1、编辑按钮构建完成
1、必备知识预习
第一个会打印5.
第二个输出alex
alex是person类的实例对象，getattr()的用法就是alex拥有s方法的话，那么就执行。这里s是字符串用一个反射把字符串变成方法。
第三个是输出123，并且eat... 这里类可以直接调用自己的方法。不一定非得是实例对象。
第四个
第一个调用本身的__str__方法返回名字。
alex
第二个却是将alex这个对象变成字符串。
<__main__.Person object at 0x0000016951BDD5F8>
2、mark_safe模块：将html标签安全传输
from django.utils.safestring import mark_safe #这样的话，django就不会去给你转义了。 return mark_safe("<a href="">编辑</a>")
3、构造表单数据
4、反向解析

2、构造表头，删除，checkbox，links编辑
1、必备小知识
2、list_display显示表头
3、verbose_name显示中文
4、list_display_links编辑link构造
3、代码+总结
1、总结
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，全选/全不选
$(‘#choice‘).click(function () {
if($(this).prop(‘checked‘)){
$(‘.choice_item‘).prop(‘checked‘,true)
}else{
$(‘.choice_item‘).prop(‘checked‘,false)
}
})
2、starkadmin.py
from stark.service import stark from .models import * class AuthorConfig(stark.ModelStark): list_display = [‘nid‘, ‘name‘, ‘age‘] list_display_links = [‘name‘,‘age‘] stark.site.register(Book) stark.site.register(Publish) stark.site.register(Author,AuthorConfig) stark.site.register(AuthorDetail) print(stark.site._registry)
