Django-allauth-如何从Ajax获取表单错误? [英] Django-allauth - How do I get the form errors from Ajax?

问题描述

使用django-allauth，如何通过AJAX登录获取表格错误?

Using django-allauth, how do I obtain form errors via AJAX login?

我将这个视图与我的/signup/网址一起使用:

I am using this view with my /signup/ url:

from allauth.account.views import SignupView

方便地，它接受我的Ajax呼叫:

Conveniently, it accepts my Ajax call:

var signupForm = function(token) {
   $.ajax({ url:"/signup/",
            type:"POST",
            data: {
                "email": $('#user').val(),
                "password1": $('#pass1').val(),
                "password2": $('#pass2').val()
            },
           success: function (){
                location.href = '/';
                window.location.reload(true);
           },
            error:function (er) {
                alert("signup failure...",er);
            }
        });
};

如果表单有问题，它会很不方便地返回:

Inconveniently, if there is a problem with the form, it returns:

错误400:请求错误

error 400: Bad Request

这让我不知道为什么登录失败.我希望能够向用户传达发生了什么情况.她的密码有问题吗?她的电子邮件地址是否已经注册?

This gives me no idea why a login has failed. I would like to be able to convey to the user what happened. Was it a problem with her password? Was her email address already registered?

我可以使用all-auth来完成此操作，还是需要通过javascript编写自己的验证?

Can I accomplish this with all-auth, or do I need to write my own validation from javascript?

推荐答案

我找不到受支持的解决方案，因此被黑了:

I could not find a supported solution, so I hacked it:

from django.http import JsonResponse
from allauth.account.views import SignupView, _ajax_response

class AjaxSignUpView(SignupView):
    def post(self, request, *args, **kwargs):
        form_class = self.get_form_class()
        form = self.get_form(form_class)
        if form.is_valid():
            response = self.form_valid(form)
            return _ajax_response(
                self.request, response, form=form, data=self._get_ajax_data_if())
        else:
            return JsonResponse({'errors': form.errors})
