展示客户列表页面--------搜索

第一步：views

@login_required
def display_table_objs(request,app_name,table_name):

    print("-->",app_name,table_name)  # 这是通过url取到的，
    #models_module = importlib.import_module('%s.models'%(app_name))
    #model_obj = getattr(models_module,table_name)
    admin_class = king_admin.enabled_admins[app_name][table_name]
    #admin_class = king_admin.enabled_admins[crm][userprofile]

    if request.method == "POST": #action 来了

        print(request.POST)
        selected_ids = request.POST.get("selected_ids")
        action = request.POST.get("action")
        if selected_ids:
            selected_objs = admin_class.model.objects.filter(id__in=selected_ids.split(','))
        else:
            raise KeyError("No object selected.")
        if hasattr(admin_class,action):
            action_func = getattr(admin_class,action)
            request._admin_action = action
            return action_func(admin_class,request,selected_objs)

    #object_list = admin_class.model.objects.all()
    object_list,filter_condtions = table_filter(request,admin_class) #过滤后的结果

    object_list = table_search(request,admin_class,object_list)  # 查询后的结果

    object_list,orderby_key = table_sort(request, admin_class, object_list) #排序后的结果
    print("orderby key ", orderby_key)
    paginator = Paginator(object_list, admin_class.list_per_page)  # 分页

    page = request.GET.get('page')
    try:
        query_sets = paginator.page(page)
    except PageNotAnInteger:
        # If page is not an integer, deliver first page.
        query_sets = paginator.page(1)
    except EmptyPage:
        # If page is out of range (e.g. 9999), deliver last page of results.
        query_sets = paginator.page(paginator.num_pages)

    return render(request,"king_admin/table_objs.html",{"admin_class":admin_class,
                                                        "query_sets":query_sets,
                                                        "filter_condtions":filter_condtions,
                                                        "orderby_key":orderby_key,
                                                        "previous_orderby": request.GET.get("o",''),
                                                        "search_text":request.GET.get('_q','')})

第二步：tag

不需要tag
直接把要搜索的内容传递到后端，然后后端根据这个去数据库查询就可以了

第三步：html

                      <div class="col-lg-3"　>
                        <input type="search" style="margin-left:15px" name="_q" class="form-control"  value="{{ search_text }}" placeholder="search by {% for search_field in admin_class.search_fields %}{{ search_field }},{% endfor %} ">
                      </div>
                      <div class="col-lg-2"　>
                        <button type="SUBMIT" class="btn btn-success">search</button>
                      </div>
