【CRM客户关系管理】20.增加详情页分页功能

## 分页 修改分页（设置默认显示多少条数据） ### 修改父类默认分页个数 在djadmin应用的djadmin_base.py中增加一个`list_per_page`属性，当没有在子类中定义该值时，直接使用父类的属性 ```python # djadmin/djadmin_base.py class BaseDjAdmin(object): list_display = [] list_filter = [] search_fields = [] readonly_fields = [] filter_horizontal = [] list_per_page = 5 ``` ### 修改详情页获取分页值 修改djadmin应用的views.py ```python @login_required def table_detail(request, app_name, model_name): """取出指定model里的数据返回到前端""" # 拿到admin_class后，通过它获取model admin_class = site.enable_admins[app_name][model_name] # print(admin_class) # 执行djadmin.py定义的注册模型类 queryset = admin_class.model.objects.all().order_by('-id') # print(queryset) # 进行过滤 queryset, filter_conditions = get_filter_result(request, queryset) # 将过滤字典保存到全局注册类中 admin_class.filter_conditions = filter_conditions # 搜索 queryset, keyword = get_search_result(request, queryset, admin_class) admin_class.search_keyword = keyword # 将搜索字符串保存到全局类中 # 排序，返回排序的结果和排序的字段字典 queryset, current_order_field = get_order_result(request, queryset, admin_class) # print(current_order_field) # {'consult_content': '4'} # 如果有排序，保存排序的值，用于模板中在分页模块显示 if current_order_field.values(): current_order_value = list(current_order_field.values())[0] else: current_order_value = '' # 查询集结果分页 # paginator = Paginator(queryset, 10) # Show 10 contacts per page paginator = Paginator(queryset, admin_class.list_per_page) # 获取djadmin.py中自定义的分页数量 page = request.GET.get('page') try: queryset = paginator.get_page(page) except PageNotAnInteger: queryset = paginator.get_page(1) except EmptyPage: queryset = paginator.get_page(paginator.num_pages) return render(request, 'djadmin/table_detail.html', locals()) ```
