django数据库的使用

在某一个app文件下创建一个model.py的文件添加如下内容

from django.db import models

# Create your models here.
class BlogArticle(models.Model):
    title = models.CharField(max_length= 50)
    author = models.CharField(max_length= 20)
    time = models.IntegerField(default = 0)

进入到项目文件夹下面使用命令
python manage.py makemigrations

python manage.py migrate

分页与数据结构无关

下面是一个简单的分页测试

html页面

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
{% for article in page_obj %}
        <div>## {{ article }} ##</div>
{% endfor %}

{% for page_num in paginator_obj.page_range %}
        <a href="?page={{ page_num }}">{{ page_num }}</a>
{% endfor %}

</body>
</html>

views.py

def page_demo(request):
  lista=[]
    for i in range(1, 96):
  title = "title" + str(i)
        content = "text" + str(i)
        lista.append(content)
    paginator_obj = Paginator(lista, 5)
    request_page_num = request.GET.get('page', 1)
    page_obj = paginator_obj.page(request_page_num)
    total_page_number = paginator_obj.num_pages
    return render(request, 'page_demo.html', {'page_obj': page_obj, 'paginator_obj': paginator_obj})
