注册功能的实现register

1.在urls.py文件里面：

from users.views import RegisterView,

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

2.在views.py文件里面：

from .forms import RegisterForm,

from django.contrib.auth.hashers import make_password

'''注册'''
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',None)

            if UserProfile.objects.filter(email=user_name):
                return render(request, 'register.html', {'register_form':register_form,'msg': '该邮箱已被注册'}, )
            pass_word = request.POST.get('password',None)
            user_profile = UserProfile()
            user_profile.username = user_name
            user_profile.email = user_name
            user_profile.is_active = False
            user_profile.password = make_password(pass_word)
            user_profile.save()

            # 发送消息
            user_message = UserMessage()
            user_message.user = user_profile
            user_message.message = '欢迎注册'
            user_message.save()


            send_register_email(user_name,'register')
            return  render(request,'login.html')
        else:
            return render(request, 'register.html',{'register_form':register_form},)

这里如果需要用到验证码，请见我的博客里面的验证码功能

3.在forms.py文件里面：（这是需要有验证码的情况）

from captcha.fields import CaptchaField

class RegisterForm(forms.Form):
    email = forms.EmailField(required=True)
    password = forms.CharField(required=True,max_length=16,min_length=5,)
    captcha = CaptchaField(error_messages={'invalid':u'验证码错误'})

3.在template/register.html里面：
在验证码下面添加：

{{ register_form.captcha }} 要是这个样子出错的话，就改用HTML文本：

<img src="/captcha/image/2f3f82e5f7a054bf5caa93b9b0bb6cc308fb7011/" alt="点击获取验证码" class="captcha" /> <input id="id_captcha_0" name="captcha_0" type="hidden" value="2f3f82e5f7a054bf5caa93b9b0bb6cc308fb7011" /> <input autocomplete="off" id="id_captcha_1" name="captcha_1" type="text" />

找到表单数据，在form里面加入： action="{% url 'register' %}" method="post"
在表单结尾之前加入：{% csrf_token %}
注意，表单里面的name属性要和views.py文件里面要传递的属性要相同
判断返回页面的样式，是否显示的是登陆状态，

{% if request.user.is_authenticated %}
...

{% else %}
...

{% endif %}


4.对register.html的post提交的表单经行验证是否合法

在app下面新建一个form.py文件

from django import forms

class RegisterForm(forms.Form):
    email = forms.EmailField(required=True)
    password = forms.CharField(required=True,max_length=16,min_length=5,)
    captcha = CaptchaField(error_messages={'invalid':u'验证码错误'})

5.在register.html里面：
在username的字段经行判断 ：

{% if register_form.errors.password %}errorput{% endif %}
新建一个div 来放置报错信息：

{% for key,error in register_form.errors.items%}{{ error }}{% endfor %}{{ msg }}

6.为了用户体验好，我们在form表单里面添加一个value属性   

value='{{ register_form.email.value }}'
