[Django] User 확장과 인증 (실습2)

회원가입하기

1. account app의 views.py에 register_view생성

from django.shortcuts import redirect, render
from django.contrib.auth.forms import AuthenticationForm, UserCreationForm
from django.contrib.auth import authenticate,login,logout

def login_view(request):
    if request.method == 'POST':
        form = AuthenticationForm(request=request, data = request.POST)
        if form.is_valid(): #유효성 검사
            username = form.cleaned_data.get("username")  #클린한 데이터를 get해와서 저장
            password = form.cleaned_data.get("password")
            user = authenticate(request=request, username=username, password=password)
            if user is not None: #유저가 존재할때
                login(request, user)
            return redirect('home')
    else :
        form = AuthenticationForm()
        return render(request, 'login.html',{'form' : form})

def logout_view(request):
    logout(request)
    return redirect('home')

def register_view(request):
    form = UserCreationForm()
    return render(request, 'signup.html',{'form' : form})

2. urls.py에 path 생성

from django.urls import path
from .views import * 

urlpatterns = [
    path('login/', login_view, name="login"),
    path('logout/', logout_view, name="logout"),
    path('register/', register_view, name="signup"),
]

3. signup.html 만들기

{% extends 'base.html' %}

{% block content %}

<h1>Sign up!</h1>
<form action="" method="post" > 
    {%csrf_token%}
    {{form.as_p}}
    <button type="submit">Submit</button>
</form>

{% endblock %}

4. base.html에 sign up 링크 만들기

<li class="nav-item">
    <a class="nav-link" href="{% url 'signup' %}">SignUp</a>
</li>

5. runserver

---

1. signup.html의 action 지정

{% extends 'base.html' %}

{% block content %}

<h1>Sign up!</h1>
<form action="{% url 'signup' %}" method="post" > 
    {%csrf_token%}
    {{form.as_p}}
    <button type="submit">Submit</button>
</form>

{% endblock %}

2. views.py 수정

from django.shortcuts import redirect, render
from django.contrib.auth.forms import AuthenticationForm, UserCreationForm
from django.contrib.auth import authenticate,login,logout

def login_view(request):
    if request.method == 'POST':
        form = AuthenticationForm(request=request, data = request.POST)
        if form.is_valid(): #유효성 검사
            username = form.cleaned_data.get("username")  #클린한 데이터를 get해와서 저장
            password = form.cleaned_data.get("password")
            user = authenticate(request=request, username=username, password=password)
            if user is not None: #유저가 존재할때
                login(request, user)
        return redirect('home')
    else :
        form = AuthenticationForm()
        return render(request, 'login.html',{'form' : form})

def logout_view(request):
    logout(request)
    return redirect('home')

def register_view(request):
    if request.method == 'POST':
        form = UserCreationForm(request.POST)
        if form.is_valid(): #유효성 검사
            user = form.save()
            login(request, user)
        return redirect('home')
    else :
        form = UserCreationForm()
        return render(request, 'signup.html',{'form' : form})

3. runserver

로그인이 된 상태일때만 글쓰기, 로그인이 된 상태일때 -> 로그인,회원가입 태그 보이지 않게

1. base.html 수정

{% if user.is_authenticated %}
<li class="nav-item">
    <a class="nav-link active" aria-current="page" href="#">Write</a>
</li>
{% endif %}

{% if not user.is_authenticated %}
<li class="nav-item">
    <a class="nav-link" href="{% url 'login' %}">Login</a>
</li>
{% endif %}

{% if user.is_authenticated %}
<li class="nav-item">
    <a class="nav-link" href="{% url 'logout' %}">Loout</a>
</li>
{% endif %}

{% if not user.is_authenticated %}
<li class="nav-item">
    <a class="nav-link" href="{% url 'signup' %}">SignUp</a>
</li>
{% endif %}

User 확장

1. account 앱의 models.py 수정 

from django.db import models
from django.contrib.auth.models import AbstractUser #상속

class CustomUser(AbstractUser):
    nickname = models.CharField(max_length=100)
    university = models.CharField(max_length=50)
    location = models.CharField(max_length=200)

2. lionproject의 settings.py에 우리가 상속받아서 추가한 models.py를 쓸거라는 것을 추가 해야한다.( 30번째 줄 즈음)

2-1. setting.py 에 Installed_apps에 admin 관련 줄 주석처리 --> migrate 가능하게 함

2-2. lionproject의 urls.py에 있는 admin도 주석처리

AUTH_USER_MODEL = 'account.CustomUser'

3. migration

3-1. 주석처리했던거 다시 풀어주기!

python manage.py makemigrations
python manage.py migrate

4. account 앱에 forms.py 만들기

from django.contrib.auth.forms import UserCreationForm
from .models import CustomUser

class RegisterForm(UserCreationForm):
    class Meta:
        model = CustomUser
        fields = ['username', 'password1','password2','nickname','location','university']

5. views.py에 register_view 수정

from django.shortcuts import redirect, render
from django.contrib.auth.forms import AuthenticationForm
from django.contrib.auth import authenticate,login,logout

from account.forms import RegisterForm

def login_view(request):
    if request.method == 'POST':
        form = AuthenticationForm(request=request, data = request.POST)
        if form.is_valid(): #유효성 검사
            username = form.cleaned_data.get("username")  #클린한 데이터를 get해와서 저장
            password = form.cleaned_data.get("password")
            user = authenticate(request=request, username=username, password=password)
            if user is not None: #유저가 존재할때
                login(request, user)
        return redirect('home')
    else :
        form = AuthenticationForm()
        return render(request, 'login.html',{'form' : form})

def logout_view(request):
    logout(request)
    return redirect('home')

def register_view(request):
    if request.method == 'POST':
        form = RegisterForm(request.POST)
        if form.is_valid(): #유효성 검사
            user = form.save()
            login(request, user)
        return redirect('home')
    else :
        form = RegisterForm()
        return render(request, 'signup.html',{'form' : form})

6. home.html 상단부분 수정

{% if user.is_authenticated %}
안녕하세요 {{user.location}}에 사는 {{user.university}}{{user.nickname}}
{% endif %}

8. account 앱의 admin.py 수정

from django.contrib import admin
from .models import CustomUser

admin.site.register(CustomUser)

 

9. runserver

 

오류...! home.html에 제대로 안뜬다...!
