如何自定义登录错误消息?

你需要从 auth.login auth.LoginView 有一个子类 AuthenticationForm

from django.contrib.auth.views import LoginView
from django.contrib.auth.forms import AuthenticationForm
from django.utils.translation import gettext_lazy as _

class MyAuthForm(AuthenticationForm):
    error_messages = {
        'invalid_login': _(
            "Please enter a correct %(username)s and password. Note that both "
            "fields may be case-sensitive."
        ),
        'inactive': _("This account is inactive."),
    }


class MyLoginView(LoginView):
    authentication_form = MyAuthForm

你可以改变主意 invalid_login

在你的网址.py:

url(r'^login/$', MyLoginView.as_view(), {'template_name': 'login.html'}, name='login'),

我提供另一个答案,它可能不漂亮,但是 如果你有急事 contextmanager )可以帮你工作。它可以适用于许多情况,因为 使用大量的类属性来控制某些东西。

from django.contrib.auth import views
from contextlib import contextmanager
from django.contrib.auth.forms import AuthenticationForm
from django.template.response import TemplateResponse
from django.utils.translation import gettext_lazy


class LoginViewCustom(views.LoginView):
    template_name = 'my_login.html'
    error_messages = {
        'invalid_login': gettext_lazy('...'),
        'inactive': gettext_lazy("..."),
    }

    def post(self, request, *args, **kwargs):
        with self.handle_msg():
            rtn_response: TemplateResponse = super(LoginViewCustom, self).post(request, *args, **kwargs)
        return rtn_response

    @contextmanager
    def handle_msg(self):
        org_msg = AuthenticationForm.error_messages
        AuthenticationForm.error_messages = self.error_messages
        try:
            yield self.error_messages
        finally:
            AuthenticationForm.error_messages = org_msg
