메서드는 pk url 인자를 찾고 있습니다. pk1 URL 인수 만 있기 때문에 오류가 발생합니다.

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

을하거나 EmployeeDetailView에서했던 것처럼 get_object 메소드를 오버라이드 (override) : 당신은 pk에 URL의 인수 이름을 변경해야합니다.

당신은 또한이 같은 ProjectDetailView 내부 pk_url_kwarg을 정의하기 위해 시도 할 수 있습니다 : 당신이 URL 패턴을 변경하거나 get_object을 재정의 할 필요가 없습니다이 경우

class ProjectDetailView(generic.DetailView, LoginRequiredMixin): 
    #import pdb; pdb.set_trace() 
    model = Project 
    template_name = 'project_details.html' 
    pk_url_kwarg = 'pk1' 

합니다.
