我正在学习Django,并且从CreateView重定向回时遇到问题,我想重定向到BookDetail页面,该页面包含由CreateView创建的书实例列表。 models.py:
class BookInstance(models.Model):
"""Model representing a specific copy of a book (i.e. that can be borrowed from the library)."""
id = models.UUIDField(primary_key=True, default=uuid.uuid4, help_text='Unique ID for this particular book across whole library')
book = models.ForeignKey('Book', on_delete=models.SET_NULL, null=True)
imprint = models.CharField(max_length=200)
due_back = models.DateField(null=True, blank=True)
borrower = models.ForeignKey(User, on_delete=models.SET_NULL, null=True, blank=True)
LOAN_STATUS = (
('m', 'Maintenance'),
('o', 'On loan'),
('a', 'Available'),
('r', 'Reserved'),
)
status = models.CharField(
max_length=1,
choices=LOAN_STATUS,
blank=True,
default='m',
help_text='Book availability',
)
class Meta:
ordering = ['due_back']
permissions = (("can_mark_returned", "Set book as returned"),)
def __str__(self):
"""String for representing the Model object."""
return f'{self.id} ({self.book.title})'
@property
def is_overdue(self):
if self.due_back and date.today() > self.due_back:
return True
return False
views.py
class BookInstanceCreate(PermissionRequiredMixin, CreateView):
model = BookInstance
fields = '__all__'
permission_required = 'catalog.can_mark_returned'
initial = {'Book': Book}
success_url = reverse_lazy('book-detail')
urls.py
urlpatterns += [
path('book/create/instance', views.BookInstanceCreate.as_view(), name='book_create_instance'),
path('book/<int:pk>', views.BookDetailView.as_view(), name='book-detail'),
]
success_url在这里似乎不起作用,因为重定向URL需要有关书主键的信息。我已经尝试了几种选择。 `
next = request.POST.get('next', '/')
return HttpResponseRedirect(next)
return HttpResponseRedirect(request.META.get('HTTP_REFERER', '/'))
但它似乎对我不起作用。有人可以指导我如何编辑视图,以便在提交表单后将其重定向吗?
编辑:有我的模板代码:
{% extends "base_generic.html" %}
{% block content %}
<form action="" method="post">
{% csrf_token %}
<table>
{{ form.as_table }}
</table>
<input type="submit" value="Submit" class='btn btn-dark'>
<input type="hidden" name="next" value="{{ request.path }}">
</form>
{% endblock %}
答案 0 :(得分:0)
您需要定义get_success_url
方法,而不是静态的success_url
属性:
class BookInstanceCreate(PermissionRequiredMixin, CreateView):
...
def get_success_url(self):
return reverse('book-detail', kwargs={'pk': self.object.pk})
