[Django] Template 상속

by 안녕주 2021. 7. 19.

navbar 달기!

1. https://getbootstrap.com/docs/5.0/getting-started/introduction/ 에 가서 CSS,JS 코드 복붙

2. https://getbootstrap.com/docs/5.0/components/navbar/ 에가서 navbar도 복붙

Template 상속!

 중복되는 코드부분을 base.html에 만들어 두고 다른 html들이 템플릿을 상속받아서 사용할 수 있다.

1. lionproject/templates 폴더를 생성하고 base.html을 생성한다

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initia-scale=1.0">

    </script>
    <style>
        body {
            text-align: center;
        }
    </style>
</head>

<body>
    <nav class="navbar navbar-expand-lg navbar-light bg-light">
        <div class="container-fluid">
            <a class="navbar-brand" href="#">Navbar</a>
            <button class="navbar-toggler" type="button" data-bs-toggle="collapse"
                data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false"
                aria-label="Toggle navigation">
                <span class="navbar-toggler-icon"></span>
            </button>
            <div class="collapse navbar-collapse" id="navbarSupportedContent">
                <ul class="navbar-nav me-auto mb-2 mb-lg-0">
                    <li class="nav-item">
                        <a class="nav-link active" aria-current="page" href="#">Home</a>
                    </li>
                    <li class="nav-item">
                        <a class="nav-link" href="#">Link</a>
                    </li>
                    <li class="nav-item dropdown">
                        <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button"
                            data-bs-toggle="dropdown" aria-expanded="false">
                            Dropdown
                        </a>
                        <ul class="dropdown-menu" aria-labelledby="navbarDropdown">
                            <li><a class="dropdown-item" href="#">Action</a></li>
                            <li><a class="dropdown-item" href="#">Another action</a></li>
                            <li>
                                <hr class="dropdown-divider">
                            </li>
                            <li><a class="dropdown-item" href="#">Something else here</a></li>
                        </ul>
                    </li>
                    <li class="nav-item">
                        <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
                    </li>
                </ul>
                <form class="d-flex">
                    <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
                    <button class="btn btn-outline-success" type="submit">Search</button>
                </form>
            </div>
        </div>
    </nav>
 
 
 <!-- 중요한 부분 -->
    <div class="container">
        {% block content %}
        {% endblock %}
    </div>
</body>

</html>

2. home.html 코드 수정 

{% extends 'base.html' %}

{% block content %}

<h1>Blog Project</h1>
<div>
    <a href="{%url 'new' %}">Write</a>
</div>
<div class="container">
    {%for blog in blogs %}
    <div>
        <h3>{{blog.title}} </h3>
        {{blog.id}}
        {{blog.writer}}
        {{blog.summary}} <a href="{% url 'detail' blog.id %}"> ...more </a>
        <!--detail이라는 url에 요청을 보내는데, blog.id도 같이 보낸다.-->
        <br>
    </div>
    {% endfor %}
</div>

{% endblock %}

3. setting.py의 templates 부분의 DIR 수정

4. runserver ..(다른 html에도 똑같이 3줄을 추가해 적용한다)

home.html

urls.py 관리하는법

1. blogapp에 urls.py를 생성한다.

2. blog/urls.py코드 작성하기

from django.contrib import admin
from django.urls import path
#from blog.views import *  
from .views import * 

urlpatterns = [
    #path('admin/', admin.site.urls),
    #path('', home, name="name"),
    path('<str:id>', detail, name="detail"), 
    path('new/', new, name="new"),
    path('create/', create, name="create"),
    path('edit/<str:id>',edit,name="edit"),
    path('update/<str:id>', update, name="update"),
    path('delete/<str:id>', delete, name="delete"),
]

3. lionproject/urls.py 코드 수정하기

from django.contrib import admin
from django.urls import path, include
#from blog.views import *  
from blog.views import home

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', home, name="name"),
    path('blog/', include('blog.urls'))
]
