【问题描述】：
我需要一个帮助。我需要使用 Django 实现忘记密码功能。我正在使用 Django 注册和登录页面。我的代码如下：
login.html：
{% extends 'base.html' %}
{% block content %}
<h2>Log in</h2>
{% if form.errors %}
<p style="color: red">Your username and password didn't match. Please try again.</p>
{% endif %}
<form method="post">
{% csrf_token %}
{% for field in form %}
<p>
{{ field.label_tag }}<br>
{{ field }}<br>
{% for error in field.errors %}
<p style="color: red">{{ error }}</p>
{% endfor %}
{% if field.help_text %}
<p><small style="color: grey">{{ field.help_text }}</small></p>
{% endif %}
</p>
{% endfor %}
<button type="submit">Log in</button>
<a href="{% url 'signup' %}">New to My Site? Sign up</a>
</form>
{% endblock %}
views.py：
class Signup(View):
""" this class is used for user signup """
def get(self, request):
""" this function used to get the sign up form """
form = UserCreationForm()
return render(request, 'plant/signup.html', {'form': form})
def post(self, request):
""" this function used for post the sign up data """
form = UserCreationForm(request.POST)
if form.is_valid():
form.save()
return redirect('login')
class AuthLogin(View):
""" Its for login """
def get(self, request):
""" this function used to get the login form """
form = AuthenticationForm()
return render(request, 'plant/login.html', {'form': form})
def post(self, request):
""" this function used for post the login data """
form = AuthenticationForm(None, request.POST or None)
if form.is_valid():
login(request, form.get_user())
return redirect('/')
urls.py:
urlpatterns = [
url(r'^$', TemplateView.as_view(template_name="plant/index.html")),
url(r'^logout/$', auth_views.logout,
{'next_page': 'login'}, name='logout'),
url(r'^login/$', core_views.AuthLogin.as_view(), name='login'),
url(r'^signup/$', core_views.Signup.as_view(), name='signup'),
]
在登录页面我应该有forget password 链接。当用户点击它时，将打开重置密码页面，另一个条件是尝试 3 次错误尝试后，forget password 按钮将在 1 小时内不可见。
