我使用ClassroomCreateView
来选择一个教室。然后我想显示使用ClassroomDetailView
选择的教室。这将显示该教室中的学生名单。我想我应该可以使用pk并从ModelForm到DetailView进行遍历。如何将pk从ModelForm传递给DetailView?
课堂教学模式
class Classroom(models.Model):
BLOCK_NUMBER = (
('11', 'Block 1-1'),
('12', 'Block 1-2'),
('13', 'Block 1-3'),
('14', 'Block 1-4'),
('21', 'Block 2-1'),
('22', 'Block 2-2'),
('23', 'Block 2-3'),
('24', 'Block 2-4'),
)
class_list = models.TextField()
course_block = models.CharField(max_length=10, choices=BLOCK_NUMBER)
def __str__(self):
return self.get_course_block_display()
def save(self, *args, **kwargs):
super(Classroom, self).save(*args, **kwargs)
# overrides the default save function to parse the class list
studentList = []
studentList = self.class_list.split('\n')
print (studentList)
for line in studentList:
line = line.strip('\r')
s = Student.objects.create(nickname = line, classroom = self)
学生模型
class Student(models.Model):
classroom = models.ForeignKey(Classroom, on_delete=models.CASCADE)
nickname = models.CharField(default='JohnS', max_length=31)
Forms.py
class AttendForm(ModelForm):
class Meta:
model = Classroom
fields = ['course_block']
def __init__(self, *args, **kwargs):
super(AttendForm, self).__init__(*args, **kwargs)
Views.py
class AttendCreateView(CreateView):
model = Classroom
form_class = AttendForm
template_name = 'classroom/attend_form.html'
def get_success_url(self):
return reverse('classroom:random', self.kwargs['pk'])
create_attendance_view = AttendCreateView.as_view()
这是我想念的部分。 course_block
有一个PK,但我没有从形式传递到视图。
class ClassroomDetailView(DetailView):
model = Classroom
template_name = 'classroom/random_list.html'
def get_context_data(self, **kwargs):
class_pk = self.kwargs['pk']
context = super(ClassroomDetailView, self).get_context_data(**kwargs)
students = Student.objects.filter(pk = 'class_pk')
context['students'] = students
return context
detail_classroom_view = ClassroomDetailView.as_view()
urls.py
url(r'^classup/$', create_classroom_view, name='classroom'),
url(r'^attend/$', create_attendance_view, name='students'),
url(r'^(?P<pk>[0-9]+)/$', detail_classroom_view, name='random'),
如何从我的形式选择详细视图去(可能使用选择的PK)?
显示你的'urls.py',即'教室:随机'是什么。另外,发生了什么?你会得到一个错误,模板中有错误的链接,还有其他的东西吗? –
上面编辑显示urls.py。当我使用self.object.id时,在AttendCreateView上提交AttendForm后,ClassroomDetailView中的id#会自动增加。即.../45 /然后/ 46 /等等。我在ClassroomDetailView中打印了一个print语句来打印self.kwargs ['pk'],它会打印出“none”。没有任何错误。 –
好吧,只有现在我明白你想要做什么。它实际上非常类似于[今日堆栈溢出的前一个问题](https://stackoverflow.com/questions/45699023/displaying-other-attribute-values-if-one-is-known-in-django-template/45699325 ),但是她正在使用基于函数的视图('index'),您正试图使用'CreateView'。我同意你对评论的回答,如果我使用基于类的视图,那么我将使用[FormView](https://docs.djangoproject.com/en/1.11/ref/class-based-意见/通用编辑/#FormView控件)。 –
