Wie man PK verwaltet, wenn eine Ansicht damit aufgerufen werden muss

Question

Hallo Leute, ich habe ein Problem mit meinen privaten Schlüsseln. Ich weiß nicht, was das Problem ist, wenn jemand mir eine Hand geben könnte, würde es sehr geschätzt werden.

die errror, die ich erhalte, ist:

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 

meine Ansichten:

Allgemeindetailansicht ProjectDetailView muss entweder mit einem Objekt pk oder eine Schnecke

meine Modelle sind die folgenden genannt werden

meine Urls:

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'), 

Was vermassele ich hier?

Answer 1

DetailViewget_object Methode sucht nach pk URL Argument. Weil Sie nur pk1 URL-Argument haben, es Fehler zu erhöhen. Sie müssen pk Argument URL benennen:

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

oder außer Kraft setzen get_object Methode, wie Sie in EmployeeDetailView tat.

können Sie auch versuchen, pk_url_kwarg innerhalb ProjectDetailView wie folgt zu definieren:

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

In diesem Fall müssen Sie nicht URL-Muster zu ändern oder get_object außer Kraft setzen.
