[Python+Django]初心者笔记8(从数据明细页做foreign key外部超链接)

想要在Book的明细页，加入foreign key的作者的外部超链接的话，依照以下步骤即可：
在catalog/urls.py的urlpatterns加入这段：增加author-detail的 url mapping机制

#加入Author数据表的详细数据网页的url mapping
path('author/', views.AuthorDetailView.as_view(), name='author-detail'),

在catalog/views.py的最下面加入这段：增加author-detail的server side取db数据的行为

class AuthorDetailView(generic.DetailView):
    """
    Generic class-based detail view for an author.
    """
    model = Author    

新增这个文件/locallibrary/catalog/templates/catalog/author_detail.html,.html档内容如下:

{% extends "base_generic.html" %}

{% block content %}
  
Author: {{ author.first_name }}
    
  
first_name: {{author.first_name}}
  
last_name: {{author.last_name}}
  
date_of_birth: {{author.date_of_birth}}
  
date_of_death: {{author.date_of_death}}

  

    
Author's Books
    
    {% for book in author.book_set.all %}
    
    
    
title: {{book.title}}
    
summary:{{book.summary}}
    
    {% endfor %}
  
{% endblock %}

book_detail.html里面的一个author的超链接，原本是空的超链接，改成下面这样：

Author: {{ book.author }}
 

这样就可以正确显示了author_detail：

这篇大概是这样…
