django 用户注册功能实现

增加views的类

class RegisterView(View):
    def get(self, request):
        return render(request, 'register.html', {})

增加urls.py的url

url(r'^register/$', RegisterView.as_view(), name="register")

这样可以调用register.html了，修改index.html的注册按键的跳转代码

<a style="color:white" class="fr registerbtn" href="{% url 'register' %}">注册</a>

这样就实现了点击 注册 跳转到register.html的功能

然后修改regiter.html文件

在开头增加{% load staticfiles %}为了后面可以用static的相对地址

{% load staticfiles %}

因为我们的settings下设定过static的url，
所以可以直接修改

<link rel="stylesheet" type="text/css" href="../css/reset.css">

为

<link rel="stylesheet" type="text/css" href="{% static 'css/reset.css' %}">

同理修改其它的静态文件static相对路径

安装第三方验证码库

https://github.com/mbi/django-simple-captcha

安装方法

https://django-simple-captcha.readthedocs.io/en/latest/usage.html#installation

安装0.4.6版本！！！！！

pip install  django-simple-captcha==0.4.6

发现出现问题连接不上服务器
Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError(<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x000000000
40929E8>, 'Connection to pypi.org timed out. (connect timeout=15)')': /simple/django-simple-captcha/
那只能换连接源了

pip install  django-simple-captcha==0.4.6 -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

OK！！！安装好

在settings的INSTALLED_APPS增加captcha

生成数据库迁移

可以看到数据库的表了

在urls.py的urlpatterns内增加

url(r'^captcha/', include('captcha.urls'))

用到include需要增加

from django.conf.urls import include

在forms.py内增加对注册的验证

from captcha.fields import CaptchaField

class RegisterForm(forms.Form):
    email = forms.EmailField(required=True)
    password = forms.CharField(required=True, min_length=6)
    captcha = CaptchaField()

在views.py下修改RegisterView类实例化form并render给html

class RegisterView(View):
    def get(self, request):
        register_form = RegisterForm()
        return render(request, 'register.html', {'register_form':register_form})

然后在register.html内的验证码出增加代码去支持验证码功能

<div class="form-group marb8 captcha1 ">
                            <label>验&nbsp;证&nbsp;码</label>
                            {{ register_form.captcha }}
                        </div>

这样就可以支持验证码了。如下图

接下来修改验证form的逻辑，为了让输出的验证码错误信息为中文，修改form

class RegisterForm(forms.Form):
    email = forms.EmailField(required=True)
    password = forms.CharField(required=True, min_length=6)
    captcha = CaptchaField(error_messages={'invalid': u'验证码错误'})

然后修改views.py增加POST的表单提交验证和保存功能,这里需要用到密码加密的头文件

from django.contrib.auth.hashers import make_password

class RegisterView(View):
    def get(self, request):
        register_form = RegisterForm()
        return render(request, 'register.html', {'register_form':register_form})

    def post(self, request):
        register_form = RegisterForm(request.POST)
        if register_form.is_valid():
            user_name = request.POST.get("email", "")
            pass_word = request.POST.get("password", "")
            user_profile = UserProfile()
            user_profile.username = user_name
            user_profile.email = user_name
            user_profile.password = make_password(pass_word)
            user_profile.save()
        print "test"
