注意,我将templates定义在项目的同级目录下:
在settings.py中配置
TEMPLATES = [ { 'BACKEND': django.template.backends.django.DjangoTemplates','DIRS': [os.path.join(BASE_DIR,'templates')],APP_DIRS: True,OPTIONS: { context_processors: [ django.template.context_processors.debugdjango.template.context_processors.requestdjango.contrib.auth.context_processors.authdjango.contrib.messages.context_processors.messages![]()
urls.py
from django.urls import path from . views app_name=person urlpatterns=[ path(test/test/<int:pn>',views.test,name=test),]views.py
from django.shortcuts render from .models Book from django.core.paginator Paginator def test(request,pn=1): #获取所有的查询 book_obj=Book.objects.all() 传给paginator,每页显示两条 paginator=Paginator(book_obj,2) pn是显示第几页,默认是第一页 page=paginator.page(pn) 将page通过context传给前端 context={page:page} return render(request,test/test.htmlclass Book(models.Model): id = models.AutoField(primary_key=True) title = models.CharField(max_length=128,null=False) def __str__(self): return "book_title:{}".format(self.title)
tempates/test/test.html

<!doctype html> <html lang="> <thread> <tr> <th>id</th> <th>title</th> </tr> </thread> <tbody> <tr> <td width=">3</td> <td width=">java</td> </tr> <tr> <td width=">6</td> <td width=">zabbix从入门到精通</td> </tr> </tbody> </table> </div> <!--底部分页按钮显示--> <div style=" > <li><a href=/test/1" aria-label=">«</span></a></li> <li><a href=">1</a></li> <li><a href=/test/2">2</a></li> <li><a href=/test/3">3</a></li> <li><a href=" aria-label=">»</span></a></li> </ul> </div> </nav> </div> </body> </html>总结:这是实现分页最简单的了,至于美观,可以结合bootstrap来进行美化。
技术总结:最基本的是Paginator里面的一些值(当然此处我并没有去尝试其他的,有兴趣的可以去搜下,也挺简单的)。然后其中的一个就是前端pn值如何通过url传值给后端,注意标蓝的地方。
学习不易,且学且珍惜!!!
