使用相同的django表单编辑/添加对象

我已经使用了this question的答案,但出于某种原因我没有得到好结果。

我正在尝试为我的编辑表单和添加表单使用相同的模板。这是我的urls.py

url(r'^app/student/new/$', 'edit_student', {}, 'student_new'),
url(r'^app/student/edit/(?P<id>\d+)/$', 'edit_student', {}, 'student_edit'),

我的views.py

def edit_student(request, id=None, template_name='student_edit_template.html'):
if id:
    t = "Edit"
    student = get_object_or_404(Student, pk=id)
    if student.teacher != request.user:
        raise HttpResponseForbidden()
else:
    t = "Add"
    student = Student(teacher=request.user)

if request.POST:
    form = StudentForm(request.POST, instance=student)
    if form.is_valid():
        form.save()

        # If the save was successful, redirect to another page
        redirect_url = reverse(student_save_success)
        return HttpResponseRedirect(redirect_url)

else:
    form = StudentForm(instance=student)

return render_to_response(template_name, {
    'form': form,
    't': t,
}, context_instance=RequestContext(request))

我的forms.py

class StudentForm(ModelForm):
class Meta:
    model = Student
    exclude = ('teacher',)

最后我的模板student_edit_template.html

<h1>{{ t }} Student</h1>
<form action="/app/student/edit/{{ student.id }}" method="post"> {% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Submit" />
</form>

出于某种原因,这是一个404:

Page not found (404)
Request Method: POST
Request URL:    http://192.168.1.3:5678/app/student/edit/

我可能在这里错过了一些简单的东西,但此时我至少需要另外一套眼睛。

提前致谢!

你得到了404,因为/student/edit/需要在尾端有一个id,否则没有路由,当你来自/student/new/时,你还没有id。为/student/edit/创建路径和视图,并在其中放置逻辑以处理在POST上创建记录时的情况。
