我认为 Django 注册 1.0 的子类：

class RegistrationView(RegistrationView):
    pass

我这样做是因为我现在想通过 AJAX 发布帖子。我不确定我必须覆盖哪些方法？有什么例子或建议吗？

这是我的view.py：

{% block content %}
<form method="post" action="" id="registration">

  {{ form.as_p }}

  <input type="submit" value="{% trans 'Submit' %}" />
</form>



 <script>


$('#registration').submit(function(e){
     e.preventDefault(); //prevent default form submit

   $.ajax({

       url: '/accounts/register/',
       type: 'POST',
       contentType: "application/json;charset=utf-8",
       dataType: "json",
       data: {
            'csrfmiddlewaretoken': '{% csrf_token %}',
            'id_username': $("#id_username").val(),
            'id_email': $("#id_email").val()
            },
        success: function() {
            alert('Test');

        },
        error: function(errorThrown){
            console.log(errorThrown);
            alert('Error');
            alert(errorThrown);
        }
    });



});

“registration 1.0”应用程序并没有真正被创建来支持 ajax，所以你有很多重写工作要做。

只是为了使注册工作你需要这样的东西：

import json
from django.http import HttpResponse
from django.views.generic.edit import CreateView
from django.contrib.auth.models import User

from registration.views import RegistrationView


class AjaxableResponseMixin(object):
    def get_form_kwargs(self):
        kwargs = {'initial': self.get_initial()}
        if self.request.method in ('POST', 'PUT'):
            dict_ = self.request.POST.copy()
            del dict_['csrfmiddlewaretoken']
            kwargs.update({
                'data': dict_,
                'files': self.request.FILES,
            })
        return kwargs

    def render_to_json_response(self, context, **response_kwargs):
        data = json.dumps(context)
        response_kwargs['content_type'] = 'application/json'
        return HttpResponse(data, **response_kwargs)

    def form_invalid(self, form):
        response = super(AjaxableResponseMixin, self).form_invalid(form)

        if self.request.is_ajax():
            return self.render_to_json_response(form.errors, status=400)
        else:
            return response

    def form_valid(self, request, form):
        if self.request.is_ajax():
            new_user = self.register(request, **form.cleaned_data)
            data = {
                'pk': new_user.pk,
            }
            return self.render_to_json_response(data)
        else:
            response = super(AjaxableResponseMixin, self).form_valid(request, form)
            return response


class MyRegistrationView(AjaxableResponseMixin, RegistrationView):
    def register(self, request, **cleaned_data):
        del cleaned_data['password2']
        user = User.objects.create_user(data['username'], data['email'], data['password1'])
        return user
