1、打开命令行窗口新建Django工程，并在工程下创建一个应用，命令如下：django-admin startproject djsearchcd djsearchpython manage.py startapp book
2、使用开发工具打开上一步创建的工程，修改工程的settings.py注册应用，并添加模板文件目录，彭榧逡钚修改部分的代码如下：INSTA讣嘬铮篌LLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'book.apps.BookConfig']TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR,'templates')], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, },]
3、在应用的models.py创建模型类，代码如下:from django.db import models# Create your models here.class BookModel(models.Model): name = models.CharField(max_length=50) content = models.TextField(max_length=800)在应用的admin.py注册模型类，代码如下：from django.contrib import adminfrom .models import BookModel# Register your models here.admin.site.register(BookModel)
4、在terminal使用命令生成数据库迁移文件，迁移数据库，创建超级用户python manage.py makemigrationspython manage.py migratepython manage.py createsuperuser
5、登录admin页面，添加若干书籍
6、在工程的urls.py文件，include应用的urls.pyfrom django.contrib import adminfrom django.urls import path,includeurlpatterns = [ path('admin/', admin.site.urls), path('book/',include('book.urls'))]在应用的urls.py文件，添加到视图的路径from django.urls import pathfrom . import viewsurlpatterns = [ path(r'search/',views.search)]
7、在应用的views.py文件，添加search函数from django.shortcuts import renderfrom .models import BookModelfrom django.db.models import Q# Create your views here.def search(request): sc = request.GET.get('search',None) context = None if sc: print(sc) booklist = BookModel.objects.filter(Q(name__icontains=sc)) context = {'booklist':booklist} return render(request,'booksearch.html',context)
8、在工程根目录创建templates文件夹，并在文件夹创建bootlist.html文件，代码如下;<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>book</title></head><body> <form action="/book/search/" > <input type="text" name="search" placeholder="搜索书籍..." required > <input type="submit" value="提交"> </form> {% if booklist %} {% for book in booklist %} <li>{{ book.name }}</li> {% endfor %} {% endif %}</body></html>
9、运行服务器，打开搜索页面，输入python,提交后，页面如下图，搜索成功
