1、Window open() 方法
http://www.runoob.com/jsref/met-win-open.html
效果图
2、admin的pop添加按钮
3、stark之pop功能
1、父相子绝
2、多对多字段如何渲染
3、isinstance判断类型
4、 一对多或多对多字段的关联模型
5、bootstrap页面自适应col-xs-8
6、model表显示的是__str__
7、构造url
8、传递数据,window.open使用
3、知识点总结
1、pop功能：
1.在一对多和多对多字段后渲染 +
2.+对应的跳转路径
3.保存添加记录同时，将原页面的对应的下拉菜单中添加该记录
2、在一对多和多对多字段后渲染+
后台需要先判断 是否是 一对多 多对多字段
modelform, 遍历
for bfield in form:
print(bfield.field) # 是每个form字段对象
所以：判断是否是一对多，多对多字段
if isinstance(bfield.field, ModelChoiceField):
bfield.is_pop = True # 为特殊字段加上特有属性，方便前端判断。 注意：ModelMultipleChoiceField（多对多） 继承 ModelChoiceField（一对多）
ModelChoiceField 继承 ChoiceField
3、+对应的跳转路径
form表单得一对多，多对多得字段对象
bfield.field.queryset.model # 相关联得模型！！<class 'app01.models.Publish'>
#（模型表得对象去找 filter_field_obj.rel.to.objects.all()，到to是模型。） 根据queryset找model queryset.model
根据model找queryset model.objects.all() related_model_name = bfield.field.queryset.model._meta.model_name # publish
related_app_label = bfield.field.queryset.model._meta.app_label # app01 反向解析url
_url = reverse("%s_%s_add" % (related_app_label, related_model_name)) # 为bfield添加自己特有的url,
# ?后面是为了，区分是top,还是正常页面打开/add/，方便之后关闭,以及赋值。
bfield.url = _url + "?pop_res_id=id_%s" % bfield.name
4、关闭弹出得top页面
top弹出，关闭页面，回到到原页面；
正常添加，跳转到list页面； 返回 res = {"pk":obj.pk, 'text':str(obj), "pop_res_id": pop_res_id}
到pop.html,方便关闭pop页面 pop.html:
关闭以及将接收得数据传到原页面上！
window.opener.pop_response("{{ res.pk}}","{{ res.text }}","{{ res.pop_res_id }}");
window.close()
5、原页面接收数据，并显示刚添加得数据（window.opener）
拿到 id, text, pop_res_id
动态创建 option append到对应得下拉框中，并选中；
var $option = $("<option>");
$option.html(text);
$option.val(pk);
$option.attr('selected','selected'); $('#'+pop_res_id).append($option)
6、前端展示：定位，（父相子绝）
<div style="position: relative">
{% if field.is_pop %}
<a onclick="pop('{{ field.url }}')"><span style="font-size: 23px;position: absolute; right: -23px; top: 25px;">+</span></a>
{% endif %}
</div>
7、补充：
ChoiceFiled
ModelChoiceFiled（ChoiceFiled） ---- select(单选) --- ForeignKey
MultiModelChoiceFiled （ModelChoiceFiled）----select(多选) --- ManyToManyField Book模型，form表单，modelform;
modelform帮我们转成了form表单；
bootstrap页面自适应： col-xs-8
