stark - 数据列表
一、效果图
二、数据列表
知识点:
完成
(list_display)
(list_display_links)
1.根据str,拿字段对象,取中文
val = self.model._meta.get_field(field).verbose_name
2.模型名称,app名称
model_name = self.model._meta.model_name
app_lable = self.model._meta.app_label
3.判断是否可调用
if callable(field):
val = field(self, header = True)
4.字符串找对象得属性,反射
val = getattr(data, field)
5.返回标签
return mark_safe("<input id='choice' type='checkbox'>")
6.插入数组[]
temp.append(ModelStark.checkbox)
temp.extend(self.list_display)
7.反向解析,含正则
_url = reverse("%s_%s_delete" % (app_label, model_name), args=(obj.pk,))
_url = reverse("%s_%s_add" % (app_label, model_name))
8.复选框
$('#choice').click(function () {
if($(this).prop('checked')){
$('.choice_item').prop('checked',true)
}else{
$('.choice_item').prop('checked',false)
}
})
