list页面-按照choice筛选丶传condition过滤筛选项丶筛选与显示同步

1.list页面:筛选功能优化,显示choices,传condition过滤筛选项

list_filter = [

    # sites.FilterOption("name",False,lambda x:x.name,lambda x:x.name),#这种配置无意义

    sites.FilterOption("consultant",False,condition=Q(depart=1)),#传条件以显示筛选项

    sites.FilterOption("gender",False),#choices

]

显示choices主要逻辑:如果_field.choices有值,就把_field.choices当做data_list送上去显示,而condition筛选则是不似以前无脑all()将表中对象全部显示.

def gen_list_filter(self):

 

    for option in self.model_config.list_filter:

 

        if option.is_func:

            data_list = option.field_or_func(self.model_config,self,option)

        else:

            _field = self.model_config.model_class._meta.get_field(option.field_or_func)

 

            if isinstance(_field, ForeignKey):

                data_list = FilterRow(option, self, _field.rel.model.objects.filter(option.get_condition), self.model_config.request.GET)

            elif isinstance(_field, ManyToManyField):

                data_list = FilterRow(option, self, _field.rel.model.objects.filter(option.get_condition), self.model_config.request.GET)

            elif hasattr(_field,"choices") and _field.choices:

                # print(_field.choices) #((1, '男'), (2, '女'))

                data_list = FilterRow(option, self, _field.choices, self.model_config.request.GET,is_choices=True)

            else:

                data_list = FilterRow(option, self, _field.model.objects.filter(option.get_condition), self.model_config.request.GET)

 

        yield data_list

 

option.get_condition:

@property

def get_condition(self):

    if self.condition:

        return self.condition

    else:

        return Q()

2.list页面筛选与显示同步--后端获取搜索条件执行搜索返回--model_class._meta._get_fields()包含类中最全的字段.

filter_condition:获取搜索条件

@property

def filter_condition(self):

    # filed1 = [i.name for i in self.model_class._meta.fields]

    # print(filed1)

    # print('------------------')

    #

    # filed2 = [i.name for i in self.model_class._meta.many_to_many]

    # print(filed2)

    # print('------------------')

 

    filed3 = [i.name for i in self.model_class._meta._get_fields()]#包含的字段最全

    # print(filed3)

    # print('------------------')

 

    con = {}

    for k in self.request.GET:

        if k not in filed3:

            continue

        v = self.request.GET.getlist(k)

        k = "%s__in"%k

        con[k]=v

 

    return con
