在 Django 中使用内置重置密码和密码更改时如何显示错误消息

Question

我正在处理一些用户忘记密码以及使用 Django 内置功能重置密码的问题，但我正在使用我的模板来呈现页面和表单。我想要一种方法来呈现错误消息或成功消息，以便用户了解在密码太短的情况下发生了什么。

urls.py

from django.urls import path
from . import views
from django.contrib.auth import views as auth_views

urlpatterns = [
    path('', views.Dashboard, name='dashboard'),
    path('login/', views.Login, name='login'),
    path('logout/', views.Logout, name='logout'),
    path('register/', views.Register, name='register'),
    path('forgetpassword/', views.ForgetPassword, name='forgetpassword'),
    path('password_change/', auth_views.PasswordChangeView.as_view(
        template_name='auth/password/change-password.html'), name='password_change'),
    path('password_change/done/', auth_views.PasswordChangeDoneView.as_view(
        template_name='auth/password/change-password-done.html'), name='password_change_done'),

变化-password.html

{% extends 'auth/base.html' %}
{% load static %}
{% block content %}
<div class="page-wrapper" style="height: 100vh!important;">
    <div class="page-content--bge5">
        <div class="container">
            <div class="login-wrap">
                <div class="login-content">
                    <div class="login-logo">
                        <a href="#">
                            <img src="{% static 'images/icon/logo-new.png' %}" alt="CoolAdmin">
                        </a>
                    </div>
                    {% if messages %}
                    {% for message in messages %}
                    <div class="alert alert-{{message.tags}} with-close alert-dismissible fade show">
                        {{message}}
                        <button type="button" class="close" data-dismiss="alert" aria-label="Close">

                        </button>
                    </div>
                    {% endfor %}
                    {% endif %}
                    <div class="login-form">
                        <form method="POST">
                            {% csrf_token %}
                            <div class="form-group">
                                <label>Current Password</label>
                                <input class="au-input au-input--full" type="password" name="old_password" id="id_old_password" placeholder="Current Password" required>

Answer 1

表格已经在它的实例中有错误。出于某种原因，人们使用消息框架来显示错误，这实际上比简单地使用模板中的表单更困难。该视图将表单实例传递给您的模板，以便您可以使用它来呈现表单并呈现它的错误。在您的模板中试试这个：

呈现非字段错误：

{% for error in form.non_field_errors %}
    {{ error }}
{% endfor %}

要呈现字段错误，请使用 form.field_name.errors:

{% for error in form.new_password1.errors %}
    {{ error }}
{% endfor %}

作为注释手动呈现表单（通过自己编写标签<input ....>）无缘无故地增加了制作表单的难度。也许有人可能不喜欢使用默认呈现的表单，但是有一些方法可以在表单的 class 中或使用一些包来自定义它。请参阅 django-widget-tweaks and django-crispy-forms 两个很棒的包来自定义表单呈现。

我按照之前的回答解决了问题。我在 HTML 中添加了错误标签，这使它完美地工作并使用一些样式很好地显示了错误。

{% for error in form.old_password.errors %}
    <div class="alert alert-danger with-close alert-dismissible fade show">
        {{error}}
        <button type="button" class="close" data-dismiss="alert" aria-label="Close">
            <span aria-hidden="true">&times;</span>
        </button>
    </div>
{% endfor %}

{% for error in form.new_password1.errors %}
    <div class="alert alert-danger with-close alert-dismissible fade show">
        {{error}}
        <button type="button" class="close" data-dismiss="alert" aria-label="Close">
            <span aria-hidden="true">&times;</span>
        </button>
    </div>
{% endfor %}

{% for error in form.new_password2.errors %}
    <div class="alert alert-danger with-close alert-dismissible fade show">
        {{error}}
        <button type="button" class="close" data-dismiss="alert" aria-label="Close">
            <span aria-hidden="true">&times;</span>
        </button>
    </div>
{% endfor %}

<div class="login-form">
    <form method="POST">
        {% csrf_token %}
        <div class="form-group">
            <label>Current Password</label>
            <input class="au-input au-input--full" type="password" name="old_password" id="id_old_password" placeholder="Current Password" required>
        </div>
        <div class="form-group">
            <label>New Password</label>
            <input class="au-input au-input--full" type="password" name="new_password1" id="id_new_password1" placeholder="New Password" required>
        </div>
        <div class="form-group">
            <label>New Password</label>
            <input class="au-input au-input--full" type="password" name="new_password2" id="id_new_password2" placeholder="New Password" required>
        </div>
        <button class="au-btn au-btn--block au-btn--green m-b-20" type="submit">Change Password</button>
    </form>
</div>
