组件添加模糊搜索功能

Posted 2020-10-12 jec1999

1.前端发送搜索请求,

 

<!-- 定制模糊搜索 开始 -->

{% if cl.search_list %}

    <div class="row">

        <form action="">

            <input type="text" name="{{ cl.search_attr.name }}" value="{{ cl.search_attr.value }}" class="form-control"

                  style="display: inline-block;width: 250px" placeholder="请输入关键字">

            <button type="submit" class="btn btn-primary">

                <span class="glyphicon glyphicon-search"></span>

            </button>

        </form>

    </div>

{% endif %}

<!-- 定制模糊搜索 结束 -->

 

 

2.后端取出来作为组拼搜索条件

@property

def search_condition(self):

    """获取模糊搜索条件"""

    con = Q()

    con.connector = "OR"

    val = self.request.GET.get(self.q)

    if not val:

        return con

    for k in self.get_search_list():

        k="%s__contains"%k

        con.children.append((k,val))

    return con

 

data_list = self.model_class.objects.filter(**self.filter_condition).filter(self.search_condition).distinct()

 

3.支持可配置式,子类里面复写并传值才显示搜索框

search_list=[]

def get_search_list(self):

  """获取搜索的列,即将会在数据库的哪些列中搜索这些信息"""

  search_list = []

  search_list.extend(self.search_list)

  return search_list
