今天講註冊

有不一樣的地方

userAuth/urls.py

...
    path('register/', views.register, name='register') 
...

user.set_password(user.password)
一定要寫這個因為 password 要call func 做加密

userAuth/views.py

...
def register(request):
    if request.method == 'GET':
        registerForm = RegisterForm()
        return render(request, 'userAuth/register.html', {'registerForm':registerForm})
    elif request.method == 'POST':
        registerForm = RegisterForm(request.POST)
        if not registerForm.is_valid():
            return render(request, 'userAuth/register.html', {'registerForm':registerForm})
        user = registerForm.save()
        user.set_password(user.password)
        user.save()
        messages.error(request, '註冊成功')
        return redirect(reverse('main:main'))
...

客製化驗證欄位 def clean_<field>(self)
可以寫一個驗證密碼與確認密碼，就不用在views.py 寫

參考
https://docs.djangoproject.com/en/1.8/_modules/django/contrib/auth/forms/

user Model 欄位
https://docs.djangoproject.com/en/1.8/_modules/django/contrib/auth/forms/

userAuth/forms.py

from django import forms
from django.contrib.auth.models import User

class RegisterForm(forms.ModelForm):
    username = forms.CharField(label='帳號')
    email = forms.EmailField(label='信箱')
    password = forms.CharField(label='密碼', widget=forms.PasswordInput())
    password2 = forms.CharField(label='確認密碼', widget=forms.PasswordInput())

    def clean_password2(self):
        password = self.cleaned_data.get('password')
        password2 = self.cleaned_data.get('password2')
        if password != password2:
            raise forms.ValidationError('密碼和確認密碼不同')
        return password2

    class Meta:
        model = User
        fields = ('username', 'email', 'password', 'password2')

userAuth/templates/userAuth/register.html

{% extends 'main/base.html' %}
{% block content %}
  <h2>註冊</h2>
  <form method="post" action="{% url 'userAuth:register' %}">
    {% csrf_token %}
    {{ registerForm.as_p }}
    <input type="submit" value="註冊">
  </form>
{% endblock %}

就完成了
