The basic knowledge points are all finished. Next, complete the sample project Li
The code needed now includes three aspects, which are in no order.
- 1. Define view
- 2. Define URLconf
- 3. Define template
Definition view
Write the file booktest/views.py as follows:
from django.shortcuts import render
from booktest.models import BookInfo
#Home page, showing all books
def index(reqeust):
#Search all books
booklist = BookInfo.objects.all()
#Pass the book list to the template and render the template
return render(reqeust, 'booktest/index.html', {'booklist': booklist})
#Detailed page, receive the number of the book, query according to the number, find all the heroes of the book through the relationship and display
def detail(reqeust, bid):
#Corresponding books according to book number
book = BookInfo.objects.get(id=int(bid))
#Find all hero information in the book
heros = book.heroinfo_set.all()
#Pass the book information to the template, and then render the template
return render(reqeust, 'booktest/detail.html', {'book':book,'heros':heros})
Defining URLconf
Write the file booktest/urls.py as follows:
from django.conf.urls import url
#Import view module
from booktest import views
urlpatterns = [
#Configure homepage url
url(r'^$', views.index),
#Configure the detailed page url, d + represents multiple numbers, parentheses are used for values, it is recommended to review the regular expressions
url(r'^(\d+)/$',views.detail),
]
Defining templates
Write templates/booktest/index.html file as follows:
<html>
<head>
<title>home page</title>
</head>
<body>
<h1>List of books</h1>
<ul>
{#Traverse book list#}
{%for book in booklist%}
<li>
{#Output the book name and set the hyperlink. The link address is a number#}
<a href="/{{book.id}}/">{{book.btitle}}</a>
</li>
{%endfor%}
</ul>
</body>
</html>
Write templates/booktest/detail.html file as follows:
<html>
<head>
<title>Detailed page</title>
</head>
<body>
{#Output book title#}
<h1>{{book.btitle}}</h1>
<ul>
{#Find all the heroes of the book through relationships and traverse#}
{%for hero in heros%}
{#Output hero's name and description#}
<li>{{hero.hname}}---{{hero.hcomment}}</li>
{%endfor%}
</ul>
</body>
</html>
