首页展示文章搭建
首页展示文章搭建
一、后端
头像渲染配置，图片防盗链
1.文章展示
# 个人站点展示
@login_required
def index(request):
article_list = models.Article.objects.all()
# 分页器
page_obj = Pagination(current_page=request.GET.get('page', 1), all_count=article_list.count())
article_list = article_list[page_obj.start: page_obj.end]
return render(request, '03index.html', locals())
# 账号注销
def logout(request):
"""
注销
:param request:
:return:
"""
auth.logout(request)
return redirect('/login/')
# 重置密码
def set_password(request):
print(request.POST)
back_dic = {"code": 1000, 'msg': ''}
if request.POST:
old_password = request.POST.get('old_password')
new_password = request.POST.get('new_password')
confirm_password = request.POST.get('confirm_password')
# 判断两次密码是否一样
if new_password == confirm_password:
if request.user.check_password(old_password):
request.user.set_password(new_password)
request.user.save()
else:
back_dic['code'] = 2000
back_dic['msg'] = '旧密码输入错误！'
else:
back_dic['code'] = 3000
back_dic['msg'] = '两次密码输入不一样！'
return JsonResponse(back_dic)
return redirect('/index/')
2.文章分页
class Pagination(object):
def __init__(self, current_page, all_count, per_page_num=4, pager_count=5):
"""
封装分页相关数据
:param current_page: 当前页
:param all_count: 数据库中的数据总条数
:param per_page_num: 每页显示的数据条数
:param pager_count: 最多显示的页码个数
用法:
queryset = model.objects.all()
page_obj = Pagination(current_page,all_count)
page_data = queryset[page_obj.start:page_obj.end]
获取数据用page_data而不再使用原始的queryset
获取前端分页样式用page_obj.page_html
"""
try:
current_page = int(current_page)
except Exception as e:
current_page = 1
if current_page < 1:
current_page = 1
self.current_page = current_page

page_html_list = []
