Page not found - The current path, matched the last one-CodePudding

I have created an update view. I want to add a button to the post that directs to the update view. However when you click the button you get this error.

404 Page not found
post/<int:pks>/build-log/<int:pk>/update/ [name='build-log-update']
post/75/build-log/127/update/, matched the last one.`

The reason for this error occurring is because it is flipping the PK when you click the button. Example. /post/127/build-log/75/ after button clicked /post/75/build-log/127/update/ you can see it is flipping the PK.

If just just append update to the good url it works fine I cannot figure out why it is flipping the pks

html:

<a class="delete-btn" href='{% url "build-log-delete" pk=log.post_id pkz=log.pk %}'>Delete</a>
<a class="update-btn" href='{% url "build-log-update" pk=log.post_id pkz=log.pk %}'>Update</a>

urls:

path('post/<int:pk>/build-log/<int:pkz>/', views.BuildLogDisplay, name='build-log-view'),
path('post/<int:pk>/build-log/<int:pkz>/delete/', views.BuildLogDelete, name='build-log-delete'), 
path('post/<int:pk>/build-log/<int:pkz>/update/', UpdateBuildLog.as_view(), name='build-log-update')

model:

class BuildLog(models.Model):
    title = models.CharField(max_length=100)
    content = RichTextUploadingField(blank=True, null=True)
    date_posted = models.DateTimeField(default=timezone.now)
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    post = models.ForeignKey('Post', on_delete=models.CASCADE)

    def get_absolute_url(self):
        return reverse('build-log-view', kwargs={'pkz': self.pk})

view:

class UpdateBuildLog(LoginRequiredMixin, UserPassesTestMixin, UpdateView):
    model = BuildLog
    form_class = BuildLogupdateForm
    template = 'blog/buildlog_update.html'
    

    def form_valid(self, form):
        form.instance.author = self.request.user
        return super().form_valid(form)
            


    def test_func(self):
        post = self.get_object()
        if self.request.user.id == post.author_id:
            return True
        return False

CodePudding user response：

The base post URL and the delete URL have pk as the first captured value, while the update URL has pk as the second captured value.

'post/<int:pk>/build-log/<int:pkz>/'
'post/<int:pk>/build-log/<int:pkz>/delete/'
'post/<int:pks>/build-log/<int:pk>/update/'

CodePudding user response：

I had to pass this on the view.

def get_object(self):
return BuildLog.objects.get(pk=self.kwargs["pkz"])
